I recently restored a R51 (type 2883) laptop to factory default to re-deploy to a new user. However, as I found out when I tried to give this laptop to the new user, when this laptop is booted without an ac adapter (only on battery power) the windows login splash screen is not displayed and the mouse won't move. After this happens the splash screen will not display even with a power cord unless I reboot into safe mode, log in, and then reboot again with the AC power plugged in.
I updated the bios to the most current version and verified that Userinit (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon) is C:\Windows\System32\Userinit.exe. Is there anything else you can suggest to help?
Thank you for your time.
