I have DV9543cl Laptop and have been using it for a long time. I just replaced the mother board and reinstalled Vista.
I have 2 problems:
1. Once the laptop is awaken from the sleep mode, the keyboard works fine for a few second and then it hangs. No response (for example Caps lock light doesn't toggle and can't type with any keys). If i reboot then it works great.
-- I tried removing driver and let vista reinstall it but that's didn't work
-- Also tried going back to old NVIDIA driver but that didn't work either.
-- Device Manager --> Kayboard--> Properties -->Power Management has the "Allow this device to be turned off to save power" Grayed out.
-- Once I put the Laptop to Hibernate then the keyboard starts working back again.
2. The touch pad light lights up but it doesn't work
-- Tried installing Synaptic driver but didn't get installed.
-- In Control panel-> Mouse, i don't see any synaptic device.
- Vista 32
Any help would be greatly appreciated...
