may be help or just for nostalgic

Hi all,
I have this old macbook which I am trying to repair for nostalgic reasons
The fan does not spin until the MB overheats and shuts down.
The fan gets 5V but there is no PWM on pin 3. The same with the fan unplugged, no PWM on pin 3. The fan shows some glimpse of activity every 5 seconds. Sometimes it spins for half a revolution and that's it.
From the schematics (obtained from this forum, THANKS!) I see there is a mosfet getting signal from the SMC. The mosfet gets 3.3V but there is no input - well, there is 3.3V. I removed the mosfet to see... -
This nostalgic American made...Bose which from Goodwill has no display.

I really don't know which caps to change, so I use ESR meter found this 2 caps. (Pic 7)
One question, no display how come you know is display problem, Is the power turn on or not ? By use this UK made meter ( if I am right?) in Pic 4. I put in current mode (this meter has 4 digits current display better than anyone else.) to diagnostic where the power is on or off.

Hello all
I'm new to the forums.
I am trying to troubleshoot an old LGA775 Asus P5P800-VM. This MB comes from an old 35mm Cinema sound processor which I am collecting for nostalgic reasons! As this is a custom system, it may work with another board or it may not. If I cannot fix it I'll get another identical one on the internet but for now I am doing my best to fix it.
Little history.
- System failed to boot intermittently. I thought it was one of the expansion boards but in the end it failed to boot altogether even with nothing connected.... -
The more time passes, the more nostalgic I get with old hardware. Video cards and motherboards tend to be my weak spot. As such, I often scavenge eBay for old PC hardware, especially anything with bad caps or in need of similar minor repair.
For today's consideration, I have a popular low-end card from back in the early 2000's: an nVidia GeForce FX5200. This one is the BFG Tech. Asylum take on the card, with 256 MB of DDR RAM running at 400 MHz and 128-bit bus (vs. 64-128 MB and 64-bit bus on many of the cheaper versions.)
I think it's easy... -
Hi everyone,
I have some DFI nF4 boards coming in to try and relieve some nostalgic times. A few of the boards have bulging caps and I'd like to just recap the entire boards to make a fun project of several weekends.
I am not entirely new to this replacing caps thing, having swapped out some bad caps on original Xbox motherboards while completing my EE undergrad.
I am curious if there are any electrical issues (yes my undergrad is EE but I mostly work in CPU logic design and OS/firmware now so... it's been a while hah) with replacing all caps on DFI nF4 motherboards...
