The laptop I am dealing with is a lenovo y50:
- Intel Core i7-4710HQ
- 16.0GB PC3-12800 DDR3L SDRAM 1600 MHz
- 512 GB SSD
- NVIDIA GeForce GTX 860M 4GB Graphics Card
- Windows 8.1
A few days ago I booted up my laptop to a blank screen. By "blank" I mean that the laptop lcd was not on at all. I was able to get the laptop to display on my TV via hdmi. I looked at the device manager and the laptop lcd that is usually listed as "generic pnp monitor" was not there. When I went into the display settings, the laptop would only detect the TV screen. I then uninstalled the driver for the on-board graphics chip because I (wrongly?) thought the driver would reinstall on a reboot. Right when I uninstalled the driver the signal to the TV dropped and the laptop would not display on any other external monitors (even after a reboot). I took my laptop in to a repair shop. They could not get the laptop to display on an external monitor, and told me they could not fix it.
What bothers me is that I know the computer is working other than not being able to display anything. I know this because when I returned from the shop I turned on my computer, logged in with my password, and plugged in a drive I use for automatic backup of certain folders. When I checked the drive on another computer, sure enough the folders were up-to-date with files that had not been backed up previously.
I would love to hear any suggestions on how to proceed, bearing in mind I cannot display anything from the laptop.
Thank you.
