Lenovo Ideapad Z510 - Weak Battery Problem - FIX

Lenovo Ideapad Z510 . I own that laptop. Its great for many things but falls on the short end when it comes to battery. Not only the battery life was sucky, after about 1 and a half years of use, the battery suddenly started showing unusual behavior.

Has this ever happened to you?

  • Battery shows 100% then suddenly its 70% in a short time
  • Wait a little bit more and it whittles down to 12% or lower
  • And without any warning, the laptop just shuts off at one point
  • I know
  • I dealt with this shit for a while too
I was about to change the battery as it kept showing "Weak Battery! Please replace it" type of messages as pop-ups in my laptop. I would have probably changed the battery if it hadn't rained that day. 

So I went lazy and did had one of these moments:


You have to download these two things
What you should do?
  • Uninstall your previous Energy Manager software (likely version which comes bundles with Lenovo CD while purchasing)
  • Install THAT new version you just downloaded
  • Now then restart
  • If any problems occurs or any new error messages pop up; restart once more(those are traces of the old Energy Manager tool)
  • Now thats out of the way, use the Battery Firmware tool that you just downloaded. (First Extract all from Zip and install. Don't directly try to run setup from inside the ZIP duh!)
  • One restart and you should start seeing some magic!
  • Goodluck!! -- not that you need this; it absolutely works! ;)
