I came with a laptop to reinstall Windows, installed a pirated Windows that eventually refused to be updated and worked for a dump, the sound quality deteriorated by 2 or even 3 times, which is why in order to hear something, I had to set the volume to 75% this had not happened before and always watched everything with sound 35, in as a result, I took the laptop to the 5 element service and everything was done properly, a licensed working Windows was installed and the sound became much better
I repaired the phone here 2 times, refilled the cartridge. There were no questions about the quality of the service provided. After the repair, they give a six-month warranty. Pleasant employees.
The laptop processor has been replaced, there are no questions. But the CPU temperatures jumped from 70 to 90 in front of my eyes, the CPU throttled under good load - I had to get to the CO on my own. During disassembly, the following turned out: one bolt on the CPU was not twisted to the end, which was why there was a skew and it was good that it did not reach the chip. The thermo interface itself is not thermal paste, but a thermal paste, abundantly superimposed on the CPU and GPU chips without any need. It's the same story with liquid thermal pads. I don't know what kind of thermal paste and gaskets, I replaced the entire thermal interface with the Arctic mx-4 and fehonda. As a result, the temperatures on the CPU stabilized at 55-65 degrees under load and do not jump like crazy every second, the laptop is cold as the heart of the former. I hope that this is only an isolated case of mine, and not a deliberately done "job".
