Hi everyone, I think I might need some suggestions here on a problem I'm having with my office laptop, a HP250 G4. A few days ago I started having this issue: when I press the power button, the CPU fan skyrockets to it's speed limit for about 60s without any display on the screen, then shutdown itself.
Battery does not charge. Can't boot from battery only, the PC must be connected to the wall to power up.
* Trying with HP support suggestions to discharge the PC by holding down power button and so on. Nothing changed.
* Connecting the laptop to an external monitor.
* Moving RAM sticks. Leaving only one. Switching to a brand new ram stick which is working on any other laptops I have. Removing both (nothing changed, not even a sound).
* Removing the drive. Changing with another (both with a clean install or completely unformatted).
* Dust cleaning ..
* Resetting CMOS. Changed battery to a brand new one.
From time to time (two times, actually) the PC did actually boot into windows properly. It could reboot and be shutdown and booted again properly.. but when I unplugged the cord once, it refused to boot again for about a day. This happened the second time as well (after a lot of tries), but actually isn't happening again.
So.. suggestions?
