zenith z-star cpu upgrade

hi all, I have an old notebook and i want to upgrade cpu. I find a
ciryx gp100 100mhz socket3 cpu. this cpu need 3,45 volt but the old
cpu uses 5 volt. I don't know where(if there are any) the jumper to
select voltage is on the mainboard. I don't know the type of mb and
the mainboard code for looking on the net for more info. any
suggestions? thanks in advance for your replies. Bye

Look for a web blog or discussion group that focuses upon old laptops like
yours.

If your laptop has a genuine 'socket 3', you could use an interposer
from a variety of companies such as Evergreen, Powerleap, etc. I have
a number of small 486 machines upgraded to Pentium (up to 166 MHz)
using interposers and AMD or Cyrix cpus. The interposer has active
circuitry to provide cpu voltages and glue logic. Make sure your
laptop has sufficient clearance to accommodate the height of an
interposer -> cpu -> heatsink(fan, cooling pipe, etc.).

Regards,

Why even bother? Unless you have the CPU laying around, it's hardly worth
the effort. You can get a far more capable laptop for relatively little
money these days.
