Thinkpads Forum

Hello everybody,

my Thinkpad t410i had an overheating problem so I gave it to a certified Lenovo store and they changed the mainboard.

After the replacement I am facing now two new problems:

The graphic device selection in BIOS/Config/Display is missing. BIOS version is the newest (1.45)

Both OS (Ubuntu 13.10 and Windows 7) have Problems with the graphic

Windows does not recognize external monitors via VGA anymore

Ubuntu crashes while moving windows if the free nouveau driver is in use
The docking station often does not recognize mouse and external monitor
If the proprietary nVidia driver is used Ubuntu often gets super slow and crashes after waking up from suspend

Does a hardware replacement has an effect on running os and could require a new os install?

When is the graphic device selection in BIOS/Config/Display available and when not? Why is it missing now?

Any way to fix this?

Do you need more info?

Need the laptop for work and writing my bachelor thesis and don't know what to do at the moment

Thanks a lot for your help

The Model is a 2518-A3G

Information from BIOS:

BIOS Version: 1.45 (6IET85WW)
BIOS Date: 2013-02-14
Embedded Controller Version 1.18
Machine Type Model 2518A3G

The system board FRU after the repair is now : 04w0509
but according to the Lenovo system service parts FRU for the 2518-A3G it should be: 75Y4146

Which system boards are compatible with the 2518-A3G?

And which support the BIOS Optimus option and which the Switchable BIOS option?

Somebody has an idea? would be so great!

Thanks!
