My Toshiba Satellite laptop will not power up

carsons2008 · 11-30-2008, 07:47 AM

I have a Toshiba Satellite L45-S7423. The motherboard went out on it back in September of this year and it was still under the first year warranty so the company fixed it. The warranty ran out on October 5, 2008 and this morning I get up and it will not power on again. This time is different than last time though. The battery charging indicator light is lit when it is plugged in but it won't do anything. Last time no lights would come on. I don't know what to do with it. Maybe I should just trash this one and buy a new one. If anyone has any advice on what I can do to bring the computer back up I would appreciate it.

I have already tried taking the battery out and waiting a few minutes to power it back up and that did not help.

Can you power it up on AC alone (battery removed)?

No it won't

I used it around 2am EST and then put it to sleep and now this morning nothing. I would hate to think that this mother board that was just put in around August/September has went bad.

So regardless on battery or AC adapter the laptop does not power ON. Everything is OFF... no lights, no beeps, no sound or anything? If this is the case then start with checking the ac adapter. Measure the output of the AC adapter. If output is OK, try stripping the laptop down to motherboard, LCD and power ON switch (remove everything else).

Not to bump this thread, but I have the same problem as the original poster. I have a Toshiba Satellite M55-S329 that will not power up. I was using it last night and it just went dead as if the battery was exhausted. In fact, shortly before that, the low battery alarm went off and I plugged in the ac adapter before it turned off. Before it died, there was no low battery alarm. Now when I attempt to turn the computer on, I have to hold the power button for a few seconds to get the light on the power button to turn on. It stays on for about ten seconds before going out. The power supply fan does not turn on and the screen is blank the whole time. I tried taking out the battery and running on ac, same thing happened. I checked the ac adapter output with a voltmeter and it checked good. There are four lights on the front left edge of the laptop: a battery indicator, an ac power indicator, a power on indicator, and one other that I'm not sure of, it has a cylinder symbol next to it, I believe it's a disk drive indicator of some sort. The battery and ac adapter lights are responsive: if I remove either, the corresponding lights go out, so the power supply is at least partially functional. Any help would be very appreciated.
