So the basics.
Laptop only works off mains, battery is seated correctly. Even when there is no OS installed.
Laptop powers off as soon as charger is removed.
What I've tried:
Removed battery and held power button, usual 101 stuff.
I've replaced with genuine battery and still the same problem.
I've updated the bios to version 300
Installed windows 10 and shows as fully charged but of course if i remove AC then it turns off.
All hardware looks good.
Please any help much appreciated.
I've checked the motherboard and it looks like there is no damage, I'm pretty much at a loss. Any help would be much appreciated. Also I noticed when I ran battery care, it didn't pick up the battery details, it just said it had a couple of hours remaining. Its a really weird issue.
