The computer I bought during the pandemic in 2020 had an entry level motherboard: an ASRock A320M-HDV R4.0 with limited tuning options in the UEFI BIOS. There was nothing wrong with it (after I updated its BIOS to solve some random video games issues), but I had always wanted to replace it with a model with more tuning options. I didn’t want to spend a lot of money, so I ended purchasing a refurbished Gigabyte B450M DS3H motherboard (36€). I have documented step by step in this tutorial how I replaced the original motherboard of the computer by the new one in case you need to do something similar.
I had recently purchased a cheap Acer Veriton ES2730G desktop computer on eBay (76.50 €). Everything was working fine but I wanted to perform some upgrades to improve its performance and to give it a second life. I decided to share my experience and you will find here a series of tutorials describing how I did it step by step and some advices in case you want to do something similar.
This page is part of a series of tutorials about upgrading the components of a second hand PC in order to give it a second life.
In this tutorial I will describe step by step how I added a RAM module to the computer (an Acer Veriton ES2730G here but the procedure would be similar for an other PC) in case you need to do something similar.
I had recently purchased a cheap Acer Veriton ES2730G desktop computer on eBay. Everything was working fine except that there was a CMOS error every time I removed and reconnected the power supply unit (PSU) cable.
The solution was to replace the CMOS battery and I am going to describe step by step how I did it in this tutorial.
My trusty MacBook pro 15 (mid 2014 model) was slowly dying with all the symptoms of a swollen battery: the case was warm, the fans were blowing at full speed even when the laptop was not performing any CPU consuming tasks, the trackpad was not working anymore and I could even see that it’s back was not flat anymore. I was mostly using it connected to a screen, with a wireless trackpad and keyboard, so it was not such a big issue but I was starting to fear the battery would explode or catch fire.
