No, laptop motherboards has no jumpers usually. If you think about overclocking you can try any software.

Can you do a cpu upgrade on Acer Travelmate 2480-2968? If so what type of intel CPU will work on this machine?

The following CPUs are supported by the Acer TravelMate 2480:
Intel Celeron M processor 410/420/430/440/450 (1 MB L2 cache, 1.46/1.60/1.73/1.86/2 GHz, 533 MHz FSB) or higher.

So, based upon the speed of the CPU you currently have, you can decide whether you need a CPU upgrade or not.

Ax4per with 1.8GHz does not recognize new 2.8GHz processor. Socket 478. BIOS is current. Is it not plug and play?


Does it POST and can you get into the BIOS? You need to set the FSB to 133MHz and the Ratio to 21x.

(I am assuming you did install the CPU correctly and installed the fan.)

If you can't get into the BIOS, you may need to reset it using JP14 on the motherboard.

Turn OFF power. Remove the AC power cord. Hold the power button in for 5 to 10 seconds. (This is done to discharge any capacitors.) JP14 normally is on Pins 1 and 2. Place the jumper on Pins 2 and 3 for approx. 10 seconds. Then place it back on pins 1 and 2. Connect the power cord and turn it on. This will set all the BIOS settiings to default and you should be able to set the FSB and Ratio.

Do you have a manual for the MB? you can get it from:

Thanks for using Fixya.

Cpu upgrade

To upgrade the cpu, you will still need to use the same type of cpu. A socket 478 motherboard will not work with a socket 775 processor. The pin configuration is different.
