Instead of beep codes, errors are indicated via the bicolor Power Button LED. The power and battery-status light blinks red and blue along with beep codes indicating failures. For example, the power and battery-status light blinks red two times followed by a pause, and then blinks blue three times followed by a pause. This 2,3 pattern continues until the computer is turned off indicating no memory or RAM is detected.
NOTE: The diagnostic pattern will consist of a two digit number being represented by a first group of LED blinks (1 through 9) in red, followed by a 1.5 second pause with the LED off, and then a second group of LED blinks (1 through 9) in blue. This is then followed by a three second pause, with the LED off, before repeating over again. Each LED blink takes 0.5 seconds.
The system will not shutdown when displaying the Diagnostic Error Codes.
Diagnostic Error Codes will always supersede any other use of the LED. For instance, on Notebooks, battery codes for Low Battery or Battery Failure situations will not be displayed when Diagnostic Error Codes are being displayed.

So looks like a chipset/motherboard issue. You can try a power drain: unplug every external device (including the power cord), open the system and disconnect the battery cable (you can use this video as a reference Sec 50), then hold the power button for around a minute for all the power to be drained.
You can also try a clear cmos battery, use this video as a reference.

Hi kaiserpunk,
Simulations/Diagnostics: Diagnostic LED
