won't come out of hibernation

[cigarsmoke]

Hi all, when done using the computer for the night I close the screen and disconnect from the power and let it stay in hibernation until the next day when I use it again. The last time it wouldn't come back out of hibernation, the power light is on but the screen is black and there is a light flashing on the side by the Ethernet cable port and then the caps lock button will flash once every few seconds. I tried to force power off and taking out the battery but when I turned it back on it immediately does the same thing. I tried getting into the diagnostics when starting but it won't let that either, it just instantly goes into the problem with the the light always flashing on side. If anyone can help me I would greatly appreciate it. Thank you all for any help.

Hi

Can you match the Flashes to anything in this document?

OR

First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

NOW begin checking/testing/proving the Hardware is fit for purpose.
Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

I tried holding down the power button and that didn't work. Thank you for the idea
