This malfunction appears more and more often, and its elimination is very expensive. It can be caused both by problems in the soldering of the south bridge chip and by damage to the flexible cables that come from the touch pad or keyboard. The south bridge may fail due to overheating, short circuit, shock or mechanical pressure on the laptop case. In this case, there is poor contact of the microcircuit with the board. Here, you need the help of a laptop repair professional.
Typically, these symptoms occur when a laptop graphics chip or video memory fails. The repair consists of replacing these chips, which have a complex BGA case with solder balls under the case without leads along the contour of the case and are re-soldered only at special soldering assemble and disassembly stations. If the laptop video card burns out, the laptop may not turn on at all, or it may turn on. But the image will be absent. Generally, laptop video system malfunctions are associated with overheating or mechanical to the motherboard.
