No I actually don't. Should I buy another AC adapter to test it?

Thank you for the answer. The AC adaptor doesn't indicate the wattage on it. It comes with the laptop and It surprisingly a lot smaller than other AC adaptor I've seen. Yesterday the battery is staying at 54% the whole night even when I left it charge (status is plugged in, charging) I had to do a hard reset by unplug the battery and hold power button for 10 sec to actually get it working.

After couple complete shutdown and crash, I have found a little problem with my new Y400 (with GT 750m). I ran Heaven Benchmark with my laptop plugged in without battery (took it off the back) Right when Heaven Benchmark started running, it shutdown completely. Same thing with when I tried to play Hitman Absolution. However, when I put the battery back in (plugged in) it does not. I can't think of a reason why this happened. Anyone know the reason? I had it run Heaven Benchmark and the temp is around 60-65 with cooling pad underneath. Another problem is after an hour or two playing hitman absolution, I noticed a big drop in FPS and when I get out to window, I notice the battery status is 54% plugged in and not charging. I had to restart to get that status to change to "Charged". I had a gaming laptop before and I don't think it takes power from battery while plugged in. This one does which is a new thing for me. Is it what Y400 supposed to work or I have a hardware/software problem?
