HP Recommended

Recently, I replaced my HP Laptop battery. However, despite it being fully charged, I can only switch on the laptop when I connected it with an external power source. Meaning, the laptop did not turn on when it was not connected to the charger.

 

When the laptop was turned on, a “CMOS Checksum Invalid” message appeared — and it happened almost every time I turned on the laptop. 

Could someone help me with this?
Thanks!
