Suddenly, my Lenovo T410 started booting into a blank screen. However, the computer seems to be otherwise working quite normally. When the computer is started, BIOS splash screen shows up, Windows starts to boot and shows the animated start-up logo. However, when the system switches resolution and is about to display the login desktop, the display is just blank, although not turned off. Even the mouse cursor isn't shown.
The computer is responding to commands like pressing the power button or the Fn+F10 (?) combination to hibernate. When resuming, the “Resuming Windows” banner is shown, but then again just a blank screen. The last time the system was working correctly I put it on sleep, and it hibernated automatically after a few hours.
I attempted to connect the computer to an external display both via VGA and DisplayPort, both with no result. Even tried Win+P to switch displays. I also attempted to connect to it via network, but I wasn't successful — however, I didn't spend much time with this and it's probable there was some network or authentication issue on our corporate network.
This problem occurs even when booting into safe mode (all three options).
I can't tell if some drivers weren't updated recently. I don't reboot much, rather sleep / hibernate, and don't keep track of updates being installed (although I do keep the computer up-to-date).
- Windows 7 Enterprise Edition (64-bit) with latest drivers and patches.
- Dedicated NVidia graphics card.
- There are no unusual apps or non-system services running besides the MS Essentials antivirus and VMware workstation (7.1 I guess).
Any thoughts what this can be and how to resolve it?
UPDATE: This model has just the single nvidia graphics, no built-in intel graphics.
I managed to boot into the System Recovery Console and restored to the state a few restore points back. However, without any luck. Since the SRC boots with a VGA driver correctly, I assume the problem is in nvidia drivers. Booting with the "low resolution (640x480)" option doesn't help as it apparently uses the nvidia drivers as well.
