So I recently picked up a compaq portable II. Its not in the best condition, and the last couple owners clearly didnt love this machine. After opening it to check for debris, I powered it on. Got a high pitched rythmic sound, must be a cap trying to charge. I removed all the cards and tried again, so now the system fan will pulse or vibrate but not spin. I decided to put the cards back in and try again. two tantalum caps and a resistor blew. One cap on the cga card, one cap on the system board and a resistor on the power supply. I can see what the value of the caps on the cga card and mobo are although Im better with electrolytic caps, I cant make out the value of these ceramics. See attached photos.
cga card cap is 106 16K
motherboard cap is 10-.15 +m2
The resistor in the ps is so burnt I can only tell the outer color bar is gold on one side orange on the other, (possibly red)
if it is orange on one side and gold on the other, there are two other nearby resistors with a 300ohm value, see photo
Anyway, I want to order some of these caps to replace them all, and its tough to tell what resistor I need. If anyone can lend a hand at helping me restore this old compaq 286 portable it would be greatly appreciated.
