Toshiba Satellite M35X. How to fix most common laptop problems.
Toshiba Satellite M35X is a very popular model in the United States. In general, most Toshiba Satellite M35X laptops suffer from the same problems. Here’s a disassembly guide.
Improperly grounded top cover assembly. If the top cover assembly wasn’t grounded properly, then laptop may lock up or freeze up when you touch it in the speaker area. It happens because of a static electricity discharge. This problem was fixed on some laptops, but still there are a lot of laptops with unmodified top cover assembly. This problem should be covered under warranty even if you laptop is not under warranty anymore.
Poorly designed DC-IN power jack on the system board. Overtime, the DC power jack gets disconnected from the system board. If it happens, you will experience a problem with charging the battery or the laptop may not start at all.

Laptop CPU overheating. It is a very common problem for some Toshiba laptops. If a laptop CPU overheats, then the laptop shuts down without by itself without any reason. Read more:

You can use the disassembly guide to take apart Toshiba Satellite M35X notebook and repair it yourself. Do not open the case if your laptop is still under warranty.

HAVE a Toshiba M35X-S329 had a power jack problem replaced
that. Put everything back , It run it great no more losing power and all ,but now if I touch the laptop around where the power plug is the screen goes off and everything else stays on.
I reboot it and sometimes everything will come on as far as the power but then stops ,blank screen. So maybe there is another problem . I will tap it around where the video plug is and then reboot and it will be okay ,then I touch that area it will go off.I guess the mother board..Right?

how do i restore my toshiba satellite m35x- back to factory settings

I have the solution for the non booting Toshiba m35 that I wrote almost a year ago. This tutorial is applicable to laptops that shut down without any warning, laptops that turn on only sometimes, and laptops that simply refuse to turn on (LEDs blink, fan spins up for a second and then everything just goes dead). So if your laptop does not turn on, it goes completely dead within a few minutes after bootup, here’s the link to the tutorial. The repair takes about an hour, there’s no need of replacing any parts, reinstalling any software or any other thing. The only investment in repairing your laptop with this tutorial is your time. Basically, you can repair your laptop within the hour, without spending any money for any parts or software.

I have a M35X-S3112. The screen fails to light up or goes black while in use. Pushing the close button multiple times usually brings the screen back to life. Each push of the close button will cause a flicker or flash or attempt to light up on the screen. Sometimes the close button will restore the screen for the duration of use, other times it’s only temporary.
Any ideas?

I have a toshiba m35x s111 and sometimes when I press the start button I hear a beeping sound and I see nothing on the screen. I then unplug the unit and try to restart again. Sometimes it comes on and sometimes it reverts back to the beeping sound. The laptop is about 5 years old so I don’t know if it’s on it last leg or not. Got any suggestions?

On step 15 there is a photo that I think shows the bios chip.
It looks to me to be socketed. Can you confirm this?

I’ve tried removing the memory to see if it was the culpert. Still having the same problem.
Here’s more info: When the booting up problem occurs, and after several restarts, the laptop will fully boot up, but then I discover that my D drive would go missing.
And this only happened once, where the computer just shut off by itself.
Any more suggestions?

I have a M35X that keeps locking up (freeze) requiring me to give it the finger. I have gone thru all the virus work, registry, ran memory check program. Any idea’s where to look next

a,
I think it’s just a coincidence. Most likely your problem is not related to the virus infection.
It’s possible that your problem is related to the memory failure.
You have two modules installed in your laptop, correct? It’s very unlikely that both memory modules failed at the same time.
You can try removing memory modules one by one and test the laptop with each one separately. It should start fine when the bad module is removed.

I have a toshiba satellite m70 laptop.
I got hit with a virus, I used mbam to remove everything, but a couple of days later when I try to start up my laptop it won’t go past the toshiba logo page. Even if I press F12 or F2 it just stalls there, so I had to power down and restart it. Sometimes I have to do that up to 15 times for it to fully boot up.
I used Chkdsk to see if there was any problems, nothing was found.
What can be causing this?

Hi there, I’m looking for help with Toshiba Satellite M40X please. Product was bought in Canada & is out of warranty. Laptop keeps freezing, I have put in the recovery disc, but it is still freezing after about an hour or less working on it. If anyone can help I would be very grateful.

Has anyone used the repair that Jerry (jrhirsch) has outlined for isolating the jack from the motherboard and/or used his repair service. I’d like to get some feed-back form anyone that has. Thanks in advance.

Marc F,
First of all, check RAM modules. If you have two RAM modules installed, remove them one by one and test the laptop with each one separately. Try installing a known good RAM module and test the laptop again.
If replacing/reconnecting/swapping memory doesn’t help, most likely you have a problem with the motherboard.

I have a TOSHIBA SATELLITE M35X-S149 that does not boot. The blue power light and fan comes on (fan ran for 5 seconds and stop), nothing else.

Need help PLEASE. I was cleaning my husbands M35X-S149 laptop. I was wiping down the side with a cloth, on the right side there is a small square headed button I pushed on it and something right next to the button came out. I pushed the card or what ever it is that came out back into the case I can not get the square headed button to stay in as it was before. it is sticking out of the case about 1/2 of an inch. Husband is at work, I would really like to get this taken care of before he returns. THANK You

Alex,
Have you tried replacing memory?
I’m pretty sure you can make it boot if you apply some pressure on the motherboard and turn on the laptop. Apply some pressure on the area close to the left hinge with your thumb and turn the laptop on while applying the pressure. Will it turn on this way?
I’ve seen this many times before. If that’s the case, there is a problem with the motherboard and it has to be replaced.

I have an M30X with the famous power jack problem. I tried to diassemble it and got 90% of the way before I realized I had broken not only the keyboard cable connector clip, but also the two flat cable connector clips (also on the system board) from the top assembly. I saw in earlier posts that Toshiba does not sell these cable clips, and my service center doesn’t have any. I stopped the disassembly without fixing the power jack to see if I could reassemble the flat cables. Most of the clips for the keyboard connector and the power light connector were still intact (only one pin broken) and I was able to wedge the cables back into the connectors. For the small touchpad connector, the clip was hopelessly broken, but I found that I could wedge a small piece of a credit card between the conector and the cable and it worked. I would like to disassemble the machine again so I can finally repair the power plug, but am afraid I won’t be able to get the flat cables to work again without the proper clips. Does anyone know anywhere where I can get these plastic clips? I’m sure I’m not the only one who has broken these.

i have a m35x-s111 and i have no video i opened it and checked everything but everything looks fine. sometimes the tchiba logo come up when i turn it on but then goes away. i dont want to reboot it can i get any ideas on how to fix the problem?

I have a TOSHIBA SATELLITE M35X-S349 that does not boot. The blue power light and fan comes on (fan ran for 5 seconds and stop), nothing else.
This guide and the replies helped me learn a lot especially reply number 78 by Mr. 78 Jerry Hirsch. I tried replacing the DC Jack with a new one thinking it might solve my problem but it did not.
So my motherboard might have solder joints that broken on the 48 pin chip that is next to the DC jack or it that chip might be broken entirely.
I am now looking for someone who can repair this motherboard for me for a very reasonable price. I can’t afford to buy a replacement motherboard or a new laptop.
Thanks and Regards.

I was following the Disassembling Toshiba Satellite M35X laptop guide which was a big help but under step 4 it says to carefully remove the dvd drive how does one go about doing that skillfully? do I just pull it out is there some latch or something do easily remove the dvd drive?

Josh,
Scan your laptop for viruses and spyware. You can use AVG antivirus and SpyBot spyware removal tools.

Hello, My Satellite M35x-S1142 speed has significantly decreased over the last 5 months. It now takes several minutes to pull up a website. My other computer on the same router is not slow at all. Any suggestions to speed things up? I have already upgraded the RAM – I added 1024MB to the 512MB.
Thanks!

Hello,
I have a Satellite M30X-113 with a Intel Pentium M Processor 725 1,6 Ghz, I want to know if my notebook is capable to support this CPU Intel Pentium M Processor 765 2.10 GHz , and if it’s worth in terms of performance? I also have the latest build of the BIOS v2.0 released on 11/02/09.
Thanks for your answer

I read the IrisVista “Disassembling Toshiba Satellite M35X laptop” guide.
Since my problem is the heatsink, do I need to follow all the steps in sequence, or can I skip some and go straight to ArcticSilver-ing the heatsink and replacing it back?

My M40X was shutting down. I found this site and did the easy step first. I blew out the dust. That worked for a while but eventually, the fan started to sound like an electric razor.
I”m mecahnically & electrically inclined and I hate to throw out and waste but I never thought to take a laptop apart. I poured over the pictures and it seemed like I might be able to do it. After calling a few service centers it loked like it was going to cost me $150. Then I found a replacement fan assembly on ebay for $22 and I figured what did I have to loose. $22??
To make a long story short, I followed your steps exactly and except for the anxiety of some of the cable connectors was able to replace the assembly and, incredibly, it booted up and is still running. I can hear the fan coming on/going off so I think the operation was a success. It took me just 1.5 hours to do it.
Even though mine was an M40X, I have to say how impressed with your instructions and tips. I’ll be highly recommending this site to everyone who wants to try to fix their laptop.
Thank you so much for your help.
