| Portable won't boot, even after recap |
Posted by: dan6457 on 2013-12-30 07:13:45
Hi guys,
I have just joined the forum. It looks like there is some great stuff on here.
I have recently tried to get a macintosh portable running. It wouldn't boot so I stripped it down and replaced all the capacitors. The board was then washed in IPA, left to dry and the computer re-assembled. I am running it from a new battery. However it still won't boot up. Rather than explain the symptoms I have uploaded a video showing what it does.
Any help will be very much appreciated.
Thanks.

Well you did better than I did when it comes to re-capping, I still don't get a boot chime! I would pull not only the RAM card as suggested, but all I/O devices. If it works, hook up one at a time. Just to rule out any unusual power draws, etc.

I've tried it with nothing connected except the keyboard and mouse, still exactly the same...

The problem with the portables is, people (before your conquest) ran them with out a main battery, with BAD CAPS - with powerbook 2.0a / 3.0a power packsā¦ cooking the living crap out of them.

What components are likely to be cooked and can they be replaced?

who knows. find out and let us all know.

edit:
Sorry if i sound a little negative towards the portableā¦ that is because i'm feeling a little negative towards them at the moment.
as we find out what the fixes are for the 5120 and the 5126 it would be really fantastic if we could make a table of what the issue wasā¦ and what was the solution that fixed it.
maybe pictures too?
i think many issues stem front the U1M Hybrid board. -- for the 5120.
next i think for both the 5120 and the 5126, the q14,q15,q16,q20 failures could be a place to start lookingā¦.
for the dead dead boardsā¦
other wise for issues like yours you can look up the sad mac codeā¦ but more then likely its a serious issueā¦ CPU GLU or MISC GLU that gets nuked.

(for me)
The 840av and the Portable seem to have about the same success rate after a recap.
The SE/30 is right behind those.
