Vietnamese-language PDF in a 188 KB RAR whose title translates to clock generator circuit. It is a training document on how a laptop motherboard produces its system clocks, not a schematic for one specific model. Guides like this explain the clock generator chip, crystal, supply and enable signals, and which outputs feed the CPU, chipset and peripherals. Use it to understand what to measure when a board powers on but does not start, then confirm details against the schematic for your exact board.
