Hi, I have an M14x R2 with 7 beeps error, when I boot it I get the 7 beeps and the speaker sounds like it doesn't have much power, only some of the keyboard lights light up, and change colours as well as dim each time a beep sounds, would there be some kind of power issue? Thanks
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

try another CPU if it is not soldered on the board.
does it display any picture on the screen?

after turning on, measure voltage on PL502.

please upload the schematics file of the motherboard, so we can help you.
or report the board ID.

Originally posted by caspian View Postso it does not have CPU_Vcore. thus, the CPU may be fine.
now measure voltage on other coils including PL202, PL303, PL403 , PL504 , PL604.
it takes time to reach a conclusion.
PL303 - 0.5mV
PL403 - 0.3mV
PL504 - 0V
PL604 - 0V
