HP mini 210 - no image, no VCC_CORE

[sicilianul]

Hello,

As the title says - I have a hp mini 210 which powers on, everything looks good - excepts vcc core. It's starting very slowly at 0.1v. 5V, 3.3V, 1.8V, 1.5V bios are present.

I tried a reflow but without effect. Tried reflash 3 BIOSes - same problem.

It's any chance of any problem instead dead CPU ?

Pin 5,6,7 (S1, D2) = 62.4ohm
Pin 8 (G1) = ∞ ohm. Diode mode with + to ground = .601
Pin 1,2 (D1) = ∞ ohm. Diode mode with + to ground = .465
Pin 3 (G2) = ∞ ohm. Diode mode with + to ground = .390
