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!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.

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?Seen in my contacts' photos. (? )

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.

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.
