No! it is one I purchased before thinking whether or not it will work with the Mobo listed. Neither CPU is soldered to the Mobo. Rihgt now he Current CPU is a AMD MK-36 2.0GHz single core. The Motherboard (I just found out is not made by Acer, but ATI) MBABK02001 lists the CPU support as AMD Turion 64x2 TL-50 or Higher. I'm asking can I upgrade the CPU from the AMD MK-36 2.0 single core to the AMD TL-68 2.4 dual core. I know the Next higher single core is the AMD MK-38 CPU 2.1 and yes it would be nice to just get another Laptop, but Money is an issue right now and I like tinkering with the laptop if but to know with help, it can be repaired. I sure thank you for your input.
