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 graphics chip, the cause of the problem and the method of connection to the motherboard.
We can carry out nvidia, ATI and Intel graphics chip repair on almost any make and model of laptop from our workshop in Manchester.
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. GPUs for laptops commonly have a non-standard and often proprietary 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 display problems including freezing, over heating or a total blank display.
The graphics chip repair process used in this case is a Re flow to solder the chip back onto the motherboard. If the graphic chip itself is faulty, it needs to be removed and replaced by a new chip. This type of graphics chip repair involves soldering the new chip onto the motherboard.
