CPU Upgrading
Important! only undergo this procedure if you know exactly what you are doing!
WARNING!!!
Pentium 1's have different voltage ratings! the original CPU from my laptop was an sx969 and had a core voltage of 3.3 volts.
different Pentium 1's may have differnet voltages e.g. 3.1 of 2.9 volts. DO NOT, DO NOT install a lower voltage processor
into a higher voltage socket! you may well destroy the motherboard and the processor! YOU HAVE BEEN WARNED!!!
1. dismantle
the laptop until you have accses to the cpu settings dip switch and the processor itself (see the
disassembly guide) (the processor is the big black block of metal with a fan on top)
2. VERY GENTLY, with a flathead screw driver,
prise the heatsink off of the processor ( the best way to do this is with a large tip that will touch the heatsink and the
pcb underneath ( the pcb is the little white square that sits on top of the motherboard ). insert the screwdriver and twist
it slowly until the heatsink comes away from the processor.
3. VERY GENTLY , with a flathead screwdriver prise the
cpu from its socket ( insert the screwdriver between the processor and its socket and twist the screwdriver. do this all the
way around until the cpu pops out in you hands ).
4. Research you cpu. enter a five digit code which starts with s
and is found on the cpu (e.g. sx969) into google and find out the core voltage.
5. Replace you cpu with one with exactly
the same core voltage.
6. set the dip swiches accordingly (see the
dip switch settings page)
7. Push the heatsink and fan onto the top of the new processor.
8. Reassemble the rest of the laptop
(see the
disassembly guide).
9. Test your setup (run some intensive stuff, cpu test software etc etc, and monitor the cpu temperature).
10.
If all is well your done, if not try a better cooler or a different processor.
