I have a toshiba laptop satellite L-300 that won't turn on. I tried unplugging AC and remove the battery and hold the power button for 30 sec. and plugged the AC back, i can see the green light at the front but the screen is still black, then I put the battery back on and the green light and the orange light comes on but the screen is still black and then after 2 sec, all lights shuts off.

check power cord is fully inserted into laptop
if no joy
try also forcing a power down by holding in the power button for 30 seconds and then try power button again to power it up .

might be in hibernate mode !

if you have warranty pls send it to service center you can quickly resolve the problem, if not pls check without battery and remove other parts and try

- remove the battery of your laptop
- unplug the ac adapter
- hold the power button for 20 seconds to drain the remaining power
- try to turn it on and try to type

Remove the battery and check the voltage on the battery, if low try to JUMP charge, if not replace. Also check the charging voltage with the adaptor connected to the latptop. If there is no voltage then the charger must be checked.
However if the battery and adapter seems good then the mother board is a suspect and it is ideal to get the help of Tosibha service for estimation.

I assume there is a specific reason that you mentioned the DVD drive won't open. Is it because there is a disk in it that you are trying to remove, and you can't because the laptop won't boot? You can open the DVD drive with a pin or paperclip. There is a little hole in the drive near the eject or open button. Insert a small pin or paperclip straight into that hole and push. It should pop open.

Hi,

I think you can try this step and see if it makes your laptop work.

1. Unplug the AC adapter and Remove the Battery
2. Press and Hold the Power Button for 30 secs. without the battery and ac adapter
3. Put it all back in and see if the machine will work.

If happened that its not working It could be one of the Hardware that's having a problem. It could be the Memory, Hard Drive, CPU or the Motherboard. Hope it helps.

Hello,

You may try this. Unplug ac adapter and remove the battery out. While the laptop is off and without the power sources, hold the power button 10 secs. Put the power sources back and turn it ON.

Check the power adaptor led is not flashing. Flashing Adaptor LED indicates fault with laptop charging circuit / powerboard

If it will not boot on battery, and you know the adaptor to be good, the issue lies with the motherboard.
Sometimes, removing the battery, and unplugging, pressing the power button and holding it for 30 secs, replacing the adaptor only will allow it to boot up, but this will only work if the motherboard is not damaged r the CPU fan has not failed.

remove the battery, unplug the ac adapter and press and hold the power button for about 15-20 sec to drain power. expect no response since we're just draining the power. then put back in the battery and ac, and try to turn pc on. if nothing works, update your BIOS.

do a power reset on the computer. turn off the computer. remove the battery pack and unplug the ac adapter. press and hold the power button for 10 secs without any power source to drain all excess power in the laptop. put in the battery first followed by the ac adapter. turn the computer.

i hope this helps.
