I have a laptop Lenovo G575. MS Windows works without any problems on it, but with Linux, it freezes during login or up to 10 minutes after power on. I have tried Ubuntu, Fedora 15 and 16, Fedora 16 KDE spin, Fedora 16 XFCE spin, openSUSE, Pinguy and possibly some other distro as well. XFCE power manager got SIGTRAP when XFCE session started. It works without any problem on AC cord or if battery is more than about 50-60% charged.

Edit: Fedora 16 KDE spin works a bit better, but it freezes unpredictably on login. Lower the battery, more often it happens.

Does it work better without the battery attached? –  Faheem Mitha Sep 2 '13 at 18:34

  • Did you try running it on single-user mode (also known as safe mode)?
  • If battery is removed works better?
  • Did you try any other module?

It might be helpful to use the acpi command line application to get info about the battery state, cpu temperature (acpi -t) or just all the info it provides (acpi -V) - I used this to diagnose an overheating problem on an Asus n1201 that caused it to lockup. –  sfyn Apr 17 at 15:08

This is probably caused by power saving functions in a graphics driver or other driver. This is only a guess though. Try installing a closed graphics driver and see if it works? Otherwise it may be an issue in kernel code or X.Org.

hard to say without more info. –  maniat1k Aug 28 '12 at 18:33
I can't add any more info, that computer is unfortunately dead. Something hardware is broken, being diagnosed. –  majTheHero Oct 16 '12 at 13:14
