This appears to be a blue LED hardware issue. The blue power LED has probably either loosened at a solder joint or become defective. The orange power LED (blinking while in sleep mode) is still OK.  Jack E/NJ

Did you manage to fix it?

Depending on the full model number, the LED or power button board would need to be replaced. Jack E/NJ

Your model seems to have two blue power LED indicators. A blue LED for the power key itself  on the power buttton board. And also a blue power on LED on the right side. Have one or both blue power indicator LEDs failed? Jack E/NJ

Yes it has two leds one for battery status is good blue when it’s fully charged and orange while charging but the problem as following the other led refers to pc status it should be blue as long as it is on but as mentioned it turned to orange in sleep mode .. so my problem is with the blue color I don’t know if it is a diode problem or the signal not deliver to front panel

Sorry. Not what I mean. Not the battery LED.

The power button itself has a blue LED when fully powered. And the power status LED on the right side has a blue LED when fully powered (not sleep). Are both the power button and power status lit? (Not battery LED) What color are both power LEDs when fully powered? (not sleep) Jack E/NJ

No this model does not have a led on the power button it has only two leds on the right side of the metal body

Unlit always off
