Using Advanced System Diagnostics
Advanced System Diagnostics allows you to run diagnostic tests to determine if the computer hardware
is functioning properly. The following diagnostic tests are available in Advanced System Diagnostics:
●
Start-up test—This test analyzes the main computer components that are required to start
the computer.
●
Run-in test—This test repeats the start-up test and checks for intermittent problems that the start-up
test does not detect.
●
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.
●
System Tune-Up—This group of additional tests checks your computer to make sure that the main
components are functioning correctly. 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.
You can view system information and error logs in the Advanced System Diagnostics window.
