Re:Anyone have touch screen issues with 300e (Chromebook)?

2021-03-03, 0:20 AM

Our 300e's are out of warranty too and our district doesn't have a lot of money. That's why we keep on trying until it works. I posted early that it worked on a Dell 3440.  It wasn't a Dell 3440 it was a Dell 3350. The 300e 1st Gen I mentioned earlier, I troubleshot it off and on for a bout 40 days. The last thing I tried worked. I disconnected the  screen cable from the board (silver rectangle thing) then I reconnected it and restarted the computer.  The touch screen is operating  again. Don't throw in the towel and don't quit. You Can Fixit!! Stay Encouraged!!

We get those issues with Ghost touches all the time.  Sometimes disabling the Touch Screen helps regain use of the machine.

Obviously you will lose the "touch screen" feature. The only real way of fixing this issue is by replacing the LCD/ digitizer assembly.

Hey!   Thanks forthe suggestion. I just tried changinging the screen to try to get the touch screen to work and it didin't. work. The only success that I had is what I posted back in March. I disconnected all the ribbon cables and the screen cable and the battery. Then I reconnected everything. My suggestion doesn't work for all the 300e 1st Gen, but it does work for some of them. Please share if you find another solution.  A lot of school districts budgets have been slashed and they have many computers that they must keep working.

Depending on the generation. I know for my school district, I have had to replace the screen. It tends to happen with the Gen 1s with the pencil touch more often than our Gen 2s. We tend to go through chromebookparts.com to get our screens. The issue is if it is the pencil touch type, the are the more expensive of all the 300e models. We are also at the point of saving screens from other broken ones that have issues with things like Motherboards.

I hope that helps.

I have a Lenovo 300e Chromebook that was ghosting so bad I kept it to run some tests.  There is no software update that will fix it, this a purely a hardware issue.  The solution that Lenovo posted on their site describing how to turn off the touchscreen does not work because the touch comes back if you are in kiosk mode (like TestNav app) or trying to login in.  Unplugging this cable behind the LCD screen is the best fix, it turns off the touch screen permanently.  Unfortunately the Chromebook is no longer touch screen capable, but this is the best fix if they are out of warranty or we cannot afford the LCD screen replacement.  Replacing the LCD screen is the permanent fix.  Like many others, our district purchased a bunch and the warrant is running out.  Purchasing a replacement screen is not a viable option, the fix I mentioned earlier will at least make them usable.
