It would happen occasionaly , now can't get started. tried holding the power button and "d" and also the F12 key
I removed everything from the laptop, including battery. Far as I got was:
"Realtek PCIe GBEl Family series
PXE Media Test failure check cable
PSC-MOF exiting PXE rom
No boot device found. press any key to reboot."
ran out of time. did I lose my hard drive??
