The Power button on the Alienware laptops also works as a battery status indicator. If you are seeing asolid amber flash, it means that the laptop is running on battery and has less than 10 percent charge remaining.
Another function of Alienware’s power button is to notify the user of any system or hardware problems. If one of Alienware’s internal components fails, the power button will typically blink in a pattern. This light pattern flashes with a red and blue combination.
For example, if the power button blinks red twice and then blue once, this suggests that the system has detected a processor failure. The light combination is expressed in terms of light code, and the code, in this case, is 2-1.
As per Alienware’s service Manual, these are the different light patterns with their implications:
Note: The diagnostic light codes and problem description may differ depending on the Alienware model. To get the specifics, consult your Alienware user manual.
Now, take note of the pattern of the light code from the power button and match it to the problem description from the table above. Then apply the fixes necessary to solve the issue, as suggested in this article.
Fixing Processor Failure
A power button flash with either a 2-1, or a 2-6 light code hints that there can be some issues with the processor or the system board. The processors can undergo such issues because of thermal throttling, voltage fluctuations, or if the laptop has sustained physical damage.
If the laptop is working normally even after the light code, the issue could be minor. In such a situation, you canpower-drain the laptopand see if this gets rid of the problem.
To do this, turn off the laptop and disconnect the components from it including the AC adapter. In case the laptop has a detachable battery, disconnect the battery cable too. Now,press and hold the power button for about 20 seconds. This will drain the excess static electricity stored in the motherboard.
Once done, put everything back in place and turn on your laptop. Check the power button and see if you still get flashes of a similar pattern as earlier. If the problem persists, contact the Alienware customer center.
Fixing BIOS-Related Failure
A BIOS-related failure in an Alienware is indicated by the 2-2 or 3-6 light code. A BIOS failure typically occurs due to misconfigurations in its settings or if the BIOS was not correctly flashed. To fix this problemreflash the BIOSand also reset its settings to default.
Even after updating the BIOS, if you are still seeing the power button flashes like earlier, the problem could be with the system board or the ROM. You must contact the Alienware service center in such a case.
