Re: T410i missing graphc device selection in BIOS after repair

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:

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

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

   - Windows does not recognize external monitors via VGA anymore

   - Linux crashes at moving windows with the nouveau driver and the proprietary driver also makes problems.

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?

Thanks a lot  for your help

Re: T420 keeps powering off after drying from spilled tea

Hi Ami,

Welcome to Lenovo Community Forums!

I’m sorry to hear that you spilled tea on your Lenovo ThinkPad T420 and the system keeps shutting down on its own.

I would suggest you to perform Flee Power – remove the battery and any other peripheral device connected to the computer. Hold the power button for 10-15 seconds and then connect the AC Adapter and battery and try to turn ON the computer.

Abrupt shutdowns normally occur due to overheating issue as chances of dust getting accumulated are high. First of all, I would suggest you to ensure that air vents are not blocked and there is a proper air flow. Also, check the speeds at which the fan is spinning. Start using compatible cooling pads which will help in the flow of cool air into the underside vents of the laptop.

Please refer the hardware maintenance manual which will shows you how to take perform disassembly of the system and where the components are located. 

Hope this helps!

Best regards,

Mithun.
