I've looked around and had several friends have a look but we cannot figure this out.

I am running Ubuntu 12.10 on a Lenovo U310. The laptop charges fine when the laptop is off but it will not charge when Ubuntu is running. When I plug it in, acpi recognises that the charger is plugged in and charges for a second or two before going back to a state of discharging.

EDIT: The battery is definitely draining over time even if it is plugged in.

Here is the output for when acpi acknowledges that the charger is plugged in for a few seconds.

acpi -b -a Battery 0: Charging, 52%, charging at zero rate - will never fully charge. Adapter 0: on-line

EDIT 2: This could well be a hardware problem. I've made a fresh install of Windows 7 with correct drivers and I'm getting the same issue. I can run off of the A/C by disconnecting the battery so I know the adapter is fine.

Have you tested, to see if it is not charging, or just reporting that it is not charging? – richard Jan 21 at 13:36
If I leave the laptop on, it will die. The battery percentage has dropped 30% since this morning and its been plugged in all day. – Benji Hooper Jan 21 at 13:39
+1, Hope someone can help, I am just helping with making sure the question is clear. A second question that may help. Does it charge if when you boot you go into BIOS for an hour, or stay in the grub boot loader. – richard Jan 21 at 13:44
I will try this later. – Benji Hooper Jan 21 at 13:45
