Hello,

I have an Acer Aspire 4730z laptop that has just started having a problem. Both alt keys no longer work! I have cleaned the keyboard, removed it and plugged it back in, rebooted, uninstalled, reinstalled, then updated the drivers, and still nothing.
I have not dropped the laptop, or spilled anything on it.

ANY help would be greatly appreciated. Thank you!

I am hoping this link below works for you it is a PDF version of your Acer Aspire 4730z service manual.

http://tim.id.au/laptops/acer/aspire%20473...30zg%204330.pdf


I had to enter a 4 digit code to make this link work, if this page fails to load for you, use this link below and click the DOWNLOAD link between the two Blue boarders in the middle of your screen and enter the code if it is displayed, . Please ignore the two green boxes saying download acer drivers.

http://www.devicemanuals.com/downloadguide.php

One of these two links will give you the PDF version of your service repair manual.

You can save this to your desk top, just click the little floppy disk in the adobe reader browser.

If you have any problems please ask.

Bruce.

The service manual is a downloadable PDF version of your computer's trouble shooting procedures and shows exploded views of your laptop's inner workings, this is what service techs use for performing repairs on hardware such as keyboards and their keys, it also includes schematics of the circuitry that links the keyboard keys to the keyboard controllor board.
It also has a pictured whole disassembly procedure for your laptop piece by piece in chapter 3 and a trouble shooting section in chapter 4.
This manual is 198 pages long.
This manual will also help you locate the fault in your ALT keys.

Bruce.

Have you tried with an external keyboard, or using the virtual keyboard that is built into windows?

It takes a little bit for the usb drivers for that keyboard to be installed, give it a few minutes then maybe restart your computer afterwards and see if it works then

Did you manage to ever get that working?

I have the exact same problem, suddenly started happening after a year of working fine. none of the ALT buttons work on my notebooks and it's not software related nor does it seem to be hardware related

I indeed fixed the problem. What was the problem? Bad keyboard. I had to buy a new one and now they work fine.
