Talk:Lenovo ThinkPad Edge E330

From ArchWiki

How much ram is usable after upgrading to 8 GiB? I own an E330 as well and i can only access 3.2 GiB on arch64 using UEFI (legacy bios completely disabled). can you post the output of dmesg | grep -i memory ?

No problems here. But I'm using legacy BIOS and old style partitions.


-- Many thanks for the information! You are missing 1 GB of ram because of memory mapped IO just like me. The E320 does not have this problem.

By the way hibernate works here (edit grub cmdline, edit mkinicpio.conf as explained in the wiki)


For memory mapping see there at that page the comment at the buttom: http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS029304

The WLAN card seems to be a very cheep model. I guess we can replace it with a Intel Centrino 6300 module allowing 450MBit/s but loosing Bluetooth. There are rumours some bios prevent such an upgrade though.

Afair my model has Bios 1.12 version. Not sure if an update to 1.14 is possible. That FreeDos model seems pretty strange and not widely sold. -- My notebook doesn't switch off its display using xscreensaver going into plain black mode. Is there any additional settings required to make it properly use DPMS?

DPMS usage was set to Flase in ~/.xscreensaver. Works well now after changing it manually to True.

backlight issues with kernel 3.19

I can't get 3.19 to work well with backlight control. The only way to make it poorly work is to apply acpi_osi="!Windows 2012" to the kernel boot parameters and keep thinkpad_acpi module blacklisted. Anyone with a good solution? https://bugzilla.kernel.org/show_bug.cgi?id=94561
