Hi,
Does it go black when you plug it in even if the laptop is on your desktop screen already? Here are some troubleshooting steps you can try.
- Do a hard reset, remove the battery(if not built in) and AC adapter then press and hold the power button for 20 seconds then see if the same problem will persist.
- If these doesn't work, uninstall/reinstall "microsoft acpi-compliant control method battery" from Device Manager.
- Again if it will not solve the problem I would suggest taking it back to where you purchased it from.
