Re: motherboard short repair question
pics are taken with my iphone. I don't have a different camera to take them with the are as clear as I could get.
I think that one was pc47 not pc 50. I found a schematic and pc50 shows 6.3v when the cap tested 19-20v and pc47 is 25v...Last edited by jeff6666p; 05-18-2015, 05:49 PM.Leave a comment:

motherboard short repair question
I got a bad laptop that was only turning on sometimes and would turn it self off. I was checking out the capacitors and one was staying at 2.3 volts when it should of been 6.4v. I tried linking it with a different one and it started working but while testing I accidentally move wire and it touched a different cap and shorted out and has no power now. If I replace that cap should the computer turn on again. If I post pics of the two caps will someone on here be able to tell me what the are so I can buy the right ones. Thank you -

Re: Soldering question
I got my pump in today. I put some new solder on the hole with the leg stuck then used the pump, did it on both sides and the leg came out. I did it with the 25w one I have now the hakko one wont be in until tomorrow. What is the way to get ic chips off?Leave a comment:

Re: Soldering question
So just set it to 310 heat up the solder then using a pump will remove the leg?...Leave a comment:
