Notebook computers are notoriously
resistant to CPU upgrade options, mainly due to space limitations and
model-specific motherboard (hence BIOS) designs. Your HP Omnibook 4100 is
no exception. Unfortunately, pushing its native 266MHz Pentium-II up to
500MHz would require a magic wand.
As you can see on our Pentium-II stats
page, your CPU upgrade options are limited by what can actually fit
into the Mobile Module connector on your motherboard. In the case of the
Omnibook, the fastest CPU that would fit is a 300MHz Pentium-II. If you
check our CPU Comparator, you will see the
relative increase in speed would be less than about 10%.
A memory
upgrade
to the 96MB max, as specified by HP's
Product Spec Guide, would be your best bet for a performance increase.
