Crappy 1st Gen USB.. 10mbps woowooo :P
really? i'm pretty sure it's USB2.0.
the kids' laptop, a 2005 Gateway MX6030, suffered a 4th-degree burn and is dead. upon examination, a chip is found to have burned, possibly a voltage regulator (but there is no heat sink on it). the chip is labeled 4407, but i have no idea what it is exactly, even though i'm an electrical engineer. i don't even recognize the manufacturer's logo -- it looks like a capital script "P." shame on me!
after checking a few parts catalogs, 4407 is still nowhere to be found. this laptop is made in China, and chances are this part is from a local supplier. they do that all the time to save on cost.
if there is a hardware engineer out there who can identify the chip, i'd appreciate it very much. needless to say, a schematic or BOM (bill of materials) of the motherboard would be really helpful.
UPDATE (8/03/2008) a closer look at the connections to this component reveals that it's a 3-terminal device -- the bottom 4 pins (5, 6, 7, 8) are tied together, and 3 of the top pins (1, 2, 3) are tied together. this means it's certainly an analog device passing through quite a bit of power, most likely part of a voltage regulator. if that's the case, i might be able to find substitutes, as the specs of such devices have quite a bit of leeway, i think.

Conclusion: beware of Gateway laptop and
«made in China» label :)

yeah, it's not good.
well, not enough to fix it. i just don't
know where to find such a part.
well, Gateway is easy to avoid, but Made in
China is practically impossible.

Heheh i agree on your second statement as to
my observations... :)

Oooh, good luck! You might be able to find a
whole mbd, but finding that IC would be
nearly impossible! Did the board delaminate
under the chip?

omg... sorry to hear that... my mom's
notebook burnt too recently... she usually
leaves it on throughout the day. she said
she suddenly saw some smoke coming out from
the notebook, got scared, and unplug it right

thanks for the good-luck wish! i need it.
the board didn't de-laminate under the chip.
i didn't realize it would be so difficult to
find such a part. in my previous job, i
could simply take the board to a hardware
engineer, and i'm sure someone would be able
to identify the chip and possibly replace it
for me. now i don't have access to such
knowledge anymore. the whole motherboard
would cost half of what i paid for the
laptop, so it's not worth it.
it's ok. computers die. i hope your mom's
notebook survived, but usually smoke is not a
good sign. my work laptop is also on all day
long since it's my only computer at work.
but, it's got a docking station, and it's
nice to have two monitors. :-)
actually Lenovos are good. my work laptop
and my other home laptop are Lenovos, and
there is no problem so far. what i like
about them is they run really cool. the
problems i've had are with HPs and Gateways,
and always related to the power supply. i
just don't like the way the power sockets are
designed -- too flimsy.

I searched "Gateway MX6030" on ebay
and found a sys board for about $51 with
shipping. Here . It has power issues but if you could get
that part off of it you would be back in
business.

thanks for searching! i also found the same
item, but it's got power issues, and it might
have the same problem.
