It would help to know what model Latitude you have -- and whether the new battery is OEM, or third party -- and whether the system recognizes it.

The other question that needs an answer is whether the system recognizes the AC adapter (F2 at powerup to check).

ArnaudVa · Answer

it is an dell latitude 5400 (not chrome or chromebook, the regular one)

and the system recognize the battery but it is not OEM

and the AC is recognized by the laptop

and (bonus) the pc works without battery

That would mean the new battery is either faulty or incompatible -- contact the seller for a replacement or refund.

OEM batteries are available.

ArnaudVa · Answer

even if the battery is recognized and the error is the same with OEM battery (old)

If that's the case, it could also be a faulty system board, but I'd try another battery first due to the cost of replacing that part.

ArnaudVa · Answer

i'll try with an other OEM battery

Latitude
