Ok, its probably been asked before and answered but my searching skills arent 100%.
I have a Pavilion 15-CW1063WM and the battery has bulged in it, mostly due to it having been on mains all the time. Can the battery be removed and it still run on mains power without a battery inserted?
It will work but with internal batteries the system also uses it as a clock/CMOS battery to keep system time and maintain settings. If there is not a working battery, then any time you take power away the time will go back to the default date and all BIOS settings will be lost. You really need a working battery and you need to take out the bulging one before it wrecks the casing of the laptop.
