I don't have its replacement are there any alternatives. I am not good at finding alternatives ...

Part | Marking Code | Vendor

PT3661-BB = 661 Prolific
EM-6781-T3 = ??? AKM
AH180N = K9 Diodes
APX9131 = X31X Anpec
APX9132 = X32X Anpec
MH248BESO = 248x MST/magnesensor
OCH1691WAD = 251x ???
AH9249NTR-G1 = GJ9 Diodes or BCD

mostly when i'm seeking component for quanta I will also looking at quanta's donor board and same brand. after reading lots datasheet and compare HD image board, seem they were all use same component for any brand and manufacturer.

Quanta donor board with label on PCB MR1 or HE1
Wistron donor board LID1
Compal / inventec donor board Ux/Uxx/Uxxx

Thanks you Guys, your posts helped me with the same problem... My troubles was with bad keyboard, but i was not able to start notebook manualy by shorting of last two pins of keyboard connector. Dead, MR1 was the reason of my troubles... for now i have solved it by shorting MR1, but i will try to order new sensor. Thanks.
