Hi,

Welcome to Fixya. It seems that there is a loose part on the connector of the motherboard to the lcd of your laptop or the connector is bad and it is not normal and not recommended to put a pressure on it because it might damage other IC or parts on the laptop. If you can check the warranty of the computer so that you can send it or bring it to a service center and fix it free of charge. If not then you can bring it to a local tech to heck what seems to be the problem and the part that is need to be replaced.

If you have questions please let me know. Thanks for using Fixya

Cursor Jumping Around


****a piece of Scotch tape over a mouse's laser, might make it work perfectly******
***some optical mouse's need a mouse pad and some work
on any surface.***
i use a lot of computers that have mouse's that i have to
list it slightly and let them ride on a finger when they are
off the mouse pad.
a few weeks ago, my good mouse finally frayed its cord and i
had to start using one of my redundant mouse's that needs a
mouse pad.
i noticed immediately that it could work almost normally if
i lifted it 1/4 inch off the table.
I'm not going to deal with this like that though..
i speculated that it must be because the laser sensor is too
sensitive..( since it works better from farther away....)
i wanted to try to put a piece of scotch tape over it to
act as a diffuser to make it less sensitive, but i was too
busy. lol. so like a month later . i finally tried the tape
idea, and it works perfectly!!!. dam
if you get an optical mouse that goes crazy without a mouse
pad, you should try this

Mouse is frozen, i want to reset my notebook and dont know how


Make sure you haven't disabled the Track pad. Check to see if there is any buttons around the Track pad or around the 'F' keys.
If its not that the computer will have more than likely frozen. Just press and hold the Power Button until the screen goes blank. Then turn back on

My Dynex wired mouse, when plugged in, works but the red "laser" light on the bottom blinks like a really fast strobe light..making my mouse pointer jump around on the screen instead of moving...


My laser mouse flashes too and it works just fine. I'm not certain, yours may be different than mine and maybe it's not supposed to flash on and off, but try cleaning the bottom where the light shines out using a damp soft cloth. Also try using a mouse pad with it... sometimes it may help.
If not, your mouse may be defective. Try exchanging it at the store where you bought it from.

Hi,

Its not compatible. It has different screw listings then V4000.
If you could provide me the product No. which is at the bottom sticker of the notebook of your Compaq v4000 laptop then I can find the part no. for LCD screen which is less costlier and exchangeable.

When my laptop is on a desk or other flat service the cursor jumps around. when its in my lap it works fine. who do i fix it?


Try using a Q tip and rubbing around the mouse pad. It sounds like a crumb may be caught in the corners of the pad which sends false signals to the mouse pad

Touch pad working fine but left clicker doesnt


Usually the green means that the button is pressed. Check the touch-pad buttons for dust or dirt. If they're clean, then probably need to be repaired.

Unresponsive keyboard + mouse pad


I guess you have a mechanical problem, sounds like the mother board have some issues on starting all devices.

If you could use keyboard to go in the bios, and see the screen, if would be the OS that need to be repaired.
