I got a T530 ( not 20). My laptop says it's charging but the percentage isn't raising. I already bought a new battery but the problem persist. The new battery discharged( only when the Ac adapter wasn't plugged in )
Ac adapter: 90 W and 20 V

I messured the Volts with a mulitmeter as described in the comments, the result was 33 V
Hi there
I got a T530 ( not 20). My laptop says it's charging but the percentage isn't raising. I already bought a new battery but the problem persist. The new battery discharged( only when the Ac adapter wasn't plugged in )
Ac adapter: 90 W and 20 V
Lenovo 0A36303 Thinkpad Battery 70++ (9Cells, 8400mAh)
Should i buy a new AC adapter? When yes a stronger or the same one ?
Or is there a way to fix my AC adapter?
