Ideapad Z510 low performance on battery mode

2014-11-13, 8:56 AM

Hi.

I have some issue with my Ideapad Z510.

When AC adapter is plugged in, everythink seems fine, and work properly.

Problem starts when i disable AC adapter form my komputer, then performance of it drasticly low. It doesnt matter that i have put my charge pan on high performance, every single options is on high performance and still its lagy and low. When i put AC adapter, everything back to normal. Dont know if its issue only by me ? or by this model ? how to chenge it to get full performance on battery ? i dont care than energy will be eaten very fast, it doesn matter. What matter for me is that i need to have full performance on battery, same as like on AC adapeter switche on.

 

Thank you for answer and help.

I have some info. I tested it. And what i found is:

When i put AC adapter in laptop i have full power, then i disable AC adapter and power is lost, then i chage power managin to low, and change again to high performance ... and what i get ? i get full power without AC adapter. Next i put AC adapter into laptop and disable it, and again...low power, and again i change in power management to low and to high...and again i get high without cable.

 

So what i can tell you ? Its not battery issue, because i can make it that it will work on battery on high performance. Its software problem.

 

Tell me how to repair it ? Becuase when i turn on laptop without AC adapter, it doesnt matter what i switch in power management, it will dont go on maks power, after plug in ac adapter, power is back, and now i can disable it and change managment to low and high performance and its ok.

 

Pls help :)

I think there is a bios update to address the issue, not too sure if it for that particular problem

Have a look at the read me file first before you install anything.

If you private message one the mods or Administrators they will send a link to v40 bios update. Apparently it has helped a few people so far, I tried it and the problem of being stuck at 0.77ghz has been solved, now I have another problem that my battery has died.
