The PC system has to cool down before it can be reactivated.
Information on Hard Drive / Memory Capacity
Information on Hard Drive (HDD, SSD, eMMC) Capacity
The hard drive capacity shown by Windows is lower than that stated by the hard drive manufacturer
due to a difference in calculation.
ENGLISH

6Introduction / Important Safety Precautions
Manufacturer Hard drive manufacturers use a decimal definition of 1 KB = 1,000 Bytes.
100 GB Storage Device (HDD, SSD, eMMC): 100,000 MB / 1,000 Bytes = 100
GB
Windows Windows use the binary definition of 1 KB = 1,024 Bytes.
100 GB Storage Device (HDD, SSD, eMMC): 100,000 MB / 1,024 Bytes =
97.6 GB
RAM Capacity
RAM capacity shown by Windows may be lower than the actual capacity because the PC uses shared
memory for BIOS and the integrated graphics card.
Due to BIOS using shared memory, 1,024 MB RAM may be reported as 1,022 MB or slightly less.
If the PC has integrated graphics card, 1,024 MB RAM may be reported as 1,022 MB or less than
1,000 MB.
