Toshiba m35 HP nc6000 Laptop Repair Manual

Apr 23, 2016 by     72 Comments    Posted under: Laptop Repairs

Did your laptop suddenly die and no matter what you do you can’t get it to power up again? Don’t worry, you’ve come to the right place.


You’re about to learn how to repair your non booting laptop in just one hour. No need of reinstalling anything. No need of buying new components. This 30-page PDF repair manual can help you do this fix even if you never did this before.


Toshiba m35 HP nc6000 Laptop Repair Manual 3rd Edition

So, let’s get started.

You probably have a laptop that’s a few years old, and now it just won’t power up no matter what you do to it: change the hard drive, replace the RAM, CPU, battery, new power brick and so on. Nothing seems to work. Your laptop just won’t boot up.



If your non-booting Toshiba or HP or Dell laptop has at least two of the listed symptoms, this repair manual could be useful to you:

  • when I press the Power button the laptop LEDs blink for a second and then it shuts down completely
  • at each attempt to boot, the CPU fan spins for a second and then everything shuts down
  • the DVD drive won’t open even though it does spin up for a second
  • the hard drive does spin up but the laptop does not boot
  • laptop turns on but the BIOS doesn’t show
  • Laptop does not power up at all

If your laptop behaves in this way, you’re set. This repair manual can get you under way and you can repair your laptop within the hour!

The Maxim 1978, Maxim 1532ETL or Maxim 8770 Chip Problem

When you try to power up your Toshiba Satellite or HP or Dell laptop, the computer goes through a Power-On Self Test sequence, aka POST and if this self diagnostics finds a problem with the hardware, it shoots out the appropriate error code. With desktops this comes as a series of beeps. With laptops it’s usually a series of blinks of all laptop lights.

So, when you notice that your laptop does not power up but the LEDs blink, for example Long-Short-Short-Long blink (aka 1001 error code), this means that you need the laptop repair manual and you can find what this error code means. Unfortunately, I’ve came across a ton of laptops that suffer from the same fate, but all of them shoot out a different error code.

What actually happens is that the motherboard (or main board, if you prefer) power regulating circuitry is failing, and in different laptops different components lose power. This is why each laptop shoots out a different error code, but what is in common is that all these error codes are actually pointing to a power-related issue.

From what I’ve seen sofar, any laptop that is produced between 2004 and 2009 use the Maxim 1987 or Maxim 1532ETL power regulator, or power driver. In post 2009 laptops, Maxim Inc. launched a new, beefed up power driver chip, the Maxim 8770, that also causes the same laptop failure. This is the infamous Maxim power driver chip failure, which makes the laptop motherboard useless. The failure is caused by an effect called chip creep (detailed explanation in the PDF repiar manual below).


Possible Maxim chip Repairs

Repair centers offer two solutions: opt for a new motherboard which costs about $300 plus the service fees, or get a new laptop. However, there is a way that you can save your old motherboard by fixing this Maxim chip problem.

In a nutshell, what you need to do is pull the motherboard out of the laptop and resolder the Maxim chip. The resolder is a touchy process, and if you’ve never done a similar repair to an SMD chip I strongly recommend this PDF illustrated manual.

Take advantage of my work here. I spent almost an entire year troubleshooting and research that finally resulted in this repair technique. I’ve searched the net for a very long time and failed to find a workable solution, so I decided to write one.


Supported models

It’s very difficult to narrow down a precise list of laptop makes and models that are affected by this Maxim power chip failure. The best way to know is to see the short list of symptoms and make sure your laptop has them. So make sure your laptop does have these symptoms listed previously. The most common issue is that the LEDs blink a few times, the CPU fan spins up for a second or two, and then everything shuts down. If the laptop has these symptoms, and is at least 2 years old chances are this Maxim chip problem is what’s bothering your laptop. In general, all laptops that experience the listed symptoms, and that are produced between 2002-2008, are likely to use this Maxim chip. Below is just a short list of most common laptops that users reported of having this Maxim chip issue:

  • Toshiba Satellite m30 series
  • Toshiba Satellite m35 series
  • Toshiba Satellite m 115 series
  • Toshiba Satellite A135 (uses a Maxim 8770 chip)
  • Toshiba Satellite a65
  • Toshiba Satellite A75
  • Toshiba Satellite L300 series
  • HP nc6000 series
  • HP nc7000 series
  • HP nc9000 series
  • Acer Aspire 4xxx series
  • Dell Latitude D600 series
  • Some Sony models
  • Some MAC models

  • hi thank you so much for your help it’ s really helpful but i have a question plz is that working also for Toshiba L505D-6947D? cause it make the same problem it’s just dead and when i ask one guy he say it’s a chip inside and he say it’s called power chip is that right?what’s the real name for it?thank you so much for ur help

    i would like to ask you plz is Toshiba satellite L505D-S6947 using also the Maxim power ic or chip?and if yes which kind of “max power chip”it using?i mean the serial number from that or how i know it’s exactly what i need ?

    • Hi Morris, Thanks for the question.
      The Toshiba L505 series use Maxim 1987 or in some instances Maxim 1532ETL. The chips have the same pinout, same function, and the only difference is year of manufacturing. Chances are your laptop will use the Max1987 power driver chip.
      Have in mind that the defect is not the chip itself. The chip is fine. All it needs is a quality resolder. There are several ways to tackle this resoldering project, which are explained and illustrated in detail in this repair manual. So, you won’t need to change the power driver chip. There are no component replacements. If you have a soldering iron, all you need for the repair is this repair manual, and that’s it. If you have resoldering experience and have disassembled laptops before, you can fix your L505 in under an hour.
      Hope this helps.

    • P.S. You can’t purchase the Maxim 1987 power driver chip. The production is discontinued. The only way to get it is if you’re registered (and approved) as research engineer with Maxim Semiconductors.
      Several months ago I asked Maxim to send me a few samples for testing, but that only confirmed that these chips hardly go bad. The defect is simply a soldering issue.

    • yes, the full model of the laptop is usually more than enough to get a matching motherboard. However, I must warn you that scrap motherboards are “cat in a bag” situations… you never really know what you’re getting. Before I pulled enough courage to do the repair on my Toshiba m35 motherboard, I bought a “working” motherbay off ebay only to realize that this “new, working” motherboard was also suffering from this Maxim chip problem. So, I was out of $150, and with two motherboards with the same defect. Of course, eventually I repaired them both, but I was still $150 short over a motherboard that I didn’t really need. I still have it somewhere, collecting dust.

  • hi Igor what do u think how much it will cost Max 1987 or Maxim 1532ETL ?
    thank you so much Igor

    • Morris, I dont think you can purchase the Maxim chip. They’re not in production any more. Last time I saw one for sale was over a year ago, and I think it was about $4, but I’m not sure. This was a long time ago.

      • in which website u see it Igor?

        • Here’s the link to the maxim chip store http://www.pchub.com/uph/laptop/507-29494-6753/Maxim-MAX1987-ETM-Power-IC.html, but as I said before, the chip on your laptop is perfectly fine. You dont need to change it. Hope this helps.

          • what do u think i have to do to make that dead laptop back to life again ?

          • You’ll just need to perform a quality resolder of the Maxim chip. As I said, there are several resolder methods, and they are all clearly described with plenty of images and illustrations in the repair manual. There are even a few embedded videos in the manual, so you’ll get a great resoldering manual that will help you fix your laptop in about an hour.

          • hi Igor,what do u mean by “perform a quality resolder of the Maxim chip” plz explain to me more i’m not genius like you hahaha .

          • Moris, the repair manual is a 30-page book that goes in detail to explain how to “perform a quality resolder of the Maxim chip” and explanations are well made so that almost anyone can do the repair. Please order the manual and I’m sure you’ll be more than pleased with your DIY repair project.

          • hi Igor,i have a question plz.if i need a new motherboard for my toshiba L505D-S6947,when i’m searching online about it i need only that serial number (toshiba L505D-S6947AMD) or there’s other serial number i must search about it to find the same motherboard .

            thank you so much my genius friend 🙂

  • I have no experience soldering. Can you recommend a basic, inexpensive soldering tool that is sufficient to apply the fix for Toshiba M35X problem? Anything you can point to on amazon.com?

    •  Any soldering iron with a fine tip will do. The point of the matter is that you need to know how to use the solder. As you can see in the tutorial, there are several resoldering techniques that you can pick from. If you’re the step-by-step person, then you can use the pin by pin approach and use a fine tip solder. If you’re the “do it quickly” guy then you can use the second approach where you don’t really need a fine tip at all.
      Here’s the first Amazon listing that seems OK, http://www.amazon.com/Wilmar-PENCIL-TYPE-SOLDERING-IRON/dp/B000N346SG/ref=sr_1_4?ie=UTF8&qid=1305824632&sr=8-4

  • Will this work for a Toshiba Equium L40-17M or an Advent 5421 Many thanks

    • if the symptoms match, then there’s a 99% chance it’s the identical problem.

  • Hi Igor, my laptop is a Tosh Satellite P30 from 2004 – it shows the symptoms as described:
    the laptop LEDs stay on, but at each attempt to boot, the CPU fan spins for a second and then everything shuts down – the DVD drive won’t open. Sounds like the same problem, but I can only find one Maxim chip on my board, at the opposite side to the power connector. It is a Max1902 and doesn’t look like the one in your Snapshot 3 – having 14 pins on two opposite sides only, but a google search does show it to be a power controller! So, do you think your repair manual will solve the problem on this one? Many thanks.

    • It’s worth a try, cant say for sure as I havent yet had a P30 in for repair, but if the symptoms match and the only power driver is a Max1902, then go ahead and do the resolder.
      If you want some help, you can take several closeups of the motherboard and email them to me.
      Post back the results, so others can benefit from your experience

  • You forgot the word Laptop in the first paragraph.

    • Thanks for the heads up. Fixed.

  • Is your manual downloadable, or is it hard copy only? (Wife works from home office; needs her pc like it was last night- working!)

    • Hi Dave,
      Yes, the manual is a digital product and you can download it the moment you make the payment. After payment you’ll be taken to the Downloads page where you can just click the Toshiba m35 HP nc6000 Laptop Repair Manual, and download the PDF file. It’s a a 25 megabyte file which has videos, so it’s intended to be viewed on a computer rather than being printed out.
      Hope this helps.

  • Forgot to add: Toshiba Satellite P305D S8834 with AMD Dual Core Turion Processor.
    Hope that helps.

    • I’m afraid I can’t tell for sure if your laptop has the Maxim chip… it’s impossible for me to tell for sure because there are motherboard revisions and what was used in one laptop model produced say in April, doesn’t have to mean that the same electronics will be used in a revised design manufactured in May. I’m sorry I can’t be of more help… I guess the best thing is to open up the laptop and look for the Maxim 1987/87xx chip. It’s a 10×10 milimeter chip, with pins on all four sides. Usually it’s around the power plug, but I’ve seen laptops where this chip is close to the CPU.
      Hope this helps.

  • i will try to fix my toshiba m35x thanks for helping us this site will help the million of users of laptop…….. thanks for sharing your knowledge god bless!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  • Hi There,
    I have a Toshiba laptop and my wireless reciever is not working. It picks up the signal from the router and it is shown on the screen in a list of wireless devices etc but after inputing the security code, it will not connect. I have been through the system information and found that on the drivers information that the eHome infrared reciever is disabled. I have gone into windows system32 drivers on the c: drive to see if I can enable it but it is in a file which I can only open with…….. but I don’t know what to open it with???

    Am I in the right area or am I way off the mark on this???? I have had a computer geek look into it but it was a very quick once over and said that I should maybe get a reciver booster I plug into the USB but I am sure it is something simple that just needs a bit of a tweak? It has worked on wireless before but I do have a couple of kids that may have unexpectanly turned something off.

    • Hi Jacquie,
      Judging from what you’ve told me, it may be that the disabled eHome module actually is an all-in-one, turning on and off the wireless/infrared/bluetooth devices. So you may want to look for a button on your laptop that has this functionality. Usually it’s above the keyboard somewhere. Or, it can be just a simple matter of wrongly imputing the security key. The best way to solve this is to type the password in notepad, to make sure you’re correctly inputting it, and then copy it into the required field.
      You’re way off track going to system32, there’s really nothing you can (or should) do there as a regular PC user. Sys32 is where the hardware drivers are located, but you cant turn on or off devices there. Instead, you can go to Start-Control Panel-System-Hardware Devices, and from the list, see if the WiFi is enabled or disabled.
      The best way to research a problem is to mention the laptop model and the symptoms, eg “toshiba m35 laptop wont turn on lights blink”, and then read up on the issue. I’m pretty sure there are other people out there that have faced the exact same problem, so it shouldnt be hard to find the solution. You’ll just need to set the search phrase properly.

      hope this helps

      • Ooo thanks for the quick reply – was expecting a couple of days!!!! No, I have the wireless switch on!!! and the device drivers are all up to date and have tried trouble shooting etc but they are all fine – nothing wrong! The security key is right as well – I have another two computers working off the same router……not at the same time though! It is probably the receiver itself that is not working???? Is there anything you can think of that may need enabling somewhere??? We have had the computer a few years – its a L300d?? It would seem that as far as the system is concerned, it all works. As I said, it does actually pick up the signal but will not connect……

        Kind regards

        • ok, l300…. not the best model by far…
          I guess the simplest way to check is to just buy a USB wifi, and see if that solves the problem. Or… before you buy it, see if you can reliably run big files off a USB memory stick. This will test the power stability on the USB ports and the data flow stability, so you dont end up purchasing a USB wifi and the USB ports arent working well. Remember that USB mouse or external keyboard isnt enough to establish if the USB ports are working well.

          • Ok. bit over my head when mentioning motherboards – reminds me of motherships and I don’t like SciFi!!!! Will try with a usb wifi – all the usbs work fine.

          • ok, keep us posted of what happens.

        • check your operating system if it’s 32 bit or 64bit, make sure you install the correct driver for your network card 


    •  yeah, sounds about right. that’s how my toshiba started acting up. I had that problem for a few months actually, before it completely died. In your case, you’ll need to do both repairs that are explained in the tutorial, but perhaps it will be best to first go with the Appendix section, and see how things go. It just may be enough, and you can get away with a fairly simple repair project.

  • Igor does the Toshiba Satellite P775 have the “Max Chip” problem?

    •  It’s hard to tell for sure until you actually open up the laptop and check.
      If the laptop has the listed symptoms, and is manufactured between 2003-2008, chances are it’s a Maxim chip, whether it’s 1532ETL, or 1987, or 87xx… they’re basically all doing the same function, which is to be a single point of total failure of mid-range laptops. Hope this helps.

  • Well I have to say, all of what I have read is very impressive. I love the Christian tweet.
    My question is, I have a Satellite A105-S2051 that When you press the power button,
    power on 5 seconds solid green-shuts down, does it 6 times then off. Power, hdd led and charging light led all on. I am praying for some good news here and this purchase is what I need.
    Thank you for being you.
    Have a blessed day.

    • Hey, thanks for the nice words, and for liking my tweet :). You may also like this new website I’m working on, http://www.theologybookreviews.com, and suggest a book you’d like reviewed.
      About the laptop, judging by what you describe, it does sound like this infamous Maxim chip problem.
      I think I had a client that had a 105, just not sure if it was the A or M series, and that laptop had a Maxim 1532ETL, as a replacement of the Maxim 1987. But they’re identical. So I’m guessing your laptop will have the 1532ETL, but it makes no difference for the repair. The process is exactly the same.
      The tutorial has three repair scenarios, each for a different level of skills, so you can choose which one suits you best.
      Let me use this opportunity to mention for everybody that there are ridiculous “repair” suggestions that claim putting the motherboard into an oven for 15 minutes will do the job. It won’t. It will just fill the oven with toxic gasses that will condensate on the oven walls, so next time mom makes an apple pie, you’ll have it with a twist of toxic elements. Bon-appetite.  
      Hope this helps.

  • I’ve got an M305D with similar symptoms.  With it plugged in, the fan will spin up for a second and then it dies.  With it unplugged and on just the battery, the fan runs continuously but it doesn’t post.  The only way to shut off the fan is to remove the battery.  I’ve pulled the motherboard but I don’t see any Maxim chip.

  • Am i expected to pay $37 for a book i’ll use once??? I don’t think so.

    • you’re getting a solution to a problem so you can solve it yourself, instead of paying three times as much for a repair, or twenty times as much for a new laptop. You’re not expected to do anything if you don’t like the deal.

  • can this work with a toshiba equium l20-264 which has the same problem???

    •  I’m not sure about the L20 model. If it’s the same symptom, it’s probably the same cause, but I cant say for sure cause I never had an L20 in for repair. The best way is to open the laptop and look for the Maxim chip. If it’s there, then this tutorial will help. If your laptop doesnt use a Maxim chip, then you’ll have to look elsewhere for a solution. Hope this helps.

  • I have a Toshiba Satellite A200 model number PSAF3A-0QJQ6D which is displaying the sort of problems described here, would this book help to solve the problems on the A200?

    •  yes, I think so. A while ago another A200 purchased the manual and reported back that he repaired the laptop. So I’d guess your laptop also uses the Maxim chip.

  • Thanks Igor going to purchase your book. Learning how to solder on the boards will be well worth it.

    • thanks for the purchase, dont forget to share your experience here, so other A200 owners can have first hand info, and other laptop repair enthusiasts could learn from your experience too. If it’s not too much trouble, you can also Like and Tweet this page, so your contacts can see the kind of repairs you’re working on.

  • will this manual cover the p305d-s8834 model
    thanks for reply

    • I think do. Not 100% sure, but I think your laptop uses the same power management hardware, using the Maxim 1987 or its successor Maxim 8770 chip. They’re basically the same shape and size, and their function is the same too. 

  • Does HP NC6120 have this problem with Maxim chip?


    • Hi Tomas. Yes, the NC6120 is part of the NC 6000 series, so the described problem is the same for your laptop too.

  • Ok I’ve taken laptop apart and don’t see any of the maxim numbers listed on my board is there more than those 3 u list above. I have no problem buying your book to help me but I want to male sure it will help first. When I power on my laptop the blue power light comes on and then nothing else. I bought a new hard drive already just incase. Any help or suggestions I can get before will be appreciated. Im always a little cautious when purchasing ebooks. My laptop is a Toshiba satellite M35-S359

    •  Hi Chris. The Maxim numbers can be 1532, 1987, 98xx. The size of the chip and its proximity to the power plug is what gives it away. Look for a 10×10 milimeter square chip close to the power supply. It should have 10-12 pins on each side, so a total of 40 or 48 pins depending on the Maxim number.
      You dont need a new hard drive as the problem is not with the hard drive. If your laptop blinks the lights a few times and then turns off the issue is with the power management of the motherboard. No amount of components replacement will fix the issue… unless you actually scrap the motherboard and get a new one.
      The only way to repair this defect is explained in the ebook.
      Hope this helps.

      • alright i ordered book i was charged twice and now cant even find it to download it. any suggestions.

        •  Hi Chris. Thanks for the purchase. I issued a full refund to the second payment and sent you a direct download link to the file. The link will expire in 24 hours, but you can always get the ebook again from the My Account page, where you’ll see a list of purchased products with accompanying download links to the far right side of the table.

  • Hi Igor,
    can you tell me if HP Compaq 6830s Notebook PC is on that list and known to have that bad chip. Or by this symptoms: it blinks 7x times orange(red) on power LED indicator and don’t startup without battery pluged. With battery and charging computer slows down and don’t boot up or boot up after hours…  With battery power and not charging it works like a charm.

    • The  HP 6800 series doesn’t use the Maxim chip, so this tutorial wont help you.
      The problem with the HP 6830 is twofold: a bad power supply that you will have to replace, and a bad capacitor that needs replacement.
      I’m working on the tutorial for the capacitor replacement, and hope on publishing it in the next couple of days.
      If you want, you can make a pre-order using the Buy Now option on this Toshiba tutorial, and I’ll email you the new PDF once I get it done. If you make the pre-order I’ll hurry up with the preps and get it done hopefully tomorrow.

      • Don’t hurry if for me.
        It’s not my computer, if they me want to repair then I’ll get back to you. If they want HP service then nothing I can do. But it will cost them more, I guess.

        • The standard operating procedure of HP certified repair technicians is to replace the motherboard and replace the power supply. The power supply is about $60, and the motherboard will be close to $350. Plus handling fee of at least $50, they’ll be looking at a price that doesnt make sense to invest in a laptop repair when there’s a brand new laptop for $600.
          The HP 6830 is a 17 inch laptop as far as I know, biz-class (but not reliable at all), and they can replace it with an Acer Aspire 7551, the one I use now, for only $600 with Win 7 Home Premium 64bit. I bought two of these, one for me and one for my wife. It’s quad-core AMD processor, 8GB ramand 500GB hard drive. Quite sufficient for web design and definitely more than enough for regular use: MS Office, surfing, etc.
          From this perspective, spending about $450 on a repair of probably a dual core laptop just doesnt make sense.
          Hope this info helps you and your client.

  • Does this guide work for a Toshiba Sattellite L675? I can’t find whether it has a maxim chip or not. I see that it has a IC chip. Is that different of the same?

    • The best thing to do is to send me several pics of the motherboard so I can take a look and let you know if this tutorial will help or not. I’ll contact you via email so that you have my email address for sending the pics.

  • in the l300 series which chip am i looking for?…i bought the pdf, as it says above that the l300 is included with these issues…

    • Thanks for the purchase. The L300 should use the Maxim 1532ETL chip and should be close to the power supply plug. But as there are several motherboard revisions (versions), be on the lookout for Maxim 8770 too. They are the same form and size as the Maxim 1987 chip in the tutorial so it shouldn’t be difficult to locate it. If you have problems locating the chip feel free to snap several hi-res pics of both sides of the motherboard and email them to me so I can help out.

  • thanks igor, what is your email addy?

  • Hey igor.. Just finished the soldering of the maxim chip.. And whalla it has turned on im just leaving it running now for few hours to see if it turns off.. Thats wat it was doing before.. Thanks for all your help

    • just buy the book guys, and follow the steps. I thought my laptop was a goner but its working as good as ever now, hard to believe that it was just this little maxim chip chip that causing the bother.. Thanks again Igor keep up the great work

  • hello guy somebody has other solutions I have done this with this technique but still not work I have an dell latitude d610 not turn on

    • Hi Abraham. I’m not familiar with the D610. If it’s using the Maxim chip mentioned in the tutorial then this fix should do the trick.

      • Hello igor yep, I speak about of the chip 1987,

        • When I was perfecting the process I had to try several times… and kill one motherboard on these practices. So you’ll have to do a very good job at resoldering/reflowing the chip. Another thing you may try is to take the board to an electronics repair shop and just tell them what you need done. Just a couple of weeks ago I had a need of replacing an SMD chip while retrieving data from a dead hard drive. I took the board to a repair shop, told the guy what I need done, and he did the work in about 5 minutes. He said it’s fine and there’s no need for paying him for the service but I gave him a cup of coffee worth of change, so we were both happy with the deal. If I had a board on my hands now, I’d do the same and not bother resoldering it myself. It’s way faster and way better to do a proper reflow. Hope this helps.
