T400 notebook FN + F3, FN + F8 expired

After a few days, t400 can work.

However, it was suddenly found that FN + F2, FN + F3, FN + F8, and so on were all effective. After the press, there was no reflection.

Two days ago. Depressed!

The driver was reinstalled n times, including the hotkey driver. Restarted n times. Invalid.

Call customer service and say it must be a problem with the corresponding driver.

Update all drivers with system update. the problem persists.

Even more depressing!

I found that there was a problem in t61: If the Terminal Services Service is disabled, then, function keys such as FN + F2, FN + F3, FN + F7, and FN + F8 become invalid!

The t400 is in the same line as the t61!

This is true!

For security, I have always been used to disabling the Terminal Services Service and optimizing machine performance.

But I didn't think it would be related to hotkey! Faint!

The Terminal Services Service is started, and everything is normal.
