White Lines

Question

So this morning, my laptop displayed chunks of whites when I turned it on, and didn't go to the startup. But I learned that when I turn it of, by shutting the screen down, I'm a gentle way, then turn it back on, it works and goes to start up, but with few faded whites on the upper and lower part of the screen. Please help me, this is not my laptop and just a borrowed one and I don't have that much money either so the hardest thing I can do now is open this laptop

Answer 1

Boot the laptop into BIOS (press F2 on the laptop manufacturers logo screen when you start the laptop), are those lines also visible on the screen in BIOS?

If the lines are visible on the screen in BIOS, then that is caused by a hardware fault on the screen, it is not a software problem, you will not be able to fix this yourself.

Answer 2

Try the least invasive steps first:

1. Disconnect anything external from the laptop: USB devices, SD cards, external monitors, docks, and other accessories.
2. Make sure it has power. Connect the charger and let it charge for at least 15 minutes.
3. Reset the graphics driver:
   • Press Windows key + Ctrl + Shift + B
   • A beep or brief screen flicker can mean it worked.
4. Force a restart:
   • Press and hold the power button for about 20 seconds.
5. If Windows starts but the screen still shows white/faded areas, check whether the issue looks different in Task Manager:
   • Press Ctrl + Alt + Delete.
   • If needed, press Ctrl + Shift + Esc to open Task Manager.
   • If Task Manager flickers along with the rest of the screen, the display driver is likely involved.
6. If the laptop can boot, try Safe Mode and then update or roll back the graphics driver:
   • Hold the power button for 10 seconds to shut down.
   • Repeat startup interruption 2–3 times until Recovery Mode appears.
   • Go to Troubleshoot > Advanced Options > Startup Settings > Restart.
   • Press F5 for Safe Mode with Networking.
   • Open Device Manager > Display adapters.
   • Right-click the GPU and choose Update driver.
   • If the problem started after a recent update, choose Roll back driver instead.
7. If the screen remains unstable, try System Restore:
   • Boot into Recovery Mode.
   • Go to Troubleshoot > Advanced Options > System Restore.
   • Choose a restore point from before the issue started.

If the laptop still shows white blocks or faded white areas after these steps, that points to a likely hardware display problem. Since opening the laptop is not an option, avoid disassembly and use repair/service support instead.
