HP 250 G7 - Battery Issue (Lid behaviour)

[Federause]

Hi everyone,
I have an HP 250 G7 for assistance. I've changed the battery (the old was dead) with a not-original.
It has a particular behaviour that I've never seen:
With the lid open, the voltage is present on the relative pins. Upon a time I close the lid, after 5-10 sec. the voltage drops down to 0. If I re-open the lid, the battery keeps stuck in this situation. I have to connect the power supply to "resurrect" the battery. In this way, I can power on the laptop without any problem and also use it without the power cord. If i shutdown the laptop, keeps it with the lid open and try to power up, it works perfectly.
I've tried with another old original battery that I have (with a different code but it's compatible) and the behaviour is similar, with the difference that if i re-open the lid without the power cord, the voltage rise up without any problem.
It looks like the new battery has a sort of strange protection behaviour, i'm in contact with the seller but I don't trust their tecnhical skills...

MB model: EPK50 LA-G07DP Rev: 3.0
BIOS updated to the last revision (48)

Anyone could advice me other tests that I can perform?

Thanks a lot for your support

Test the voltage to ground of +3V_LID when the lid is open and also when it is closed.

- Lid Open
- Charger plugged in
- +3V_LID_R -> 3.35V

After that, removing the charger with lid open: +3V_LID_R -> 3.3V

Closing the lid without charger: +3V_LID_R -> 3.23V. After 5 sec., drops to 0.8V decreasing slowly to 0.

With lid closed and charger connected: +3V_LID_R -> 3.28V. After 5 sec. drops to 0.8 decreasing slowly to 0. But in this case, after other 5 sec., the voltage rises up to 3.28V but after 5 sec. holds fixed to 0.

SOLVED! It was a battery issue. I've changed it with another brand not-original and now it's working perfectly.
Thanks for your support mon2
