This is not difficult. You just need to gently pull the front panel of the DVD drive. We look at the picture, and everything will be clear.
Let’s take a look at the bottom cover of the Acer Aspire 5741G laptop. Behind this cover are slots, with RAM inserted in it, a hard drive and a wireless Wi-Fi module.
