Mouse and keyboard lag in M15x!

Having exhausted any and all options to try and stop a very irritating and increasingly persistant problem here I am to ask the good people of this forum to help me solve my keyboard and mouse lag problem.

I have checked mouse and keyboard options, performance options, startup programs and services, system resources and nothing is amiss. I have done a system restore taking me to before I installed new wi-fi drivers and GPU drivers which was roughly when the problem started to no avail. I have run checkdisks from startup and ran a virus check as well as cccleaner.

The problem is both the internal mouse and keyboard lag. The wireless mouse doesn't lag at all ever. Usually this problem is apparent from startup but sometimes it won't start until sometime later often when a video or animation of some kind is played on the net. Either as part of the webpage or myself watching a video. After that point the lag starts if it hasn't already.

Before I do a complete fresh windows 7 install has anybody had this problem and can help me. The machine is in my sig and is practically a maxed out M15x.

Cheers!!

 

What kind of temps are you running in your rig? Have you optimized your resources in Windows (and cleaned up the registry) from your many upgrades? Doing a clean install may not be such a bad idea.

 

Yes I have cleaned the registry. I did a clean install not long ago. So I hope to avoid doing a clean install. My temps are not bad I keep my machine very clean and very well elevated (9 cell + feet = 5cm breathing space for the fan intakes) Neither GPU nor CPU therefore run hot even though it is really hot here in Japan. As I speak the 920xm is running at 48C across all cores in 26C ambient.

I am sure a clean install would fix this problem however I kinda want to identify what is causing it at least so as to avoid it in the future. Otherwise perhaps clean install or not it will happen again.

 

i can remember having touch pad lag in the past but i believe in unistall and reinstall of the drivers solved the problem. never really had a keyboard lag problem or heard of one....... hopefully it nothing serious

 

I ran the machine yesterday night all evening for slideshow purposes on my projector and even when I finished and unplugged it and used it on battery there was no lag!

Additional today I used the machine twice each time powering it down without lag. Now I type on my third use but this time plugged in and still as of yet no lag. I really hope this issue is gone!

Interestingly I booted last night at 1024x768 reso to fit projector and ran without wireless mouse. Also today I haven't used wireless mouse. Perhaps the wireless mouse is interfering at a driver level and causing lag on the internal devices...?

I will continue using it for variety of things including video without external mouse and if no problem happens will test with the external mouse. If problem comes back then I guess I need to do something with the external mouse......

 

I think I have identified the problem FINALLY!

The probable (I say this as it is still early days lol) is the 9 cell battery going bad. Although it still has decent charge it seems it is the reason both the ps/2 keyboard and mouse lag. Its removal immediately has stopped the problem.

If anyone has this infuriating problem in the future change your battery! Back on my trusty 6 cell now.
