I have a user that is having issues with there laptop not turning on, and I think its either the battery or the power I/C chip.
When the laptop has the battery in and is connected to the mains, the laptop will not turn on at all, however if I remove the battery and connect purely to the mains then the laptop boots fine.
I have tried removing the battery and pressing the power button for 30seconds, but this has had no results.
The laptop is only a few months old, so I just wanted a second opinion on the issue.
Thanks in advance.

If this is for an X280, as the heading indicates, the battery is internal and cannot be removed by anyone but a qualified tech. If an X280 will not even acknowledge AC power when connected (red dot over I in Thinkpad" blinks three times), disconnect from AC and take a paperclip and press into the pinhole at the back right of the bottom and hold for a few seconds. That accesses the "reset" button. After releasing, reconnect AC and see if you get the three blinks. If you do, let the computer sit for a half hour or so to build up a charge in the battery, then try booting. If this fails, time to call service.
