Dell XPS 15 9550 Battery Not Charging

Jump to solution

I recently got my XPS 15 and was messing around with the BIOS settings for battery life.  I changed from the Adaptive mode to Custom charging, from around 80% to 90% thresholds.  When I booted up my machine, the battery indicator on the taskbar shows "plugged in, charging", but that clearly is not the case, as the battery life gradually decreases as if it is not charging at all.  Also, it no longer shows the estimated remaining time, but "Calculating...".  I tried reverting back to the Adaptive mode, but it still has the same problem.  I also installed the Dell Power Manager program to see if that helped things, but it hasn't.  

Has anyone else had this problem after changing the battery settings in BIOS, and how can I fix this?

My problem has been solved! Just let the battery run totally empty while keeping the laptop adapter plugged in.

After shutdown it will charge normally again!

...and if it doesn't (start charging) then I guess you are really in the 'do do..!'

That makes no sense how is the battery going to go down if the AC adapter connected to it??? I just updated to the latest bios yesterday and now my laptop wont charge more than  60%

In that case, you have a different problem than discussed in this thread. Our laptops were not charging at all even when the adapters were plugged in.

Method 3 - Reset BIOS defaults

A) Power off computer. Disconnect all external peripherals (flash drives, printers, external hard drives) from the computer.

B) Disconnect AC Adapter and then remove the battery from computer. Press "Power On" button for 15 seconds then release.

C) Replace battery and the AC Adapter. Power on system, hopefully battery is charging again

D) Power off computer and then power on computer again, quickly start tapping the F2 key continuously. You should be in the BIOS. Press F9 key to load BIOS defaults, press F10 key to save and exit. System will restart. Hopefully battery is charging to 100%.

Interesting solution until you state 'Remove the battery', does that mean physically dismantle the computer as the battery is not exchangeable it is integrated into the hardware......
