Whenever i plug my charger in, it says charging for a second, then reverts back to the battery. It used to only charge when it was off, so id have to shut down to get a full charge, then turn it on, use that power then shut down again and repeat. Now though, it wont charge at all, even when off.
The battery doesnt seem to be the problem because the laptop turns on for a second when the battery is unplugged.
The charger is working fine it seems as it is throwing out the correct voltage according to my multimeter.
The AC Jack has been replaced also but the problem persists. The charging pins on the part the AC Jack plugs in to the motherboard has the correct voltage on my multimeter also, so it cant be that.
This leaves me lost. Any suggestions would be greatly appreciated, I need this laptop for Uni work
When switched off, I plug in the charger and get an orange flashing battery light for a few seconds. It then switches to solid orange battery light and a solid white power light. It seems to be switching itself on and wasting any battery it had? Atleast thats what I can tell from the light guide I found. Although the screen and keyblard light don’t turn on when this happens. I dont know. They do turn on when the power button is pressed though for a split second before it shuts itself off.
Sorry if this makes no sense, i’m just trying to provide as much info as I can.

Thanks for using the Lenovo forums.
I would say try to see if you are able to use another charge, just in case.
Also, Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.
(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal
Hope this helps, let us know how you get on.
