Re: t500 bios chip lifted pad issue

There are no circuit diagrams. You can check with an ohm meter.  You have the pinouts.  Only 8 pins are used so an 8-pin could be used if they are connected.

Re: t500 bios chip lifted pad issue

thansks.problem has been solved.i have used multimeter to track pcb ways and boom.The 8-pin portion inside the 16-pin chip location is directly connected to the 16-pin one,so the 8-pin is for the small version of the same chip.
