Customer :

Compac

Michael Johanson :

Thanks, XXXXX XXXXX an LCD or a CRT?

Customer :

laptop

Michael Johanson :

Oh, was wondering.

Michael Johanson :

Give me just a few minutes to look a few things up. This is generally caused by a bad connection to motherboard in laptops or a bad ground.

Customer :

not sure

Michael Johanson :

No, I was just telling you what causes this in laptops :)

Michael Johanson :

But I need a few minutes to look up some data, what model is that?

Customer :

I don't no. Where can I fine that. Sorry

Michael Johanson :

It shoudl actually be between lcd and keyboard or even on bottom.

Michael Johanson :

is that a black or silver model?

Customer :

black

Michael Johanson :

on bottom then.

Michael Johanson :

dont drop it :)

Michael Johanson :

How bad is the scroll?

Michael Johanson :

is it just lines that scroll from top to bottom?

Customer :

Got some numbers for hope i helps service tag cq50139wm p/n fr972ua#aba s/n2ce8341rbp The screen moves realfast I think up. Does it some times them stops.

Michael Johanson :

Ok

Michael Johanson :

Oh, ok, thats the walmart laptop?

Customer :

I don't know it was a gift from daughter. Sorry. Most likely I don't think they could spend alot. Nice gift though..

Michael Johanson :

yeah, they arent to bad.

Michael Johanson :

Ok..

Michael Johanson :

2 things cause this..

Michael Johanson :

First thing I already mentioned, Can be the connection from LCD to motherboard is a bit loose

Michael Johanson :

Does it ever feel hot to you? I ask that because Second reason this is caused from is heat.

Michael Johanson :

grr, typos bad, sorry

Michael Johanson :

Figure, every time you open and close laptop lid, there may be a sligt tug happeing to the connection to board where it plugs into under teh keyboard

Customer :

How do I check the bad connection. Some I do have it setting on the table on a place mat. But it does that on my lap also.

Michael Johanson :

yeah, big issue is making sure that it can can suck in air from bottom and blow out on side

Michael Johanson :

The fan running on it ok?

Customer :

yes

Michael Johanson :

you can also use some canned air and blow it through bottom fan holes and make sure any dust build up gets pushed out. it can actually build up inside like link from a dryer.

Michael Johanson :

Im trying to find some instructions to show you how to check the connection.

Michael Johanson :

Its easier said then done.

Michael Johanson :

Heres a video showing how to deal with high temps. http://www.youtube.com/watch?v=8X6Im9L8fmw

Customer :

I will try the air. It does seem to do it if I move the lid.

Michael Johanson :

Ok, Its teh connection then.

Michael Johanson :

Thats what I figured.

Michael Johanson :

Just a sec,

Michael Johanson :

This may help :) In fact it will.

Michael Johanson :

Service manual for your laptop.

Michael Johanson :

Let me find right page youll need.

Michael Johanson :

Ok, look at page 15 on that shows teh exploded view

Michael Johanson :

Essentailly. where your power button lays at, that strip comes off. and then 4 screws hold Keyboard in place

Michael Johanson :

remove those and you will then have access to the plug from lcd to board

Michael Johanson :

that just pulls out, I woudl pull it, blwo it off, and then firmley reseat it.

Michael Johanson :

wow, my typos are bad today, im sorry about that

Michael Johanson :

now.. the area that pulls off between keyboard and lcd. there may be a slight chance its held in place by 2 screws on bottom. But thats easy enough to figure out. O actually do not think its help in place by screws, just use a precision screwdriver and gently pop it off

Michael Johanson :

But..here we go!

Customer :

I guess I should turn the computer off and try this.

Michael Johanson :

Oage 52

Michael Johanson :

Page 52.

Michael Johanson :

Um yeah. dont do while on :P

Michael Johanson :

page 52 shows how to remove Keybaord,

Michael Johanson :

its just under keyboard and you cant miss teh wire running from lcd to board obviously.

Michael Johanson :

52 and 57 are the best pages.

Michael Johanson :

But yeah, reseat that amd I still suggest blowing air through teh fan to break up dust.

Customer :

Whats the amd will try thanks

Customer :

If not have a cisco program at my school will try that.

Michael Johanson :

You bet, please leave good feedback after you click accept. Its very much appreciated :)

Michael Johanson :

I think you can follow those directions, its very well written and consise :) Youll be fine.
