battery problem

[Nigelb9]

• 15 month old laptop will not work on battery.
• Soon as you unplug the AC adapter the laptop either dies and switches off or locks up and screen freezes
• Have installed fresh copy of Windows 11 and have performed battery calibration 
• Hp diag software shows no hardware error but quite obviously the laptop is faulty.

HP Diag will not report any fault doing a battery test and have also spent a whole day calibrating the battery, it is a hardware fault even though HP Diags reports no fault.

Hello @Nigelb9 

Battery looks good, please test and report back.

As I said in my original post, Laptop will not work on battery and still will not work on battery.

Power on the laptop on AC, boot into windows, everything works fine. Disconnect AC to switch to battery and laptop instantly dies and switches off.

Power on laptop on battery only, boots to windows desktop then dies and switches off.

Hello @Nigelb9 

The motherboard is defective because it does not recognize the battery voltage.

HP warranty expired:

You should have it serviced by a professional notebook (chip level) repair store.

Alternative:

If it can't be repaired or replacing the motherboard is too expensive, you should buy another notebook.

Good luck
