Hello and good start to the new year. I work in a netbook Acer Aspire One D255 with DDR3 motherboard PAV70 LA-6421P Rev: 1.0 whose problem is that only lights the LED power, turn the fan and also runs the hdd but the screen stays black. I tried to replace the chipset CG82NM10, but the problem persists. With its original ram DDR3 frequency 12800S the netbook comes on, but does not turn the hdd; with a DDR3 frequency 10600S the hdd runs, and for 3 seconds, the LED lights hdd, but nothing on the screen. I thought it might be a problem of bios. The chip mounted on the motherboard is a cFeon F16-100HIP. Having this chip parts, I tried to program it with a programmer Minipro 6.0 Model TL866A, but trying in every possible way, the binary file (PAV70D3.fd) does not load properly even if I select the chip on Minipro cFeon EN25F16 @ SOP8. I also tried to follow the method (USB stick formatted FAT and related file) suggested network using buttons FUN + ESC to the ignition, but the same thing, also because I believe that the keyboard is not even detected (even with USB keyboard). The PC does not respond to any commands from the keyboard. Of the original bios chip I picked the binary file. Any suggestions? Thank You |

I tried it with both MX25L512A @ SOP8 and W25Q16BV @ SOP8, but it's the same thing. I read somewhere that the cFeon F16 can be programmed in several different stages, but I do not know how it gets Solder again or replace the ene chip? |
