I have a toshiba and recently my computer screens turns completely off when it goes to the login screen but i can still here the sounds and everything the screens just turns off but the laptop is still on, but the weirdest thing is when i shut it down by holding down the shutdown button,the laptop starts again and ask to go to safe mode(like any other laptop or computer does when you shut it down like that)so i go into safe mode AND THE SCREEN WORKS FINE, so i shut it down properly and YET AGAIN THE SCREEN turns off when it goes to the login menu? i dont think i have heard this happen to other ppl, i know their screen goes pitch black or the laptop shuts down but this one is just odd? PLease if anyone has any suggestions please i will try anything!

Because the screen is fine in Safe Mode but turns off as Windows reaches the normal login, this is almost certainly a software/driver problem (graphics driver, a logon UI or a startup service), not a broken backlight or inverter. Safe Mode loads a minimal set of drivers; normal mode loads the full GPU/display stack, so a bad display driver or a startup process often causes the exact symptom you describe. (support.microsoft.com)

Quick, non‑destructive checks to try first: press Windows+Ctrl+Shift+B to force Windows to reinitialize the video subsystem (this often brings a black screen back without a reboot). Disconnect any docks/peripherals and try an external monitor or the laptop’s display toggle (Fn+display key / Windows+P) to see whether the machine is outputting video elsewhere. These steps rule out simple output-mode or driver hiccups before deeper changes. (dell.com)

If that doesn’t help, boot Safe Mode (you already can) and repair the display stack there: create a restore point, open Device Manager and try Roll Back Display Driver or uninstall the display adapter and then reinstall the correct driver downloaded from Toshiba or the GPU vendor. For stubborn driver leftovers use Display Driver Uninstaller (DDU) from its author and run it in Safe Mode (follow DDU’s Safe Mode guidance and back up first). Also perform a clean boot (disable non‑Microsoft services/startups) to test for a conflicting startup item. (wagnardsoft.com)

If the problem persists, check Event Viewer for errors at the time of the failed boot, then run DISM /Online /Cleanup‑Image /RestoreHealth followed by sfc /scannow to repair system files. If corruption or a bad update is suspected, try System Restore (if available) or a Windows repair‑in‑place after backing up data. As others suggested here, uninstall recent software in Safe Mode and use System Restore before a reinstall — these are sensible steps, but follow the diagnostic path above first so you don’t wipe working data needlessly. (support.microsoft.com)

Note: , start with the quick driver reset and external‑output test; then use Safe Mode to remove drivers/startup items. Advice already suggested by , and fits into this ordered approach (quick checks → driver cleanup → clean boot → system repair).

Just to rule this one out: Have you turned the brightness up?

this caused by a polluted software.to resolve this, first login through the safemode and uninstall the recently installed software which you think that may polluted.now shutdown your laptop and try to log in directly.

If it is able to log in using safe mode then try restoring the computer to an early time where it worked well. You can do this by directly going to start menu- Accessories-system tools and system restore depending on the operating system and try to restore the computer to an early time when it was working.If this doesn't work I would recommend that you try to repair the operating system. Im quite sure some files are missing out. Thanks

Since you have a laptop you can try to take out the battery for a few minutes.
Also consider is there might be a virus?
And then if all else fails, when you switch it on look for the 'enter system recovery' option and enter it. You can search there for something that helps, if you can't find anything you can rather
1. Wipe your computer (if you have a back-up ofcourse)
2. Go give your laptop in to for pepairment
