I have a Lenovo y50-70 laptop that won't start. I downloaded an updated for Windows 10 and then reset so the update would be applied but all I'm getting after it boots up is a black screen and I can see the mouse and nothing else. It shows the Lenovo logo and then nothing. Ctrl+alt+delete won't work and neither will any other button combos. I've tried running out the battery and holding the power button for a while but that didn't work either. Is there anything I can do to get my laptop working again?
Laptop only displays a blank screen after Lenovo logo?

You just got to love Windows 10 and its updates. Not a day goes by that I don't see this a dozen or more times.
The worse case scenario is the hard drive has failed completely because of the update. That would not be the first time 10 took one out. The first thing you want to try to do is run a Windows System repair disc to see if it can fix the problem. With any luck it might find a problem it can repair. If you do not have one and can find someone who has the same version of Windows you do then you can use the link below to make one.
For Windows 8 and above systems.

If that does not work, the the next thing is to try to recover your files. For this you will need a bootable thumb drive(flash drive) so you can boot the lappy. This will also allow you to verify that the lappy and its hard drive is good and all you have is a Windows problems. To boot the system you need to make a bootable thumb drive. You will need to find a working puter to download Unetbootin USB installer. You need to read the instruction carefully and know a little about Linux to use this. There can be dragons present if you do not understand what your doing. I make no guarantees.

Once you make the bootable thumb drive you need to add a OS for it to boot. I recommend Linux Mint ISO. Its UI is similar to Windows. Download Cinnamon 32bit.

If you have a Windows 8 or above then you need to turn off secure boot and select boot from USB before using the thumb drive. The thumb drive boot will also allow you to check out the rest of the puter. It helps to have a thumb drive or a external drive hooked up when you boot so you can copy your data and files to.
If it has a CD/DVD you can burn Linux Mint ISO right to a CD and boot with it.
Once you got the bootable thumb drive created, insert it into one of the USB ports. Also plug in the medium you selected to copy your files to. Press the power button and start tapping the ESC key. This should bring up the boot menu. Select the USB thumb drive and it will boot to a menu asking if you want to start Linux Mint. Click on Mint and let the system boot. Find your hard drive and copy your files to your back up medium. If the hard drive is a SATA drive it will show as sda. If it has partitions then the first partition (C Drive) will show as sda1, the next partition will show as sda2 and so on. If you have 2 drives the next drive will show as sdbx. X being the partitions if it has any. Normally external drives show as sdd or sde. I have seen Linux recover data that people claimed could not be recovered. Keep in mind while looking for your files, and this is a Vista or above version of Windows, that you have to find your USER folder. The folder will look something like this. \Users\nameofuser\Documents. Repeat that for music, pictures, and videos.
Lets see if the hard drive can be made to boot again.Since the repair options are not working your best bet is to reset the lappy back to factory settings as if it just came out of the box. This will erase everything on the hard drive.
Make sure you back up all your files before doing this.
If your resetting a lappy, make sure you have the AC adapter plugged up. You do not want this process interrupted. This should take one or two hours. It is best to check on it to make sure everything is going fine.
Windows 8 and above
With the system off press the NOVO button and it should start up and display the NOVO menu screen. Use the arrow down to recovery. Press enter and you should see this screen.

Select recovery and then next.
Windows 10 may not be recognizing your laptop screen as the primary display. This is very common for Windows 10, especially after upgrades. Have you tried using the FN key combo to select displays? Try hitting the space bar when the mouse cursor is on the screen. You will have to do this "in the blind" - type your logon name, hit Tab, type password, then hit Enter.
