Acer Aspire 1420p (PDC version)

Question

I installed the developer preview on this laptop the other night and there is one driver that will not work properly: ST Micro ScreenDetection Driver. I noticed this laptop was on the list of hardware used in the MS labs and was wondering there was an update driver available for Windows 8?

Thanks.

Answer 1

Is this a driver that you obtained from Acer? What is the driver version number you have currently?

Answer 2

Yeah. There are two drivers on the Acer website and I have tried both. Windows blocks both of them from starting.

Versions: 1.00.00.16 and 1.0.0.1

Answer 3

What message do you receive when you install the driver?

Answer 4

They both install just fine, but when Windows boots, there is a MessageBox that says "Fail" or something like that and if you look at the device in the Device Manager, it has an exclamation point.

Looking at the device properties, it says something to the effect of, "This driver was prevented from loading due to a known problem with Windows".

That may not be exactly what it says, but I am going from memory, as I don't have the laptop with me this morning.

Answer 5

I have the same laptop form the PDC 2009 and the same "issue". The driver that you mention and that fails running is for the G Sensor. That's probably why the screen does not change orientation automatically (as it does on Win 7)...

I must say that the overall touch experience of the Preview with this hardware is quite good!

Answer 6

I agree. The overall experience is pretty good, except that it seems to switch from "touch-only" mode to desktop touch mode at random, which is a little annoying when I want to use it just as a tablet.

As for the driver, I figured since MS uses this hardware in their lab, they might have an updated driver for the G sensor. Any way you can find that out, Paul?

Thanks.

Answer 7

Sounds like this is a driver issue.  When you get back to your laptop, please verify the driver information currently installed on your computer and we will make sure the information is passed on to the right feature group for review.

Answer 8

Like Jason mentioned we both tried the two versions of the driver available from Acer.

ST Micro ScreenDetection Sensor Driver 1.00.00.16 and 1.0.0.1. (Both actually showed as 1.0.0.1 in the driver properties on my machine).

The exact message showing in the Device Status is: "The software for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)"

Thanks

Answer 9

Hey everyone- we do not have a proper Windows sensor driver for this hardware platform. The driver is proprietary and does not work with Windows 8 screen rotation or apps.

If we get updates, I'll post info on the "Tailoring your Metro style app for hardware and devices" forum.

Thanks,
Gavin

Answer 10

Just to follow up. I did eventually get the driver to load, but it still doesn't work. All I get now is a warning about some programs not supporting portrait mode, but nothing else happens.

Answer 11

Bump!

Still no solution?

MS can't made a generic driver for us?
