Yes, it will still be charged, to reset the bios password you need to locate the cmos battery on the motherboard and remove it for 10 mins or so, but where exactly the battery is situated, i'm not sure.

Forget my bios password notebook hp 6720s

Removing the RTC battery and leaving it uninstalled for 5 or more minutes causes all passwords and CMOS settings to be cleared. BIOS password can be removed by temporarily disconnecting/ removing the RTC/ CMOS (Coin-cell) battery from the motherboard. Disconnect the coin-cell battery from the system board and it will reset the BIOS to its default setting and the password would be gone.
Please Refer to Page 77 of the REPAIR MANUAL HP 6720S.
If you can't do it yourself, you may seek help from local laptop service professional.

GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

Need to know how to reset power on password for hp

If this is a BIOS Lockout Password, then you would need to Pull the CMOS battery From the laptop... Which most likely means Complete Disassembly of the laptop just to get to the battery... You would have to unplug the battery... Make sure the Laptops Charging Battery is also Removed and the AC Adapter is NOT plugged in...
Once the CMOS battery is removed, Hold the power button down for 30 seconds... then replace the battery and see if it is bypassed/removed..

There is a good chance that the BIOS password is on a security chip on the motherboard and if this is the case, then pulling the CMOS battery will do you no good... You will need to replace the motherboard if this is the case...

I have a Toshiba Satellite 1415-S173 with a bios password I don't know (original owner is deceased). How can I bypass or remove?

Remove the CMOS battery from the motherboard. Turn it over, open it up, and look for a little watch battery.
