I have a friend’s HP Pavilion dm4-3050us running Windows 7 Home Prem that does not recognize the onboard touchpad or keyboard in Windows, or the recovery environment.
Booting into MSDaRT, or a WinPE disc, I have the same problem. In BIOS, the keyboard works just fine. Attempting to boot to a linux live cd BSODs with the error code 0x7E, which in my experience usually means a bad hard drive. However, oboard diagnostics (which recognize the keyboard) and PC Doctor 7.5 (no problems there, either) find no hardware issues. :/
USB mice and keyboards have no problems, and virus scans inside and outside of Windows show everything as clean. Also, a full recovery did not fix the issue…
Any ideas?
Need more info?
Let me know…
Thanks,
