FAULTY HP LAPTOPS

El Gato

Hi everyone.

I am posting regarding the motherboard issue with a number of faulty HP laptops sold in 2007/2008.

There is a terminal issue with a number of HP Pavilion notebooks that cause failure of the machine.

I am about to launch a campaign to get satisfaction from HP for people who have defective machines.

You can find out if your machine is affected by logging onto :

http://www.nvidiadefect.com

These will explain the symptoms, the problem causing the symptoms & allow you to register your laptop.

Please, please, please PM me if you or someone you know has a €1200/€1300 HP paperweight at home gathering dust as a result of HP trying to screw us, the consumer.:mad:

Reballing a solder is not a job I would like to do myself & I have been in computing (both hardware & software) for many years.

While professional reball requires infrared BGA oven equipment, many people have also done it with a heatgun, stencil and solder balls.
You can get leaded solder balls which are much better, about .6mm, original electronics are all lead free now but its very bad and weak for hot parts like GPU.

Its not an easy thing at all but if you have no other options its worth trying.

Also there is the very common reflow method AKA "baking" Although this is much more effective and easy with a heatgun. Dont hold it too close to the motherboard, and use aluminum foil to protect everything but the GPU chip.

Reflow as it does not replace the solder is not considered to be permanent fix, but usually works for some time and people have success of 3 or 4 months. Reball, although it works very well, is not really permanent either - it wasn't just the solder that failed, but something called the 'underfill' of the chip which cannot be replaced.
