I have an Acer Aspire Z5771, Intel(R) Core(TM) i5-2400S CPU @ 2.50GHz 8GB ram, The wireless keyboard stopped working (not sure if it was after the last windows 7 update). I have replaced the batteries and did not fix the problem. Checked in Device Manager but drivers appeared to be working properly. At present I do not have a spare keyboard to try. Does anyone have any further suggestions that I could try? At present I’m using the ‘virtual keyboard’.
Thanks

You might want to check the manufacturer’s website and see if there are newer Windows 7 drivers for the device. If there are, download and install them and reboot and see if your K/B doesn’t work then.

How charged with punishments the scroll,

I am the captain of my soul.
