Please I have been using my laptop for up to 3 years now and I just changed the battery because it's gone bad (my laptop switches off around 60%).

Now immediately after changing the battery, I'm getting the "CMOS CHECKSUM INVALID" error message. I have browsed, it's said my laptop main battery also serves as the CMOS battery. The guy that repaired the battery for me said I need to flash the laptop.

For now, I use F10>boot options>legacy support... to boot my system.

The guy changed my keyboard (island style), screen open/close hinges and battery. So he practically dismantled my system. Even my Bluetooth is no longer available, though I plan to use external one.

My laptop: HP Notebook - 17-by0104ng

Please I need help now. Thank you.
