Inspiron 7500
750mhz PIII

When I try to power on I hear a brief second of drive/fan noise and
then nothing. I went thru the paces with Dell support on the phone
and they determined that I had either a bad board or cpu. I'd like to
try and fix this myself... I found the manual on Dells site for
disassembly. Before I start spending $$ on parts and go thru a trial
and error thing I thought I'd ask here for some guidance. I
disassembled down to the DC DC power board (04233T). I friend at work
said that this may be the problem. I can get one off Ebay for $12.
Should I try this first?

Thanks!

do you get any image on the screen? do you see any flashing pattern of the
status lights (power, hard disk activity lights). does it appear that the
system may be loading (hard disk activity) but you just do not see the
image? you could try connecting a external monitor to see if you get
anywhere. or, assuming it is not the screen, to troubleshoot, my approach
would start with removing as many unnecessary parts as possible; namely the
hard disk, modular cd, and any external devices (mouse, printers etc).
reseat the memory and try to boot from a floppy. if it still fails then
only thing left to try is to open up the machine and remove and reseat the
processor. try to boot again. if that fails then your trial/error approach
of swapping parts is all that you can do...

Make sure your computer has a properly charged battery or is plugged in
correctly..I had an older inspiron that would come on for a split second and
then go off..found out the charger had not been working properly and I was
attempting to start with a low battery. Of course something stupid like
that probably would not happen to other people

No image, no flashing pattern of lights (the power light comes on and stays
on but never the hard disk light). Dell had me remove all peripherals 1 by
1 (battery, drives, etc), reseat memory, video card, try an external
monitor. Thats when they figured it was either the board or the processor.
Theres a processor on Ebay now for $100

Anyone know the best place to find a board? Where do you guys buy parts?

Thanks!

Your symptom sounds like an improperly seated processor. I have seen this
on numerous MMC-1 and MMC-2 laptops. Have you reseated the processor, you
have to push hard with two fingers on the small circle indentions on the top
of the processor above the connector. Don't be afraid of pushing too hard.
It takes a lot of force. Be sure the laptop is on a flat and solid surface
and push hard. See Stonent's site here for the information about your
model.

see the 1st FAQ on the I7500 page.
