Old laptop upgrade configuration consultation?

1, notebook upgrade is more troublesome, because we should not only consider whether the hardware can be replaced, but also consider whether the original heat dissipation design can meet the new CPU work requirements.

2.CPU can consider replacing i5-2540M or i7-2640M which are both TDP 35W, the former is around 60 yuan, and the latter is 160 yuan (uneconomical).

3. You can add a 4GB DDR3- 1333 to the memory, or unplug the original 2GB and replace it with two 4GB DDR3- 1333. A 4GB DDR3- 1333 notebook memory is about 35 yuan.

4. The hard disk can be replaced by a solid-state hard disk with larger capacity, or if there is extra hard disk space, you can add another solid-state hard disk and install the system in the solid-state hard disk. The experience should be much better.

5. There is nothing to exchange for the rest.
