New Laptop Battery Error

[hustle1]

Hello All,

I ordered a replacement battery for my 1040 G4 but all 3 new batteries report this error or Blown fuse.

 

I ordered the battereies from iFixit and from the first battery I installed had this error and it refused to calibarite on bios then would randomly Hard shut down whether plugged in or on battery.

The computer would also run very very slow, run on AC only and refuse to charge the battery. Only charge if I reset the battery by holding down Power button.

I reached out to iFixit and quickly got a replacement 2nd battery still same error.

Got another replacement 3rd  battery same error.

Only original battery is working, which I realized HP Support assistant/hardware diagnsotics was reporting as weak 27% capacity left but that was with the maximize battery life setting, with that off it jumps to 70% capacity but out of nowhere reports critical battery failure on bios but next day its okay.

All hardware diagnostics show no error with original battery and works fine even holds charge for 3 hrs. 

The weak capacity error on HP support Assintant made me order the replacement  but as you can see below orginal battery is now normal.

iFixit were great and gave me a full refund but I still dont know whats causing this issue? Is it battery or PC or HP software?

The Diagnostic error code translates to error code 601.

I recommend that you run the Windows Battery-report and then we can use it as part of the troubleshooting. Have you updated to the latest BIOS?

I explain how to access it in the knowlegeBase Article at the hyperlink below.

I just saw your PM.

In this case the issue is likely to be the resistor which acts as a fuse on the notebook's system board  in the power section or a possible failure of the the power management chip which regulates battery charging and switching between AC adapter power and the battery.

So I would have to have the PC system board repaired?

If you haven't done it already, try updating to the latest BIOS first.

If that fails to resolve the issue, then it is definitely time for your notebook to ho to the shop for repairs.
