IN sleep mode or somaerhing

[markp35]

I have a toshiba satellite lap top L655D-S5066 that has stop working or is in a sleep mode. I have tried every thing that has been discussed on this site and nothing works. I have taken the battery out , held on off button down for over 30 seconds several times and it does nothing. I can hear I guess the fan running but very slow. I have NO screen that pulls up at all. The three lights on front are all white. Have plugged power cord in and out several times too but nothing happens. I need HELP!!!

Hi,

Please do try these troubleshooting steps that may help in solving the issue.
- Start with a hard reboot, remove the battery and unplug it's AC adapter then press and hold the power button for 20 seconds then try booting it.
- If it doesn't work reseat the RAM, remove them all for couple of second then put them back in making sure everything is seated properly.
- Again if these doesn't work but you can hear the laptop on but with no display, connect an external monitor and see if it would display anything because if it does that means it's the built in display that is faulty.
- Next to try is if your AC adapter is still okay by trying another AC adapter that has the same voltage and see if it would work.
- If all these will not work it would be a motherboard problem.
