Re: Powerbook 190 overclocking/detonation

[Josh Watson]

Hi all,

Hmm, well now that more than 1 person has reported this, i took a look at my own
190, and it has connections in exactly the same place (they are nicely soldered
though). Looks like it is a standard mod - just hand soldered on one and not on
the other.

Evan, I'd try the suggestions mentioned before for that 5300 with the same
problem (take the battery out and power it up, etc) as I think i *broke* my
190cs, whereas the others had a problem before.

Incidentally, surely Apple realised these 'books were going to just drop apart
when they built them - just took the keyboard, HDD and trackpad out to check
that, and two of the bits where the screws go in fell off! I hadn't even
overtightened or cross-screwed them!


I've given up on my dead 190cs (it was REA'd and everything :(), as its still
only good for making loud static and whistling noises. I feel my old 190 is
going to get a nice new case and screen...

This means i'll have most of a 190 in good parts. Anyone in the UK (or wanting
to pay postage to the US) want any of them?

Josh

Re: Powerbook 190 overclocking/detonation

Hi again,

I picked up a cheap-ish 190cs on eBay a while ago and earlier tonight tried to
upgrade it with an apple video card and IR board, and replace the RAM board. It
used to work slightly dodgily, so I thought the RAM board might have been fried.
However I got the old green light when I restarted it. I tried booting it
without the battery and it started to make an "interesting" burning plastic
smell... Anyway - it may well now be a gonner, but I took it apart to have a
look and it has several dodgy looking modifications to the motherboard. I wonder
if it has been overclocked unstabily - the mods are (i have no idea about
circuit diagrams in ASCII, so wish me luck):
Further to this, my 'book 190's just packed up with the exact same 
problem as this. I've had it for about a year now, so it's worked for a 
while.  But it has been sitting on the shelf for a couple of months - 
since I got a 5300. Could this period of hibernation have something to 
do with the problem perhaps?

Cheers,
Evan.

Yeah, i just wonder what they were trying to do to it??

I haven't got a digi camera myself, which was why I posted the ASCII pics. I'll
try and borrow one from a friend - I might be able to put some pics up on the
web tomorrow night.

A resistor with 104 ( or h0|  :) ) on it
Theres also a couple of dodgy connections on the bottom from CX03 to C314.
Is this a standard mod? It looks like a monkey did some of it?

Also, when I now turn it on (its outside the case), I just get a radio
interference noise down the headphones, which suggests the PRAM might actually
be dead... the burning smell suggests worse though
Cheers for any suggestions as to what someones done to this 'book?
