I had a Dell laptop with Win7 that the user was complaining that the screen was going black. I quickly realized it was not the screen, but a setting. When you put your hands on the keyboard, the screen would dim. If you put your finger over the sensor, it would (obviously) go black. I hunted around for quite a while, but found a simple fix:
This turned the auto-dim function on and off. I am thinking that he inadvertently set it when he was trying to change his resolution.
I attended an IT career school in 2001 and earned my A+, NET+, and Cisco certs. Immediately after that I worked for Convergys supporting Cisco products. It was a team environment, and I enjoyed it a lot. As that job was sent offshore, I started working for Qwest. I quickly adapted to the properity ticketing software, and a call center environment. As I grew in education and certifications, I changed jobs to offer more opportunity. At Ultradent, I earned my MCSA and MCITP certifications. I also was responsible for increasingly complex projects. I was part of the team that implemented the ITIL process.
