I am running Windows 8 on my XPSL521x. Updated the BIOS from A09 to A15. After the update the battery status says that battery charging is disabled. I do not see an option to enable it.
Under battery health it says the battery is performing normally. I tried two different dell chargers and they both register in BIOS as 90W and charge my other dell laptop.
So I tried flashing the BIOs back to A09 and got an error message saying to reboot, try again, contact tech help, application error return 0x00000207.
Someone recommended that flashing BIOS back would not fix the problem and to replace the communication chip on the battery or charger but they both should be working. I had a similar issue with my last laptop, plugged in not charging, and flashing the BIOS back fixed the problem for several years.
I tried reformatting back to windows 7 with a dvd and it said that files are missing on my computer and I need to use a recovery disk. All I have is the windows 7 dvd.
What should I do to enable battery charging?
