Lenovo Y400 needs battery to game?

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?

Re: Lenovo Y400 needs battery to game?

hi Alankevis,

 

Thanks for using Lenovo Community Forums!

 

Have you check your Lenovo Energy Management Software,

   Try Launching it and check the Lenovo Energy Management

There is an option there for battery and make sure it is selected to Maximum Battery life or Optimize for Battery Runtime

 

The other option will limit and Stop charging beyond 60% and may show you the same error "Plugged in not charging".

 

Hope this helps,

Cheers!

Re: Lenovo Y400 needs battery to game?

After I cruise around the forum, I have found that thread about the Lenovo Power software. I have interchange between the two options. But I don't think that answer my problem about the drop in FPS. Why would playing game while plugged in takes up power from the battery. Also about the sudden drop in FPS like it doesn't have enough power from the AC to get the card running. 

 

Another problem appears no matter if I had Lenovo Management Software installed or not, it says "Plugged in, Charging" but the percentage stays at 54%. I left the Laptop idle for a while and it is still 54%. (switched from Maxium Battery to Optimize and vise versa)
