SL – no driver for Win7? I really can’t find the Win7 driver for that thing. Under the “Details” Tab ACPI is power management.

The drivers for this device are not installed. X; Windows 7 bit.

I then reinstalled the PM driver and that other excl. When I try and find the driver it can’t be found. Any other idea, anyone, please?

SL – Unknown device problem in Device Manager – Lenovo Community

llenovo I don’t work for Lenovo. Take a look at our ThinkPads. I just found out that the driver you linked is a PM driver – I UNinstalled it and got another exclamation mark, so it’s not the driver for the unknow device I have problem with.

Thank you SO much for your time!!
