To explain a BGA surface mount; The older Intel Pentium 4 processors that used a Socket 478 processor socket, had contact pins on the bottom of the processor.
A chipset using the BGA surface mount does not have contact pins. It has Solder Balls in place of the pins.
There is no socket with socket holes. There are Copper Pads.
The chipset is set into place with the Solder Balls lining up on the Copper Pads. Then a specified temperature, and specified length of time is used to melt the solder balls. This solders the chipset to the Copper Pads, which in turn solders the chipset to the motherboard.
Excess heat, due to the laptop is overheating, can partially re-melt the solder connections made, and cause a poor contact.
May be caused by the laptop is dirty inside, and the cooling capacity of the cooling components, has dropped tremendously.
May be due to a poor cooling system design in regards to the graphics chipset.
The cooling system may be adequate enough to keep the Processor within it's specified temperature operating range, (Thermal Limit), but NOT adequate enough to keep both, Processor AND graphics chipset cool.
Using the HP Pavilion dv9000 series of Notebook PC, this video gives information on the problem in more detail,
To make sure what is really wrong we need to break down couple of things, have you tried connecting a external source such as to a monitor or a tv via s-video or vga. If it is able to display to the external source then there is something wrong with your screen. Now is it completely dead and you cannot see anything or are you able to see something but the display lights are not litting the display. If that is so, then your backlit is dead and you will need to replace the entire screen. In my honest opinion if that is the case I recommend you to by a new laptop, because parts/labor cost would cost more then your medium powered new laptop.
I don't know that it is a common fault with this specific model, but laptops in general have this issue mostly due to a dying LCD power inverter. It is typicaly located at the bottom of the LCD screen and costs between $30 - $75 dollars for the part, and usually $75-$150 for someone to replace. If you like the laptop it is usually worth it to have replaced. You can also hook up a monitor to the VGA port on the laptop and then go into your display control panel and enable 2nd monitor to use it instead of your laptop lcd.
Hi Prince, has your laptop experienced a squeeze or fall recently? I have a few suggestions. Plug another monitor into the VGA or DVI connection on your laptop. See if you are getting the same problem. If everything is working fine on the external monitor you would have eliminated the drivers being the problem. I suggest getting the LCD display changed. If your laptop is under warranty, you can get this done for free. However, if it is not under warranty you may have to replace it either yourself or take it to a local Acer specialist. If you chose to install the new display yourself, there are handy tutorials on removing and installing the screen on the Acer website. I have noticed that many times the Acer TravelMate Notebooks have experienced display issues. I hope you get your problem resolved soon.

Try reseating the RAM modules first. The RAM may be faulty or reseating to make proper electrical connection. Get the RAM tested in another laptop or at your friendly computer shop.
Can you get into the BIOS configuration?
Did you power up the monitor first then the laptop? This method will divert the video information to the external video port first automatically.
If you don't get an image on the monitor and the hard drive doesn't appear to be spinning, then you could have a faulty motherboard.
Your concern is a typical problem with LCD displays/monitors. There could possibly be three (3) reasons why it is behaving as you have posted. 1. Backlight/Inverter problem; 2. LCD panel problem; 3. Video card problem.
You can do initial diagnosis by: a. connect the laptop to an external monitor. Using the Fn + F? keys, activate the external monitor to be the default display. If it works, you have eliminated the possibility of the video card having a problem. If it likewise did not display anything or blanks out after sometime, then you have just confirmed that it is the video card that is a problem.
If you have ruled out the video card (using above procedure), you can proceed determining if it is an LCD panel problem or backlight/inverter problem.
To determine if it is a backlight/inverter problem, run the laptop normally even without a display. Let it boot and run through its startup sequence even if you can not see anything. Using a flashlight, shine a light obliquely to the face of the LCD display. if you can see some semblance of your desktop albeit dark, then you have just confirmed that it is the backlight/inverter. If even with the aid of a flashlight, the display s completely blank, then it is possible that the LCD display panel is defective. In some cases it is the flexible flat cable that is at fault.
With any of the aforementioned possible problems, opening the unit is required. This would need familiarity with electronic components and circuitry, use of a DVM and perhaps even a soldering iron. Should you not be comfortable doing this, it would probably be to your best advantage to seek the services of a qualifiedly professional.
Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.
Welcome to Vista. Windows Vista is automatically set up to power down after you have left it alone for too long. If you press the power button everything should be fine. Otherwise tell me what happens.
