And if the matrix could remain intact, it could hurt the motherboard notebook. Microcracks on the system board can not affect the efficiency of the laptop in the normal state, but if you get it it in his hands and push in a certain place, it will break the tracks at the site of microcracks and the laptop freezes or just turns off. Therefore, after inspection and loading the operating system try to slightly bend the basic the notebook, the board back and forth. Generally, load an operating system – the most serious test for the computer. And if the system is booted, the options for the critical failure left the laptop quite a bit. So Thus, if the operating system on a laptop is not set, it is a serious reason to run into a malfunction. After loading, the system can continue to hang or laptop just turns off – it happens in mainly due to overheating of the various circuits of the motherboard, usually the processor.
Sometimes, the flooded water, tea, coffee, laptop overheating occurs on the video chip or other important large chips, which by nature of their activities require refrigeration. To identify such hidden faults in a laptop is very difficult for a few minutes – it is precisely the lottery, which was mentioned above. Of course, you can run some tests for 100% load cpu and wait a few minutes until the start of the processor fan and you can already highly likely to approve of the performance of the mainboard.
