We have seen many cases where several Dell Inspiron 15R owners have found that their motherboard had given up on them. This is not an isolated incident because we had a Dell laptop and the motherboard went twice on us.
In the end it became frustrating and so we located a better quality motherboard and proceeded to replace it, which is not for the faint-hearted. This is the same as what a Dell Inspiron 15R N5110 owner had to go through, but thankfully has provided a video as a way to guide you through the process.
If you take your time and study the video then a Dell Inspiron 15R laptop motherboard replacement is not as hard as you would think, but again you need to prepare yourself because it can be time consuming — so make certain you don not have kids running about.
Before you attempt this repair we advise you to have a few tools ready, which include 1/8-inch Flat Head & Phillips screwdrivers. The video consist of several steps, and we advise you if you are planning to upgrade the hard drive or memory then do it at the same time.
It should take you about an hour to undertake this job, but if you have never done something like this before, then maybe you should allow at least double that.
