Re: LG C500 2 sec shuts off

I optained the file for LG C500 Pegatron H46Y rev 2.1 from Another website and proven to be working according tp replies. Check if you have the same model as above. The model name is given as file name inside RAR file. If your MB has Another name/ rev then it won't work. How did you flash the EC??

Would recommend trying another bios chip and flash it with a known good programmer.

Re: LG C500 2 sec shuts off

Thanks for the response tibd at first i flashed the main with your file laptop turns on automatically fan spinning fast but no display after that i flashed the EC with your file because the same size with my original 64kb i flashed with miniprotl886cs programmer and soldered back when i plugged in laptop nw no power and led lights.it is possible the ec problem?i checkex the motherboard is the same with your file H46y rev 2.1.

Re: LG C500 2 sec shuts off

Main bios is winbond W25Q32bv and ec is mx25l512 i checked the voltage on this chip voltage is correct. I dont have another the same chip to replace

Re: LG C500 2 sec shuts off

I had a pair of these 25q32 failing. they seemed to be programmable but never worked, changing them revived the MBs, just a though that it might be so but very hard to say. As i mentioned the dumps are not from som device i own but from a very good website that i never had problem with.
