I've got a Dell Inspiron P30E001 Touchscreen laptop. Having an issue where after a short while the laptop will register as though a finger is touching the top of the screen. This doesn't go away and you are then unable to use the trackpad at all as there is no mouse.
The machine has already been completely reloaded but that has had no positive effect.
Interestingly, when disabling the touchscreen through device manager, the issue stops. The issue only returns after re-enabling the touchscreen driver.
Typically, the machine is 2 months out of warranty.
Also, clean the screen as well as you can. There might be something stuck on it that you can't see (that would explain it getting better when you swiped across it).
Have you checked to see if there is an updated driver available for the laptop model? If you use the touchscreen somewhere else on the screen does it "free up" the mouse? Do you allow the laptop to "sleep" when lid is closed? - Ive seen this cause some really weird and dumb issues.
I hear you on the warranty issue... But it could be physically an issue and not necessarily software based. How long does it take from a fresh restart to thinking the screen is being touched?
How annoying! You could try Dell with a warranty request since it is unlikely that the defect was not there a bit earlier within the warranty period. You never know your luck, they may offer some kind of deal.
In all likelihood it is a hardware fault and if you are very lucky a removal of the screen and some wiping will improve the situation. Don't get your hopes to high.
Best of luck
Thanks for the reply,
I've had a look on Dells site for anything relating to the touchscreen driver but I'm not having any joy.
If you touch the screen somewhere else it still detects that you are touching else where and will respond to presses. However, the initial press at the top part is still there.
I believe the laptop is often put to sleep rather than being fully shutdown. It's usually about 5 minutes or so before the screen thinks it's being pressed.
strangely enough after swiping a finger along where it was being pressed. It is no longer seeing it as being pressed down. I'm not sure how ong that will be the case for though.
Have you updated the Touch Screen Drivers and BIOS firmware?
When i worked on behalf of dell i did get a few callouts for this exact issue. Usually Dell would just send me a replacement screen which fixed the issue. and sometimes it was just the drivers or the cable that connects the screen. Sometimes where the pins connects it becomes loose and doesn't register properly.
