Product: 15-da0327TU
Operating System: Microsoft Windows 10 (64-bit)

 HP Laptop   Model:15-da0327TU

 

My main battery was replaced with new one. There after I am having following problems:

1. Laptop does not starts without power adapter connected , though for a fraction of second. Once power on the adapter can be disconnected.

2. After power on a message appears

" This CMOS ckeck sum is invalid. The CMOS will be reset to default configuration.

   CMOS Reset (502)

Enter- Reboot the system"

After 15 seconds the pc starts booting and Windows loads. There after PC runs smoothly. Date & time showing in right hand bottom remains correct.

Is it possible some wire to CMOS from main battery left unconnected by the repairer ?

I will be grateful  if some wise man will answer my question and provide step by step resolution.

 

Thanks
