I think you can add CPU although many laptop/netbook
CPUs are soldered
in. I just replaced the motherboard in my IBM T41 (actually with a T42
mother board) and much to my surprise the CPU was socketed. Perhaps
because IBM gave 3-year warranties with these beasts.
If it's not a BGA package, then it cam be unsodlered and replaced with
hand tools. For some odd reason most people seem to think soldering is
difficult/immpossible. I don't get this.

There is some hope. A search on E-Bay reveals that
many folks are
selling capacitor kits for a wide range of gear. The trouble is we are
I've yet to see oen for acomputer motherboard, but I've not really looked.
lazy and if folks have enough money then its easier
and nicer to bin the
old one and get a new one. Perhaps the turn-down will change attitudes
Mybe for you. Actually ,for me it;'s less work to fix the problem than to
have to carry a new <foo? home or wair around for some random parcel
company to deliver one.
in Europe but I think not. I may be old fahsioned but
I can't see how a
country can exist on shopping and finance "industry" which is what it
seems my (UK) government thinks. From what I can see any profit a bank
makes is money that could have been spent on tangible assets ....
You and me both...
I have had a new PSU in my 42" TV , I assume because of caps blowing but
I think I've mentioned this bfore. Our LCD TV contains 2 PCBs and the LCD
panel. The serivce manual doesn't incldue any infromation o nthe PSU, you
swap the board when it fails. But it contains full schematics nad parts
lists for the signal board, even though ti contians a couple of BGA
packages and some fine-pitch PQFPs. And the only information is the
schematic, no waveforms or anyhting liek that. I am not looking forward
to sorting that out.
it was covered under warranty. I have an LCD computer
display that has
had the caps re-done. Some times it doesn't work. I lost an ADSL router
that way, but something else must have been damaged. However replacing
the caps on a motherboard isn't as straight forward as it sounds.
Getting the old ones out and getting holes clean enough to get the new
ones in is challenging. My usual trick of using propelling pencil lead
didn't work and I eventually resorted to a drill bit in a pin vice.
However one CPU board I did for a friend
Doesn;'t the old trick of melting the sodler with a good iron on one side
and sucking on the other work? It's cleared every hole I've ever needed
to (and it gets darn tedious when you are upgradnin a part-populated
wave-sodlered RAM board and need to clear out a few hundred holes).
