I have a ASUS K701C-A1 computer. When it is plugged in the battery icon on the lower right screen shows that it is in A/C mode but the charge light only goes up and down a few times then stops. The light at the center front stays red even when battery does not appear to be charging by the light moving up and down. It then says it is charge fully in a very very short period of time, meaning the little battery icon shows lit all the way to the top. After we think it is fully charged we unplug it and begin using it. It soon, 1/2 hour, says that there is only 7% of the battery left. We bought a new battery and installed it today and it does that same thing. not sure how to test what the problem is.
Got any ideas? Power jack? connection between power jack and battery? bad power cord? How do I check these things? Thanks
