First, Check to make sure that the memory is seated and hasn't worked loose.
Check to see if the fan comes on and runs. If yes, connect and external monitor and see if you ahve video on the monitor. If yes, you may have toggled the video off. If no, check to see that the Hard drive is seated properly. If that's not it, check to see if the CPU is seated properly. It may be that you, like a lot of other people have let the laptop overheat and have damaged the mother board. Good luck.

Best guess, overheated and damaged CPU or motherboard. If the CPU is damaged, you'll still get the indications you state. Good luck. Let us know how it goes.

Hi Hafiz,
I was reading your post and while I'm not fully familiar with your laptop. I know a thing or two about Toshiba laptops. Your model has a general problem with the soldering of the power connector. I read somewhere that if you resolder the three points on the power connector, you will bring it back to life. I have not done it myself because I never had this laptop.

On a general note, Toshiba laptops have similar problems as those of the Sony. The soldering of few parts come loose and the laptop gives light but no power. In your case, I would take this laptop appart and if you find two boards sitting on each other through a connection, I would check this part first. The problem usually lies in the lower board. It is also possible that all the soldering is fine but it is not sitting right. Make sure that all the connections are perfectly connected. I disagree with the previous post that you may have damaged the CPU. Simply because they are usually the last to go on any laptop. The design is made to give full protection to the CPU. You can also check if your CPU is dead or not by putting your finger on the heatsink and check the temperature. If after few minuts it warms up, your CPU is working fine.
If you take it appart you need to be very patient and make sure you disconnect the power and remove the battery. You will need good light, an eye magnification like the ones Jewelers use and a long sewing needle to check the connection.
Good luck.
Mike

I just tried to upgrade the cpu in my m35x-s149 from the celeron m 1.5 to a centrino 1.7. I got the same thing. The screen would not come on. When it re-installed the 1.5 it worked fine. Either the cpu I tried to use was bad or the s149 will not run with a 1.7. You might need to pick up a 1.5 which are fairly cheap on ebay.

Hi David,
I think the Centrino is a different technology than the Celeron. I tried replacing the Celeron on PCs but never tried on laptops, I think if you replace the Celeron with Pentiun 4 it should work. The question is if the Bios will accept the P4 CPU. Always update your Bios before any upgrades.

I too have experienced a similar problem with my mx35 s149. Initially it started freezing up and wouldn't even bring up the task manager on pushing ctrl alt del. then , it would have the power light come on but nothing happening. Left alone, it suddenly starts booting after anything from a few minutes to as much as 30- 40mins.

If I'm alert when it starts and hit F8 to go into safe mode, then all is ok. it's stable in safe mode, but if I miss it, then it continues to boot into XP and seems ok until suddenly it either just restarts, or briefly flashes the "blue screen of death" then attempts a restart. When it did boot to XP the one time, I spotted a popup that said something about not being able to read from a particular address of the memory and asked if I wanted to close the program. The program in question.........AMVO.exe

Is there a chance that I may be able to ever get it working again.
Please help. There is noway I can get it over to America to a Toshiba repair shop as I am in Africa, and there isn't any Toshiba dealer here.
Thanks

I'm having a similar (tho not exactly the same problem) with a friend's that I'm trying to fix. For mine however, I get no beeps, no post/bios -- nothing. One time it booted into windows, but hung. I've taken the memory, disk, CD all out, no POST beeps, nothing (internal or external monitor connected). I can't get anything to show up on the screen 99% of the time.

The user said the machine had behaved "slowly" over the last couple weeks, then just died. Now it's been like this for a few days -- nothing. Is there an internal BIOS type battery that if dead, would have this impact?? I don't want to pull the thing apart to find out if I don't have to.

Mike, This would lead me to believe that you dealing with a bad adapter or adapter connection. The unit will, if there is no power input from the adapter, continue to run from the battery until it is used up. Most people don't pay attention to the power on light until it is pointed out to them. The power connector in the laptop is known for having bad or broken connections. At any rate, that's where I'd start.

When I said "nothing", I didn't mean there wasn't any power -- I have the LEDs on -- so power is coming through the box. I get nothing at boot time, no beeps, no bios, no video (internal or external). Screen is just black -- like there's no video signal at all. The fan comes on for about 5 seconds and goes off, the disk drive light blinks like 2-3 times, then goes off and doesn't come back on. I know the drive and memory are good, I've popped them in other machines and got no problems.

Ok folks, here is the fix for your problem. Copy and past in a new browser if it does not open from here.

You are so right! I had forgotten about the solder problems with this board.

Interesting... while symptomatically this is EXACTLY what's happening, I couldn't get any different response from the machine when applying pressure/wiggling that chip as described in the article/link you provided. The machine is effectively dead, except the fan comes on, the disk light blinks once/twice, then no further activity, and disk light goes out. The only thing I see is the light on the power button, and the battery/plugged in light (depending on which source I use -- and there's no difference using either source).

Like I said, with everything out of the system, no POST beeps happen, nothing comes up on the monitor/video to help diagnose. My only recommendation to the owner is a new motherboard at this point, which unfortunately I don't think is a realistic option, since the machine was having other problems until this started -- they could be going to a rat-hole here, and end up with paying far more in parts than it's worth.

Any one else with ideas??

Mike,
What I try to do is way the cost of repair to the replacement cost of a like item. If it cost more to repair than 60% of the cost of replacement then I advise replacement. some folks want to stay with the repair anyway. you can check the replacement cost of most laptops on eBay by inputting the information you have in the subject line here. then check that against the repair costs. I'm thinking, like you, that it replacement time.
edit: spelling check not enough coffee.

Mike,
I see you said earlier that you do not want to take the laptop appart. There is no fix without taking it appart.

Since you have now reached the conclusion to replace the board and I kind of agree with you and Willie, I have my doughts that you will find another board on Ebay. I say that because all these laptops have the same problem. and you may not find a working board at a reasonable price.

I'm encouraged about this laptop because you said it booted once with you but gone dead after. Which in my opinion it is only a loose solder somewhere and it is a matter of time for you to find it.

Here is a last trick you can try that will give you a broader coverage at once but you can do it at your own risk. I do this for boards that I can't pinpoint the exact faulty solder.

First you need to take this board out of the laptop and disconnect all plastic connections from it. I mean ALL connections with no exceptions. Second, find yourself a good heat gun and while the heat gun is on, go over the video ship and other soldering arround it. the heat gun should be about an inch away and be generous with time. About 30 second or less). Make sure the board is seated flat and is not on an angle. Allow ample of time for the board to cool before you reconnect it back to the frame and re-assemble the laptop.

The idea is to melt the solder back and resolder all smal soldering that disconnected due to heat and time.

You have to stay away from the CPU base or any plastic like the memory slots or others or they will deform and you will not be able to use them again. Again you do this at your own risk.

In areas where plastic existed, I used a wet paper towel on them to protect them from excessive heat but remember you will be cooling one side only so it is a risk.

Good luck,
Mike

Lol,
I know you will.
I fixed a video card on a Toshiba that way in less than a minute. But I had to apoxy the borders so that it does not come out everagain. I think the board warp after a while with causes the solder to pop.
Cheers,
Mike

I have been shouting that for a long time. It happens most often with the BGA chips. Having worked in a factory where those things were attached to the board, I know it happens. The BGA should not be used with a thin mounting board.....ever! The stiffeners they install in laptops today don't do the job. Anyway, thanks for the tip. Mya your new year be the best ever.

Unfortunately, I don't have a heat gun, but that's an idea almost worth going out and finding one for. I appreciate the idea, it's a clever one for sure.

Thanks to everyone for their input on this. Happy New Year to all!

Mike
