toshiba Satellite

I have a toshiba satellite here that i'm working on and the problem that I am having is that nothing comes on the screen when I boot it up. There are no blinking "num lock" or "caps lock" when I turn it on. an external monitor doesn't do anything. I do see lights from the keyboard when I hit "FN" , i thought maybe it was on a different screen mode but nothin. Caps lock doesn't light up either. I can't get to the bios. No beeps. Windows XP. Last thing that happened according to the user is that they were playing a game, which one? I don't know. Any ideas. BTW, anyone know how to clear the CMOS on a notebook? Thanks in advance.

Just remove the CMOS battery and leave it for about ten minutes. Put it back in again.
...dont know much about the screen problem though..

you may have a blown cpu or display card or even a dead mother board the only way to check is replace each part till it works but un like desktop computer parts the bits for laptops are very hard to get it may be best to send it to a toshiba repair center

I've never seen the clear CMOS jumper on a notebook like there I have on a desktop which is obviously easier to get to. I can't even find the compartment for getting to the battery. So from what it sounds like, you think the board is bad?

normaly the cmos battery is hiden under the modem card but it wont work with tosheba lap tops as a reset as the bios holds all date even if it has no power its a securty thing to stop you by passing the bios password if one is set as you dont get any bios beeps its most likley the mother board as ram cpu and vid card faults will give you a selection of beeps when you turn on the lap top

i am beleaving the mother board is damaged but with out looking at it on my work bench i cant say yes its bad but thats what the avalable evedence points to this is a list of bios error codes
POST Beeping Error General Codes

0 Beeps - Short, No power, Bad CPU/MB, Loose Peripherals
1 Beep - Everything is normal and Computer POSTed fine
1 Short Beep Then Nothing Happens - Disk drive related problem / Video card problem
1 Continuous Beeps, or 2 non-stop/short beeps  - Bad power supply
1 Long Beep, 1 Short Beep - Motherboard Problem
1 Long Beep, 2 Short Beeps - Video Problem
2 Beeps - POST/CMOS Error
3 Long Beeps - Keyboard Error
3 Short Beeps - Bad memory
Repeated Long Beeps - Memory Error
Continuous Hi-Lo Beeps - CPU Overheating

If no beeps are heard and no display is on the screen, its most likely the power supply.  Check for Keyboard lights or for hard drive/floppy drive lights.  If lights come on then power supply is good.

Next, inspect the motherboard for loose components. A loose or missing CPU, BIOS chip, Crystal Oscillator, or Chipset chip will cause the motherboard not to function.  If you get lights then it could be one of the I/O cards.  Try removing each card one at a time and restarting the computer. as its a lap top and you get lights on the key board and it dose not have any cards
it looks a lot like a mobo problam
unles some one has enterd the bios password wrong 9 times in 3 reboots (it reboots every 3rd wrong entry) in which case you are locked out and only a tosheba center can fix it as a new bios chip is requierd befor it will ever work
