It is annoying and bothersome when your machine goes dead due to laptop adapter problems. In most cases, laptop adapter problems become apparent when plugging in the laptop does not cause it to come to life as normal. The first step in determining the reason for your laptop adapter problems is looking at the status LED. If you don’t see any light at all, see if the cord has simply worked loose from the transformer and the outlet. If everything appears to be in order, you likely have a defective adapter.
In some cases, troubleshooting laptop adapter problems is a lot more complicated than that. Sometimes the problem may lie with the power cord, which is a common issue with a surprising number of laptop brands and models. Most users seem to agree that laptop connectors of the “L” variety are typically the most robust and least likely to fail.
You may also notice some changes in the status LED when you move the power cord around. In some cases, you may have to keep the cord in a certain position in order for the laptop to receive power normally. In fact, some users have become quite imaginative with keeping the cord positioned just the right way, although these fixes are of course only temporary and you will have to implement some more long term measures.
When the power connector inside the laptop is actually damaged, then it is a more serious problem . In such situations, your best bet is to take your laptop in for servicing. This is of course the best possible course of action if your laptop is still under warranty, but the problem is serious enough that you will want to seek qualified technical assistance either way. Remember that there are some potentially lethal voltages lurking around under the hood and the interior of a laptop is no place to be sticking a screwdriver in if you don’t know what you are doing. So it's better if you take it to a qualified technician.
