Testing Hardware using ePSA
The ePSA starts running the Quick Test automatically on all detected hardware without waiting for your input. (Except for the LCD test which will look for your response to an onscreen question.) To select a specific part to test, you can press the ESC key to abort the Quick Test and select the Thorough Test Mode instead.

Where to get the diagnostic LED indicators and what they mean for you
On this particular system, the diagnostic indicator is a single LED on the Power Button and it uses both the colour and number of pulses of light to communicate fault codes.
This means the LED indicator consists of 2 groups of numbers for each colour.
- The first number corresponds to the number of Amber blinks from the LED. (from 1 to 9 blinks)
- The second number corresponds to the number of White blinks from the LED. (from 1 to 9 blinks)
| LED Code | Fault Description | Suggested Steps |
|---|---|---|
| 2, 1 | CPU |
|
| 2, 2 | Systemboard : BIOS ROM Failure |
|
| 2, 3 | No Memory |
|
| 2, 4 | Memory Failure |
|
| 2, 6 | Systemboard : Chipset |
|
| 2, 7 | LCD |
