    Lenovo G505 (AMD E1) notebook - power on problem

    Hi all,
    My friend told me that the notebook developed a problem after 15 days of purchase, the notebook won't boot anymore, it turns on (the fan starts then stops) but simply won't boot, and when the APU becomes hot the fan starts cooling as usual.
    I noticed if you pull out the RAM and power on the notebook guess what! Beep, beep, beep … that means memory power sequence is good, battery charging normally.
    Reset methods, electrostatic discharge ... won't work, CMOS Battery is good (3.10V).
    I tried to flash the BIOS via CRISIS disk method but it didn't work (plug-in the flash drive -tried all the USB ports-, hold down FN+B or FN+R -tried both-, plug-in AC adapter while holding the previous combination of keys, press the power button, the notebook powers on with FAN at full speed for about 5 seconds then shuts down itself and so on for 5-6 times then it shuts down completely -USB not recognized or the BIOS's filename is not matched; I don't now).
    Anyway, I've got a BIOS programmer (XELTEK SUPERPRO 500P along with a TSOP 20 Adapter), flashed the BIOS successfully (at first, I didn't get the right orientation of the CHIP on the programming adapter; XELTEK software tells me there is a misplaced PINs, wrong orientation...etc., until I got it right and flashed it successfully) but the problem persists and a new problem raised, now if I try to hold down FN+B or FN+R and plug-in AC adapter or the battery and press the power button the notebook starts normally (won't boot of course) which means even the CRISIS recovery not responding and the FAN won't cool down the APU (like it was before flashing the BIOS) even when it gets hot, also no beeps when you pull out the RAM. Reflashed it again but no luck.
    Did I damage the BIOS? And if so; how did it flashed successfully? Any suggestions! thanks in advance.
    I have no experience with BIOS Programmers and the notebook has no warranty.

    Did you save the old bios bin before reflash it, it look to me that you have a second problem now in place from the first one, i think the first one was NB failty, you could reflow it and see.

        You can try to find the bios here or ask and look if someone have that,
        by NB i mean Gpu.

          NB is north bridge, in that case you mean APU (everything is combined now )

            Did you reflow it before starting work at the bios.

              No, I didn't even think about it, maybe you're right since the APU package is FT1 BGA, I'll try to flash another BIOS version (the original one) and report back.

                  Gpu failure, Gpu inside the Cpu chipset, just try reflow or reballed
