My Toshiba laptop just beeps when powered on

Try Resetting the CMOS on your Motherboard.
Turn off the Laptop and unplug it
Remove the battery
undo the RAM cover
Remove the RAM
plug the laptop into the power
Turn the PC on and listen for some beeping noises
If you hear the beeping noises turn the laptop back off
Unplug the charger
Replace the RAM into the RAM slots
Replace the the battery
Plug in the laptop and power it up.

if you get video output, that's Great, if not, it's possible that you have a faulty screen

NUMBER LOCK
You have press the NumLk key (number lock) and this changesthe right hand keys to a number pad.
Press the NumLk key (also doubles as the ScrLk key to toggle the Number lock).it is near the F12 function key. When the NumLk has been enabled a LED light is turn on to indicatethis function has been selected.Press the NumLkkey again to turn off the Number Lock.

I'm thinking the memory is bad, regardless of which slot you put it in.

video card or chip get run out or replace the ram

possibly ur display chip or graphic chip faulty. repair it from laptop repair prof.

If there are 3 beeps when you power on, most probable it is because of the memory.
Steps for Troubleshooting

Note:remove any source of power first ...

1. Try removing the memory
2. Clean the memory using a white pencil eraser
3. Boot up the laptop without the memory
- You will hear a beep not like the 3 beeps you heard.
4. Turn off the computer again and put back the memory.
5. Then try booting up again.

Hope it helps.

It indicates a hardware problem, check in your owners your laptops bios manufacturer and reffer to the list of beep codes ( http://www.computerhope.com/beep.htm ) to find out which part is damaged.

listen to the beep heres some information on beep code errors
Beep Code: Description of Problem: No Beeps Short, No power, Bad CPU/MB, Loose Peripherals One Beep Everything is normal and Computer POSTed fine Two Beeps POST/CMOS Error One Long Beep, One Short Beep Motherboard Problem One Long Beep, Two Short Beeps Video Problem One Long Beep, Three Short Beeps Video Problem Three Long Beeps Keyboard Error Repeated Long Beeps Memory Error Continuous Hi-Lo Beeps CPU Overheating

Remove the 1 gig chip. Pull you battery out and unplug the laptop. Hold the power button in for 10 seconds. Put the battery back in and plug the laptop back in again and try booting it up. This should reset the BIOS and allow it to boot. The beep codes you are talking about are a memory beep code and it is normally caused by adding memory or a loose memory stick. Also try pulling the existing memory and resetting it.

Thats a link to info about bios updates on the tosh website. If you're not getting to the toshiba screen then POST has not completed which means that either there's a hardware problem or the bios is corupt. If you're sure the RAM is ok try flashing the Bios.

Problem is though, to make the bios update disc, you need a working computer.

and, err, It'll probably have to be a toshiba!
(sorry, not my fault!)
