SL510 On Screen Display Issues

[ Edited ]

I have an SL510.  I installed Windows 7 Ultimate 64 Bit on it and am only having two issues, but i believe the are related.


I cannot get my on screen display to work (even after mutiple attempts at reinstalling/removing/reinstalling) the Hotkey Features software.


I ran the Hotkey Features Patch with no luck also.


In my device manager, theres one item (Unknown Device) that i cannot seem to find the correct driver for.


Hardware ID= ACPI/IMB0068


Please help,




Any help please?!?!?!  Any Lenovo employees out there?

Re: SL510 On Screen Display Issues

hey mylegitches,


for the on screeen display, try uninstalling the Hotkey and Power Manager software. restart your unit, download both software from our support site and reinstall.


as got the unknown device, could you post a screenshot of it here ?  Though looking at the ACPI part, I do recommend checking the version of the BIOS that you have.


currently the SL510's latest BIOS is version 1.47/1.03

I am uninstalling the Power Manager and the hotkeys now.  I am going to do a bios update before i reinstall my hotkey and power manager.  will repost results later.  i am remoting into my system from work so i cannot check my bios version yet, but the registry shows a date of 08/06/2010, so i am assuming there is a newer version.  when i get home i will update the bios.


Thanks for the response.  I'll be in touch.
