Re: Laptop Motherboard Repair
chevelle_nut
I wont have access to my digital camera until Monday, but this board is totally different from the dv6000 and 9000 i have seen before. Can u elaborate more on your repair? Do you have a schematic available? Can you recommend a replacement for the 4856a?
Thanks

Re: Laptop Motherboard Repair
I have a DV6500 with no power on from battery or a/c. I do have blue ring around a/c adapter. The mosfet on the top of the board near the battery connector marked pq30 is a 4856a. I measured this ic in diode mode and got 450 and 0. I have 18.5v on this ic but not on the bottom one near the power in connector. That ic is marked pq3 6679gm it reads 430 and 93. I think i will replace both, but i cant find a replacement for the 4856a. Does anyone have any suggestions on a possible replacement for the 4856a?

Case fans
I have a mini-itx case that gets extremely hot inside...i have installed a couple of 40mm fans but they keep failing within a month because of dust or bearing failure. Does anyone have a suggestion on replacement fans? thanks
