[SOLVED]820-2796 MBA 11" 2010 - panic.

[Alan.L]

not liquid damage. board has no sign of liquid damage under a microscope.
board boot but kernel panic text messages before can load OSX any further.
ASD EFI passed everything but wont run memory test.

dead rams? can it be bios ?

i've already tried out of the case without airport card, ssd, trackpad etc..

Not worth bothering with as it could be anything, sorry.

 

[Alan.L]

duke, I found a liquid damage board, never been repair for £25. worth a shot repair and placing this into the case? if fixed, can i swap the bios chip to keep the old serial no.?

 

[dukefawks]

You can swap BIOSes on these without issue. If you want to play the Ebay garbage roulette then that is up to you, I wouldn't on a 7! year old machine.

 

[dukefawks]

There are 3 unused USB ports on the MCP. Check the board view if any can be accessed through test points.

 

[Alan.L]

no test points. guess have to live with 1 usb port.

 

[Alan.L]

yeah fuk BT, who will use it on a vintage MBA.


is it ok to connect USB_TPAD_CONN_P to USB_BT_P and USB_TPAD_CONN_N to USB_BT_N test points?

it doesnt have inductor like USB_LT1_P have "L4600" or original L5710.

 

[dukefawks]

Inductor is not critical. The traces to the BT connector should of course be cut.

 

[Alan.L]

that will be difficult. i think i'll just to mask out the airport card's pin with a kapton tape. i've already swapped the bios chip. will try masking out these two bt pin tomorrow. NN

 

[Alan.L]

mark this as SOLVED.....well by replacing with another board hahaha..
