Question about Computers & Internet

1 Answer

I was using an external monitor (emachine E19T6W HD ready monitor) as the primary screen with my Compaq Presario V6000 laptop. I think the cable must have disconnected but because the external monitor was the primary screen, the laptop didn't have a picture from which to control the software program or to return the display setting back to the laptop. Now the laptop shows the Windows XP logo when I turn it on but it doesn't go forward from there. I've ascertained that it's not a hardware problem and I am able to get to the BIOS screen.

Press the FN key and the Key with a small monitor on it. Usually F6 or F7 on most laptop keyboards. You might need to do it once or twice until the screen flickers and comes back.

Please Rate. Thank you.

How to overcome white screen of death

Blue screen of death. (BSD)
Windows operating problem.

White screen means you do not have a video signal.
Problem is;

A) Graphics Chipset
B) Video Cable
C) LCD screen

1) Graphics Chipset:

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

The graphics chipset, or graphics I.C., is properly called the G.P.U.
Graphics Processing Unit.
The GPU, just like a Processor, is mounted to a small printed circuit board, which is the interface used to connect the GPU, to the motherboard.

[ Top View.
The black rectangle with Nvidia NF-06150-N-A2, is the GPU. The greenish square around it, is the Printed Circuit Board. PCB. The little white rectangles with the silver looking band, in the middle of them, are ceramic capacitors ]

The above is the GPU for the HP Compaq Presario V6000 series, of Notebook PC's.

The Compaq Presario V6000 series of Notebook PC's, has a graphics chipset overheating problem.
Also affects the HP Pavilion v2000, Pavilion v6000, and Pavilion v9000, series of Notebook PC's.

The cooling components for the v6000 series, is a Cooling Tube, Heatsink, and Fan Assembly.

Top view;

Fan Assembly (Black) to the right. Fan inside a 'D-shape' shroud.
At the top is the black rectangular finned -> Heatsink.

The slightly flattened copper tube is the -> Cooling Tube. It is sealed on both ends, and filled with Nitrogen.

The first little aluminum looking tab, away from the Fan Assembly, and on the Cooling Tube, sits on the GPU.
It is TOO small in surface area. The reason the GPU overheats.

The next small metal plate that is X-shaped, with four mounting screws, sits on the Processor.

Bottom view;

Put your mouse in the middle of the photo, then move around to enlarge.

Fan Assembly (Black) to the right, come to the top left corner of it.
To the left of the top corner, and mounted to the Cooling Tube, is a copper rectangular plate.
This small rectangular copper metal plate, sits on the top of the GPU.

Coming further to the left of that small copper plate, is the one that sits on the top of the Processor. Has an X shape with 4 screws in it, on the outside.
Inside the black rectangle is the small copper plate, which sits on the Processor
There is some grayish Thermal Paste that has been leftover.

Heat is absorbed by the two small metal plates, sitting on the Processor, and GPU.
The heat is then absorbed by the Cooling Tube.

The Cooling Tube transfers the heat to the Heatsink. The Heatsink absorbs the heat in the middle of it, and radiates the heat away from it by the tall, thin fins.

The Fan Assembly helps carry heat away from the Heatsink's fins.

With constant repeated overheating, the mounting for the graphics chipset to the motherboard, develops a bad contact. bad contact of graphics chipset to motherboard.

The graphics chipset is mounted to the motherboard, with a BGA surface mount. Ball Grid Array.
To explain the BGA surface mount compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket.

The bottom of the Processor has contact pins. 478 of 'em.
The processor socket has matching socket holes,

With a BGA surface mount there are no contact ->pins, nor socket holes.
In place of the contact pins are Solder Balls.
In place of the socket holes are Copper Pads.
(Gold plated also)

The graphics chipset is set onto the motherboard, with the Solder Balls lining up on the Copper Pads.

Heat is then applied at a specific temperature, and length of time.
This solders the graphics chipset to the Copper Pads.
Which in turn solders the graphics chipset to the motherboard.

Constant repeated overheating causes the solder joints, (solder connections), to partially melt.
Then when the laptop is turned off the solder joints re-harden.
This causes Cold solder joints, and makes a bad contact of graphics chipset to motherboard.

1) Laptop OFF, monitor OFF, connect a VGA monitor to the laptop.
Connect to the VGA port on the left rear.
You can use a CRT type of monitor, (Looks like small TV), or a flat LCD screen monitor if it has a VGA cable.

Example of a VGA cable, and VGA connector, (VGA port on laptop),

2) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on. By factory default the display should be on the external VGA monitor.
If Not;

there are at least 3 display options;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press the Fn key down, and hold it down. Tap once on the F4 key.
The F4 key is the Display Toggle-Over key.

No display on external VGA monitor?
Hold the Fn key down again, and tap once more on the F4 key.

Still no?
You have problems with the mounting of your graphics chipset, to the motherboard.

If it is that you Do have a display on the motherboard, then the problem is the video cable, or screen Inverter, or LCD screen.
Post in a Comment if you get a display on the external VGA monitor, and we will go from there.

This is one tech's method to fix the problem. Not repair, FIX.

When i conect my presario cq62 to an external monitor HD i can't see anything please!

You have to hold the Fn key and then press F4. There should be 3 settings. Setting 1. Computer Monitor. Setting 2. Computer Monitor and External screen and setting 3. External Screen only. The order changes sometimes but pretty much all laptops follow this sequence in some way.

Pink Screen on a Compaq Presario V6000

Ok, to resolve this you will need to troubleshoot a little further.
Get hold of an external monitor and plug it up to the laptop, switch screens with the keyboard if you have to, if the colour is still the same then i'm afraid its the video card thats faulty and you will have to have it looked at

Good luck
