HP OMEN 25L GT12-0235se will not turn on

[Kepler29]

Purchased new HP Omen 25L in Aug, 2020. Its been in the original box and never set up until recently. The computer seemed to work fine for a week. Today the computer shut off unexpectedly and will not turn back on.  I tried disconnecting the power supply for ten seconds. I reconnected the power cord and held down the power button down for one minute, but still the computer will not turn on. On the back of the computer where the ethernet cord is attached there is solid green light on as well as a flashing red light on. Any help with would be appreciated.

Hi @Kepler29,

I am guessing: your monitor is good, the cabling is good, and you are making the correct connection from the PC to the monitor.

Ouch, it is difficult to troubleshoot a hardware problem in a forum.. It may cost some money to fix as you are probably out of warranty. You should contact HP Support if you have an extended warranty.

It sounds like a hardware problem. Did your PC update to W11? This can sometimes cause issues similar to a hardware problem.

You need to troubleshoot components to find the bad part. I can provide troubleshooting options if you want to do this. This process is time consuming, tedious, and requires known, good replacement components. It is usually less expensive to have a local PC tech diagnose the problem. The tech has the replacement parts needed to find the bad component if this is the problem.

I would first replace the CR2032 MB battery. This action is inexpensive and will also reset CMOS. Try to start the PC.

You can also visually inspect the MB for damage. Reseat all connections and components to see if you have a simple issue.
