● Hard disk test—This test analyzes the physical condition of the hard drive, and then checks all data in
every sector of the hard drive. If the test detects a damaged sector, it attempts to move the data to a
good sector.
●
Memory test—This test analyzes the physical condition of the memory modules. If it reports an error,
replace the memory modules immediately.

the battery fails the test, contact support to report the issue and purchase a replacement battery.
