I have the same problem with the Dell Studio 1558, only with the i3 processor and the integrated Intel Video.
============ Dell Studio 1558 Intel(R) Core(TM) i3 CPU BIOS version: A11 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18) Ubuntu Maverick 10.10 Linux 2.6.35-22-generic #35-Ubuntu x86_64 GNU/Linux =============== I updated the BIOS from the A08 to the A11 version, it continued to freeze, stops responding completely. Tried several other workarounds, none worked. Will try to get a older kernel or disabling acpi and report on the results. -- System freezes when running on battery https://bugs.launchpad.net/bugs/662998 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
