Wireless devices, specifically keyboards with batteries, are designed to shut off after so many seconds to conserve battery power. Even TV remote controls are designed with that feature if they are laid down and a button is pressed.
Either select fewer files or go wired.
I've tried several wireless keyboards which working on 2.4ghz frequency -
Trust, HP and MS and i get annoying problem with all 3.
When i'm selecting multiple files in windows explorer with Ctrl and left
mouse click the selection is disappear after holding Ctrl longer than 10-
20 seconds no meter how many files is selected.
I'm not tried keyboards on 27mhz because i need longer range in my working space.
On wired keyboard that is not a problem, only on wireless. Batteries is
new and fully charged and the distance between keyboard and usb receiver
is only one meter or less. I tried all 3 keyboards on other home computer
and the problem persist.
Models are:
HP Wireless Elite Keyboard
Trust DS-4700
MS 713W
Is these keyboards faulty or problem is in 2.4ghz transmision somekind memory problem?
What experience have other users of using wireless keyboards on 2.4ghz?
I'm using windows7 4gb ram.
