I have a Lenovo U260 that is only a month old. The first OS I used on it after immediately wiping Windows was 32bit Ubuntu 10.10, mostly because that was what I had been using for some time on my last machine. Eventually I decided to re-install Ubuntu, this time with 64bit 11.10. After doing this, I noticed that the battery was not charging all the way to 100%, only to about 80%.
Lenovo practiced restraint with Lenovo Ideapad Z360 and its other Ideapad siblings. One of the more useful ones preinstalled with the laptop I make use of regularly is the Lenovo Energy Management Software.
For other reasons (mostly because I missed Gnome) I am now using 64bit Linux Mint 'Lisa', which I like very much, by the way. However, I have noticed that the issue with the battery only charging to 80% is the same. I have done a little searching here and in other forums and have not discovered this issue mentioned anywhere else, probably because there aren't too many people reporting on using this particular laptop with linux. In any case, I thought I would put this out there to see if there are any others who may know about this issue, or who may have ideas about its cause.
Code: present: yes capacity state: ok charging state: charged present rate: 0 mW remaining capacity: 29570 mWh present voltage: 15939 mV I can see that the (charged) state 29570 mWh is 80% of the last full capacity reported above 36970 mWh. The user that reported the bug later recommends booting into Windows and disabling Battery care as a workaround, which is not a possibility for me on my single-boot machine. My laptop did ship with Windows, however, so I suspect there is some information left over from when it was used that is now being reported to linux. My goal now is to discover where this information is stored and how to change it. Are you sure that using Ubuntu/Linux Mint with power regression issues has not already damaged your battery, reducing its capacity down to 80%? Such damage is one of the issues caused. When experiencing the power regression issue on my x121e I read somewhere about a user experiencing 50% drop in capacity when using a cheap replacement battery.
But.your power management setting sounds more plausible. In relation to the newer kernel, this power regression issue is not going to be fixed until kernel 3.3 which will be out in a few months (it is already in testing it seems from the ubuntu kernel server).
Hi Fellow Lenovo user here (Lenovo G570). It sounds like the energy management software locked your battery charging. The only thing to do is to re-install windows and the energy management software (hope you did a backup of the Software partition your laptop probably came with) and uncheck the energy management feature. It's strange though, mint 12 and ubuntu 11.04 detected the battery as 'Sony' models. I enabled the 'force apsm=true' option in grub, and in mint 12, i have around 5 hours from 100% charge. Strangely though, ubuntu 11.04 used to show it at 7 hours remaining!!! Don't know how accurate that was.
What kind of battery life are you getting from your laptop? Dsiarchith wrote:It sounds like the energy management software locked your battery charging.

I very unfortunately did not make a back-up of the software partition that my laptop cam with. However, I have some new evidence that may mean that that energy management is not the issue. I now have a maximum charge level not of 80%, but of 76%. I am now leaning more toward a power regression issue and wondering if I should be using Linux kernal version 3.2.
If it's a sandy bridge with hd graphics it's dead shure you are affected by the 2 power regressions that were introduced by changing the allowed CPU/GPU/chipset power states due to bug reports. These changes came with kernel 2.6.38 and 3.0. It's easy to revert these changes and to carry out a test. But I'm somewhat tired now repeating this over and over like a mantra. (just search my postings) I even told ddaann how to cure it but he didn't hear. This again was a small motivation.
So here we go: At the grub menu press and navigate to the line with splash (or nosplash) and insert pcieaspm=force and i915.i915enablerc6=1 Then boot with If it works as expected and no system instablity occurs (there's only a small risk) then make these changes permanent: gksu gedit /etc/default/grub find the line with GRUBCMDLINELINUXDEFAULT='quiet splash' and insert the above mentioned parameters. Save and exit sudo update-grub I run my Thinkpad X220 since some time like this and it needs only 5 W when idling, giving me 5 to 8 hours on battery. Nice One ej64. I couldn't get my head round the edits when you first mentioned them to me. I wasn't confident enough to try them. Now, having edited grub for my resolution (no success though) I'm more confident.
But will remain with Mint 11 until the kernel is out probably. On another note ej64, would you have any advice for my ongoing screen resolution problem that I have posted variously around the forum and web? Sorry for hijacking this post for my own ends but the suggestions I have been given have not worked and I've ended up in a bit of an impasse.

Any suggestions? Ddaann wrote:It should be 1366x768, but that option has disappeared, xrandr does not work, and editing vga=844 in grub makes no difference. Well, perhaps I've been lucky. Initially I had a similar issue and vga=844 worked miraculously, though I think in the meantime this parameter only sets the framebuffer size for the text console. Somewhat later I observed I didn't need the parameter any more.
Perhaps this had to do with a newer kernel (I'm using 3.1.8 atm) but I never went into detail. I would try to create xorg.conf with a modeline like this (from my system).
I have the a Lenovo Y 40-70. I've upgraded to Windows 10 and I need the 'Lenovo Energy Management' program in order to fix the battery gauge, which is giving me inaccurate readings (battery dies when it's showing between 30-40%) On the Y 40-70's support page, the Energy Management driver for Windows 10 is some sort of corrupt file, only 1mb and it wont open. Any idea what's going on? The link to the faulty download file is here: I know my battery gauge problem has to do with a driver in the device manager called 'Lenovo ACPI-Compliant Virtual Power Controller.' Sadly I haven't found a way to disable this thing in Windows 10.
If Lenovo has an incompatible driver on their systems, the least they can do is provide software for Windows 10 that will remedy the situation. They've got me running in circles. I have a Lenovo Y40-70. Same as obesechipmunk, I've upgrades to windows 10, and the battery gauge is also giving me inaccurate reading of the battery.
My battery is stuck at 8% when plugged in, and it estimates 10 hrs to fully charged. The laptop doens't seem to configure with the battery. I tried uninstalling Lenovo ACPI-Compliant Virtual Power Controller and reinstalling, but it doesn't work. I updated my energy mangament using the following link: However, it doesn't seem to fix the problem.
This is very upsetting. My warranty just expired for 1 month.
