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.
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. (Not advertising for this guy, just for reference of method )
If your laptop won't power on or stay on for long then follow these quick and easy steps to troubleshoot the problem.
Ensure your battery is holding a charge. Some laptops will automatically shut-off if the battery won't hold a charge. In that case, replace your battery with a new one and retry. Check your charging lights or indicators to see if your laptop is getting power and charging.
Check your AC to DC converter (the little black adapter you plug in your AC outlet.) This converts AC power into DC power. Is it abnormally hot? If so, it is probably burned out. You will need to replace it. Note: High heat is not a true indicator of malfunctioning. It can be dead and cold as well. No power indicators on your laptop could be a sign of a dead or bad converter also. Converters WILL get hot (this is normal.) If it is REAL hot (burning hot when you touch it), then this is not good.
Check your power cord. Are there any nicks, cuts or kinks? If so, unplug it from the AC power and repair with electrical tape or better yet, replace it. Many computer salvage stores carry power adapter cords. They're cheap and could save you from electrical shock.
Check your laptop lid switch. If it is broken or not lit, you may have power but your screen may not come on. This is usually a little button located close to the lid hinge that turns on or off your screen when your lid is open or closed respectively. Normally the operator does not push this button. These are fragile and broken easily on some laptop models. Sometimes these can be repaired, more often they will require replacements. If you aren't an expert repair person, get a technician to repair or replace it for you.
If you have tried these easy solutions and it still won't power on, then your problem lies elsewhere. You may have an internal power switch or voltage regulator problem. Internal problems will require professional help so go on down to your local PC store and have a qualified technican take a look.
When you connect it to wireless make sure you go into control panel / network view your connection right click on local area network connection choose disable then connect to your wireless connection. Right click your wireless icon by your clock choose connect to wireless network or view available local wireless connection.
The reason it shows the compaq logo is because that is the motherboard you have installed. HP is just your case if I am reading your question properly. Did you custom build this? Which processor is in it? Probably the wireless card isn't being recognized because of your 64 bit operating system. Windows 7 has a lot of hardware driver problems right now.
usually all drivers for Compaq and HP computer systems (portable and non-portable) can be found on the HP support website (Click here to go to it), simply go there, chose your region, than your country, enter your model number (not the series, the model number, you would usually find it on the service tag, or wherever you would find a serial number), but be sure to chose "Download drivers and software (and firmware)", and than chose your operating system. Hope this has helped.
