After a Windows 10 update, I get nothing on the the screen whatsoever and no boot-up.
Initially I got three beeps.
I have tried: Stripping the laptop and taking out the CMOS battery and putting it back. The beeps went away, but still no screen, even after waiting 5 minutes and multiple powercycles.
I have also tried connecting an external monitor. There is only 1 second of hard drive activity when I power it up, then nothing.
I have read online that others have this problem.
