What is the graphic problem?

Graphics chip repair may be required when a laptop boots up but gives no output either on its own screen or when connected to an external monitor. The sort of graphics chip repair needed will depend on the type of the graphics chip, the cause of the problem and the connection type.

GPUs for laptops commonly have a non-standard slot due to size and weight constraints and may only accept new graphics cards identical to the original one. 

In the majority of laptops the graphics chip is soldered to the motherboard. Over time, especially if the graphics chip is overheating, this connection can become loose. The graphics chip gradually separates from the motherboard, causing all kind of video problems including frequent freezing, overheating or a fuzzy or blank display.

Types of graphics chips

Royal Computer team can carry out ATI, Nvidia and on-board Intel graphics chip repair on almost any make and model of laptops from our premises in Central London. The most powerful graphics processor units (GPUs) typically interface with the motherboard by means of an expansion slot such as PCI Express (PCIe) or Accelerated Graphics Port (AGP) and usually involves a straightforward replacement.

The repair process

The graphics chip repair process used in this case is a Re-flow to solder the chip back onto the motherboard. If the graphics chip itself is faulty, it needs to be removed and replaced by a new chip.

The graphics chip replacement is usually done by using a special machine called BGA rework station. this machine uses infra-red heating to melt down the solders on the graphics chip pins. The machine has a pump to take out the chip.

This type of graphics chip repair involves re-balling technique to resolder the new chip onto the motherboard.
