HP Elitebook 840 G3 not seeing battery.

My laptop has stopped seeing the CS03XL battery.

Windows says battery status: 0% available (plugged in)

HP Support Assistant states that it can't find a battery.

I have tried removing the battery and then refitting it and that made no difference so I bought a new battery and that did not work either. Tried a third CS03XL battery and still windows and HP Support does not see the battery.

I have Googled it and tried all things like deleting battery drivers, hard laptop reset/reboot etc, nothing has worked.

Laptop only works now on mains ac power and does not charge the battery no matter what one I put in the laptop. If I pull out the power cable, the laptop turns instantly off as you would expect.

Does anyone have any ideas, really want to be able to get the laptop working on battery again.

Thanks.

l’ve got loads of 840 G3’s at work are you using HP original batteries or clones? It sounds like you might need a new main board so probably isn’t a cost effective repair. They are pretty unreliable models as they start to age I’ve had plenty fail at work, one set on fire as well.

Thanks. Tried another original and a 3rd party battery but same result. I agree I think it must be the charging circuit or similar. Time for a new laptop.
