Removing battery from laptop

[ignoic]

I own an HP envy notebook and was wondering if it would be fine to remove the battery (dead, can’t hold a charge) and keep using the laptop batteryless? I heard that doing this to some specific laptop models could cause problems, so can anyone tell me if this would be fine for my model?

@ignoic,

Without your full model number being provided, we don't know if your model has a CMOS/RTC battery on the system board.

If it doesn't, every time you start/restart the system, you may see a 'CMOS Checksum' error and need to reset the date and time. If you don't reset the date, the Windows Update will eventually throw an error saying Windows cannot install updates because of a wrong date. Other than that, you should be able to use the notebook normally.

If you have a CMOS battery, CMOS and RTC clock will be powered by the little battery even when the laptop is powered off.

If you run the notebook without the main battery, a potentially serious problem is that a power outage can damage Windows, BIOS or hardware.
