Occasionally there are instances where a customer is having intermittent issues with their laptop and they admittedly are at a loss as to why. This is a very good time to have a laptop technician look into the matter because in all honesty, the intermittent issues can be the toughest to diagnose and resolve.
Some people have issues such as this which are related to the hard drive. One key component for anyone is to keep the important stuff backed up by all means. Quite often the aforementioned intermittent laptop issues are going to be related to the hard drive. This is true of refurbished laptops under 200 just as it holds true for a brand new model. In our experience most hard drives provide many years of life, but as with any product produced there are always those which seem destined to be bad straight from the factory. Most of these luckily enough are going to fail very rapidly, and thus under warranty in most instances.
Some customers will have questions about RAID systems and this is fine in some cases. We have had business owners specifically request custom builds which use RAID, but for laptops the best bet is a constant and reliable data backup strategy. Even if the intermittent issues set in, as long as the information is retrievable then the computer hardware is an easily solved dilemma.
