AN515-58 Slow Charging

Hello,

I've been having issues with my laptop charging, and AN515-58. The supplied charger has become extremely loose and slips out. As such I've bought a 135w charger which plugs in fine and charges when not in use, but does not charge beyond light usage. The charging/power lights flash when gaming, and the power icon on the start bar shows it not charging.

I've taken the bottom off, the connector is soldered on and everything appears in place. I can't see any debris in the port.

I've tried 65w and 100w USB-C laptop chargers. Both show as slow charging, which I expected from the 65w one but not the 100w charger ( https://www.hp.com/ie-en/products/accessories/product-details/2103530906 ).

Any ideas on how I can fix this? I've tried the battery reset (there is no pinhole but I've held the power button down for 30s while unplugged), which hasn't changed things.

Thanks in advance
