I'd like to share my bit of frustration with a HP laptop. It has a slow 5400 rpm hard disk coupled with a Celeron N2830. While it does any job I ever asked it, the experience of using it was tinted due to its slowness of responsiveness. Booting takes more than 2 minutes, opening Firefox many seconds and browsing the web is sluggish. This is why I wanted to buy a cheap Kingston SSD to replace the hard disk, which is the main bottleneck (even more so than the processor!). But before spending 40 euros on the SSD, I wanted to be sure the hard disk had a 2.5 inches form factor, because the documentation for that laptop model is non existent (yeah, a true HP laptop, made in Brazil, without official doc). So I tried to open it, and after about 2 hours I gave up. It's as if the electronic board was soldered to the plastic cover. I followed several youtube videos, including one of a very similar model, but my laptop was different and would definitely not behave as anything I've seen on youtube. So, its lifetime will be the one of the hard disk I suppose. When it fails, I'll retry to open it but I may end up splitting it in half by using excessive force. Enjoy.
