Fan starts then stops, no power, caps lock blinks slowly
Hi,
Model is X0Q77ES, 250GB SSD, Model 250 G5
What I’ve tried so far;
- Windows Key+B and Windows key+V BIOS and CMOS resets. Didn’t work, fan whirred then stopped, then caps lock blinks. Have to remove battery to stop this
- Created BIOS recovery USB from HP Support. Inserted in USB, tried turning on normally and then turning on with WK+B held down. Same result as previous
- Went through HP virtual assistance confirming AC adaptor works etc.
Have ended up fairly confident this is a major hardware fault and now requires investigation. On reading, I’ve picked up from various webpages that the ram or hard drive could be the problem.
Found a few answers in ifixit about rotating ram, gpu reset with hairdryer etc. etc, but nothing exactly the same as my issue, so figured I’d put this out there to the experienced users and ask for help.
I’ve been around computers a long time and happy to take things apart, but a novice with laptops and need some guidance for next steps please.
Thanks
Harvey
