I got a laptop, it a solo 2150 version 1.5. It has a 600mhz mpga2 on it. When I upgrade it to a 800mhz, everything power up except the screen and it does not boot. I put the 600mhz back in and it boot. Then try with a 700mhz and it does the same thing as the 800mhz. I checked gateway and it same it support the 700mhz. Any suggestion will be helpful. Help!!

hi,
is your bios on the lappy flashed to the latest version from gateway? sometimes, have you tried a CMOS reset? (i'm not sure if a lappy can reset a CMOS...)
thanks

I flashed the bios to 17.52 for solo. It did the same thing as above. Any other idea would help.
Thanks
