I've owned a Microsoft (yes, from Redmond) Wireless Desktop Elite (mouse and keyboard) since 2005 and it has served me well since.
However, I faced a few problems two weeks ago regarding the keyboard.
1. Inability to hold down a key
I don't know how to phrase this. For example, when I hold down "w" in a text field, only "www" or "wwwww" (of any random arbitrary length) appears. Ideally the "w"s should continue for as long as I hold them, but sadly it didn't happen.
It applies to all keys, including Backspace and other keys. It's frustrating.
Otherwise, all keys work normally with a single tap.
2. Erratic behaviour; "phantom key"
I dual-boot Windows XP and Ubuntu, and I configure GRUB to load at start up to let me choose my OS.
Usually there will be a time-out of 10 seconds (then the default OS will be booted) and by default, pressing any key causes the timeout to cancel.
Now the timeout cancels by itself (I saw a flicker of the timeout). It's conclusive that a key was pressed, but I pressed no key!
When typing in text fields, sometimes the cursor shifts back on its own as if the Left key was being held down. I have to type at godspeed to go around this issue.
Occasionally I will hear beeps from the computer itself (not speakers) when I type. Does anybody know what does it mean? (it's the beep you hear when you type wrong stuff in Ubuntu)
4. Fixes I Tried
Normal behaviour occurs occasionally, but right now I'm typing, I'm struggling.
Since my keyboard is wireless, I have tried reconnecting the wireless base and the keyboard many times but to no avail.
I also tried Windows. Behaviour is the same.
Any help will be truly appreciated.
