Laptop touchscreen only works when the screen is almost shut

goverbeek16 · Sep 6, 2018

I own a Toshiba Satellite S55T. I have tried updating and uninstalling drivers with no luck. The drivers only show up under "hidden devices" when the touchscreen is "disconnected."

My touchscreen works only when the screen is almost closed. It's as if there is glitch in the code. Instead of turning the touch screen off when the screen is closed, it turns it on.

Then it sounds like a hardware issue, not a software one. I would suggest having it looked at by a tech.

It seems to predictable for hardware problem. The only thing that would make sense is if something was plugged in every time I shut the screen, but that does not seem likely.

It seems to me that laptop screens are supposed to turn off when you shut the lid so things are not pressed by accident. Somehow this got reversed.

I'd take it to get it fixed, but I'd spend more than the laptop is worth.

Seems like a sensor issue.

Sounds like a mouse cable that doesn't work unless held a certain way--that's broken wires that touch again whenever the cable is bent just right. The screen has a cable that twists every time the lid is moved. It does not last forever.

Search for your model laptop + "LCD cable" to see if the digitizer uses a different cable They can be surprisingly cheap and such a common problem that you can usually find a how-to video for how to replace it.

This may be a little late to be of any help to goverbeek16, but maybe someone else might find it useful;

A client brought in a Satellite S55T-B5335 for the exact same issue. After isolating the symptom I discovered that the Touch Controller Cable had a break in two of it's seven, very fine wires, right were the cable passes through the hinge. It seems the repetitious opening and closing of the lid had, over time, worked the hair-thin wires to the breaking point. The broken ends would contact just enough to allow the digitizer to function when the lid was around 4" from closing. The hardest part has been locating a NEW replacement cable and, as of this post, still no luck.
