HP Pavilion Notebook - 15-ab035ax
Microsoft Windows 10 (64-bit)

Laptop doesn't boot without battery on direct power supply. 

HP hardware diagnostic test results on different components:

Battery diagnostic - 

  • Battery status: OK(0)
  • Logic state: OK(0)
  • Charge state: OK(0)
  • Failure ID: OK(0)



AC Adaptor test: PASSED



System board check: PASSED


Charging port test: PASSED


#1. Though, battery is replaced about an year ago. Still, battery doesn't hold/catches charge but power indicator light (yellow/charging). This problem is there on and off since before replacing the battery ie. since mid 2020, now it's more often.


#2. Without battery in place, system doesn't boot nor does the power indicator light. It just blinks once for a second when charger is plugged in.


I consulted technician, they looked into and told at first there was some problem with mother board and they have fixed it. System worked fine for a day and again the same problem. I consulted again and they told now it will work fine and it worked but for just one day or one charge cycle. I consulted again, and this time they told there is no problem in the system, I have checked it all. It is working fine here (2 days), so there may be fault in your charger. Hence, I bought a new genuine charger. Still, the problem persist.

Now, they have no answer nor am I able figure out anything.


So please help me or advice me what should I do now.
