power issue

[Repeter1]

My Probook 450 GS (Win11)  will immediately shut down  if I pull the ac adapter out. It has had the battery replaced a few months ago  but about a month ago this issue started. It would not boot unless plugged in. This went on for a week or so, then the issue corrected. Yesterday, it started again. We travel a lot and I'm wondering if a ribbon connector has shaken loose enough to cause this problem. Am I on the right track? I'm no tech but I don't mind pulling the back apart if it seems necessary. Ideas?

hello,

>>It has had the battery replaced a few months ago

(1) Original HP battery or third party ?

(2) Does the charging light is on the connected with ac adapter ?

(3) Does the charging light changes depending on the state of the battery ?

best regards

HP battery.
The power light is on when the adapter is plugged in.
No change in the power light. It is steady

When I try to boot the computer on battery only, the keyboard and power button will flash on and a couple of times, then nothing. Tried a scan dsk, it says their are corrupt files.
