for one minute, but then it again.ĭo you know what the problem can be? I don't want to spend money buying something that is not the exact hardware issue. I power off the computer for a while, and boot it again. But the problems with inspirons are very different one from each other. I made some sort of extensive research on the internet. I plugged off every external device connected but it didn't helped at all. I tried to access to BIOS, I could, but then in the BIOS it happened after several seconds. I change to Windows, but the same happened. The screen never set to black, but it was blinking between colors not in the whole screen, I mean, some lines were green, others were pink, yellow, red, and so on. I reboot, and this time the problem was worse. Thinking it was a driver issue, changed the refresh rate, but it didn't work out. I was using Mint, but then, my internal laptop display started to blink between black screen, and then normal, and this repeated again and again and again. I was using my laptop as usual, I have a external monitor plugged into the laptop.Įverything was just fine, I use a dual boot, Windows 10 and Linux Mint 21. Try the Search+ Shift+ T shortcut again to see if it works.Hello there, i have been experimenting issues with my display since yesterday. If your Chromebook does not respond to the Search+ Shift+ T shortcut, open the Chrome browser, type chrome://flags/#ash-debug-shortcuts in the address bar, and enable the debugging keyboard shortcuts option. Press Search+ Shift+ T to toggle the touch screen and try to enable it. Most Chromebooks have a keyboard shortcut to toggle touch screen functionality. Check the box for the Use your finger as an input device option.In the Pen and Touch properties window, click the Touch tab.Once the Control Panel is open, click the Pen and Touch option.Run Windows Update, or download and install the latest drivers for the touch screen, to see if that fixes the problem. You can also check the manufacturer's website to see if there are updated drivers for the touch screen.
If it still is not working, it could be defective and needs to be repaired. Also, wash your hands to remove any oils, and dry them thoroughly, then try using the touch screen again. If the touch screen is not working, try cleaning the screen to remove any dirt, dust, and fingerprints.
