Hello there. I need help with my laptop Alienware 14.

I have problem with charging.

I plug in charger, laptop is plugged in for about 20seconds and then shows unplugged and working on battery, after 5 - 6 seconds turns back to plugged in.

Sometimes the laptop freeze for about 5seconds, fan going on maximum and after 5seconds works normal.

Charger is 180w.

I tried another charger just 45w, if problem  will be still same, and with 45w charger is not a problem, plugged in all time, but charger is too weak to charge battery.

I tried install fresh windows, but problem is still same.

Is problem with charger or something with hardware?

Battery is really bad, on 100% shows 1h 20min and after maybe 20mins laptop turn off due battery is discharged. So maybe the problem due to battery? But I dont think.

many thanks!
