Toshiba won't power on

[Artie_]

Hi, my Toshiba satellite was asleep and now it won't power on again. The power button flashes regularly, as does a white led on the edge and it makes a sound like it's going to boot. There's also a steady white led on the edge when the power cord is plugged in (it was orange minutes ago). I've tried the reset method to no success...

Hi,

It seems like the built in display isn't working. Here are some troubleshooting steps 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.
- 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 GPU.
