R4000 keyboard problem

This started as a sporadic problem, now is a nightmare. All of the sudden, programs start to pop-up. Always the same (media player, system info, compaq support). If you're in a word processing program (even notepad), characters start to be written by themselves, repeatedly. The work-around have been many, since it has gotten worse. The first one was just press all keys on the keyboard. Then tried an external USB keyboard which worked for some time, then the problem started again. I even physically disconnected the laptop's keyboard & mouse to use only the external usb keyboard/mouse combo. Still the problem shows-up. Any help greatly appreciated

Starts and stops sporadically during cycles

the lengths of the programs should be on the lid...if not somewhere in your manual.
i have an old one & it takes forever.
the starts & stops are normal (i think) cuz mine has always done it.

I have a compaq presario r4000 will not boot up correctly

When you start it up, go to the BIOS option and select "peripheral" settings. I don't know which column its under but you want to turn the network adapter off. If that makes your Operating System come up working (And you may have to come up in SAFE mode the first time), then you can always go back and reset the BIOS to recognize the network adapter, or install a different one.

I have a MX 3200 wireless keyboard and mouse. the

The problem was that ther keyboard was encrypted for my protection. this sometimes prevents the keyboard from connecting to the receiver and therefore the computer. to stop encrypton: press the left CRTL + left ALT + F12 key at the same time. Press the connect button on the receiver (you only have a few seconds to then press the connect button on the keyboard. Press the ESC key. Now you must start the encrypton again. Install SetPoint software from after you save and run the program, then press left CTRL + left ALT + F12 keys. sometimes there is an encrytpion wizard that pops up to help you further encrypt the keyboard, but this does not always pop up. It didn't on mine. My keyboard just started working right after i re-sarted the encryption.

hope this helps others that were in my situation.

There is no driver from Compaq because it just uses a standard driver from the operating system.

Try removing the keyboard from the device manager.

Then restarting the computer.

Let me know what happens.
