I turn on the power button on my laptop and it powers up. No Toshiba graphic appears, not even the backlight.
Thanks for making your site; it has some very useful information. Unfortunately I have an error for which I could not find a solution on your site.
I have an M35x-s149 Toshiba laptop. One day it started acting up… I turn on the power button, and the power management system powers up CD-ROM etc has sustainable power. However nothing appears on the screen. No Toshiba graphic appears, not even the backlight. Also the wireless internet connection will not activate, and finally I noticed where normally the green HD light would be blinking rapidly, it will now only blink a couple of times upon pressing the power button then cease to flash until I power off again.
I’ve tried plugging the laptop into an external monitor. No display. And I’ve checked the cooling fan outlet and it doesn’t appear to be clogged.
Any ideas what the problem might be? Is it a burned out hard drive? I would have thought at least the Toshiba graphic would appear if the HD was burnt out. Would appreciate any advice you might have.
You are right; it doesn’t look like a burned hard drive. When a hard drive goes bad, you still should get some video on the screen. I think that you might have a failed memory module. Very often a failed memory module causes a laptop not to boot with symptoms like yours – power LED lights normally, DVD powers up, hard drive LED flashes a couple times, but that’s it. Nothing will appear on the screen and the backlight will not light. If you have 2 memory modules, try to remove them one at a time. If you have only one memory module, try to reseat it. Try to move the memory module into a different slot, because the memory might be good but the memory slot on the system board has failed.

I had a similar problem with a Toshiba Satellite A300D-15B, I had just replaced the thermal unit (which is a heat sink for cpu and gpu and fan), put everything back together and rebooted.
The laptop just hanged, blank screen, on button back light on,
dvd-rw accessing you saw drive’s yellow light flash ever few seconds and so I read this after hunt for answer. I removed 2 memory modules of 2 gig each. Then inserted one in properly and switched on, the system rebooted prefect. The problem was the memory modules needed to be fitted properly. Thanks alot !!!!

I have a Compaq that is doing the same thing.. I just leave it sitting there, and sometimes the LCD will fire on after it sits there…I don’t even see a back light when its acting up. I assume that the inverter isn’t bad, because When I try the external Source, I still don’t get a picture.. Even if I totally reboot, and even with the FUNCTION Key, no Display. I checked the memory Modules, and It still had no affect on the display. I probably assume that its the on-board video chip. I hope not.. since that will require me to replace the mobo. Anything else I’m missing? Should I unplug all peripherals that are replaceable on the board itself?
Procedures performed:
Resetting the battery
Checking Memory one at a time..
External Monitor (both rebooting, and Function key)
Taking out Wifi Card (since it was bad to start with)
Took out the Hard Drive and restarted.

My toshiba satellite a100 started freeze a week ago. Usually it freezed after a couple of minutes after power on. And always after 2-3 minutes while playing videos. I ran all sort of antivirus and spybot, adaware etc. Everything seems to be ok. I thought it was a memory bank problem (it has 2 512 Mb banks), so I powered off and pull off 1 bank. The PC never booted again. I put the two banks again, but nothing. On power on, button light is on, small leds (AC and power switch) are on, cd driver seems to start, but nothing happens. Screen remains black. And that’s all. May anyone help me? Thank you. Armando.

Man i have a Toshiba Satellite M115-S3094 yesterday i was using it, i was in the toshiba website, they said getting the latest BIOS drivers was good to avoid future problems with battery. I installed the drivers with the ac adapter plugged in and it finished well and it restarted fine and continued working, i used the computer for a lot of hours then i turned it off AND PUT IT ON ITS BAG (which i think it was the main error) and now when i turn it on the blue light goes on, the CPU fan starts, it kinda beep on the speakers (like a tat, tat, tat sound) AND THE DVD DRIVE DOESN’T OPEN. i tried reseat the memory and put it on the other slot but nothing happen. From what i have read here it seems it could be either the mother board or the Ram memory i hope is not the mobo, and i hope i can get some help, thanks in advance……
