Lenovo Energy Manager, Windows 10 Upgrade and Conservation Mode

I realized on Friday that the Lenovo Energy Manager on my Y50 was no longer working.

First, some words of clarification: I spend a few hours with my dear friend Google trying to find out haw to fix “battery saver.”  (Well, actually I was watching the Back to the Future trilogy on AMC, but I digress.)

Battery saver to me is how you keep the lifespan and capacity of your laptop’s batter in as good shape as possible. You know, not keeping the battery charged to 100% and overheating when plugged in.

I learned two things about this: (1) “Battery Saver” does not mean how to keep your laptop’s battery in good shape – it is how to keep you laptop going as long as possible and (2) I have no idea what others call my version of battery saver.

Anyway, after going through countless search results I found someone (and I cannot remember who to give credit, unfortunately) defined battery saver the same as I do.

The solution: Uninstall Lenovo’s Energy Manager and reinstall it! Simple, what?


If you upgrade a Lenovo Y50 from Windows 8.1 to Windows 10 you likely will need to uninstall Lenovo Energy Manager and reinstall it to have  “Conservation Mode” (which is what Lenovo calls my version of “battery saver”) actually work.

About Mike Pelley

Let’s see… A little about me… I’ve been around information technology since 1983 with computers such as DEC Rainbows (weird machine – the standard DOS couldn’t format its own floppy disks – remember them? – and I had to format them on a friend’s IBM PC) to Radio Shack TRS-80 to Apple ][e and Apple //c in the beginning. I have programmed in 8-bit assembly language on 6502, FORTRAN and COBOL on IBM System/370 (and I still hate JCL), VAX BASIC and COBOL (and a weird and massive WordPerfect 4.0 macro) on DEC VMS (Alpha), C/C++ on Digital Unix (ALPHA), and C/C++, Perl (it may be powerful but I still hate it), PHP on Linux (Red Hat, Centos, Ubuntu, etc.). I have work with databases such as Digital RDB (later to become Oracle RDB), Oracle DBMS, Microsoft SQL Server, MySQL and PostgreSQL on VAX, Alpha, Sun and Intel. Check out my professional profile and connect with me on LinkedIn. See http://lnkd.in/nhTRZe I still think that Digital created some of the best ideas in the world: VAX clustering, DSSI disks (forerunner to SCSI) and the Alpha processor (first commercial 64-bit processor – Red Hat screamed on an Alpha!). DEC just could not seem to be able to give air conditioners away to someone lost in the Sahara Desert! VMware is one of the best ways to get the most out of an x64 server. And I have tried Oracle VM, Virtual Box and Microsoft Virtual Server. Outside of that I am a huge military history buff starting in the early 20th century. I love Ford Mustangs (my ’87 Mustang GT was awesome) and if I had the money I would have a Porsche 928S4. If I had a lot of money I would have a Porsche 911 Turbo. I also play too much AmrA 3 Exile mod. Over 5,000+ hours... I have a wonderful son, Cameron. I have a long suffering (Do you really need all that computer junk?) wife, Paula. I live in Paradise, Newfoundland and Labrador.
