System Tune-Up runs longer and more comprehensive tests on memory modules, hard drive SMART attributes, the hard drive surface, the battery (and battery calibration), video memory, and the WLAN module status. ● 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. ● Battery test-This test analyzes the condition of the battery and calibrates the battery if necessary. If the battery fails the test, contact support to report the issue and purchase a replacement battery. Using Advanced System Diagnostics 91
