Issue: power button worked after pressing too hard but now after getting it opened by a friend who wasn't competent at hardware issues , the POWERBUTTON does not work at all.
Steps taken to fix: reopen the laptop back and check that everyone was secure but can't figure out what the problem. I took it to the technician and he said power button is fine and something else is wrong.

Is it possible to buy replaceable parts for Toshiba L-40A.
Thank-you
 
Hi,

Here are some troubleshooting steps that I suggested to others who had the same concern that may help.
- Start by doing a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If this will not work, do test the AC adapter if it's working properly. Remove the battery and power the laptop with just the AC adapter connected and see if it will boot up or not. do also try a different AC adapter that has the same voltage and see if it will work or not.
- Proceed with reseating the RAM's if trying a different AC adapter will not work, remove them all for couple of seconds then put them back in making sure everything is seated properly.
- If it will still not work, connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem is the built in display.
- But if there's still no display on the external monitor that means the problem lies in the motherboard.
- Do also consider replacing the Power Button if you have determined before that it was working when you press on it really hard to power it on.
