I have a 2-year old HP dv4 laptop that was hung-up with a blank screen. It would not boot, nor could I get any control by using Esc, F8 or F10. I took it to where it was purchased (Best Buy), and they said it could be any H/W component. If they took it, it would be shipped out to a Repair Depot, and it would not be back for at least four weeks. So I did not leave my computer there.
I looked on-line for a local repair service in south Orange County and found Magnum Computers. The ad said they will come to your home/business, 24/7, experienced and certified, and the reviews on multiple web sites were very good. So I took a chance on them.
The repairman came out to my house on a Saturday (at no cost), evaluated my laptop, and told me he was 100% sure it was the motherboard. He said the cost for a new motherboard was about $300, and the labor would be about $100, and he would have the laptop ready by Wednesday. All of this was true, and I have a working laptop again (with a new one year HP warranty on the motherboard). It is hard to find a knowledgeable, honest, and prompt service person, but Magnum Computers is just that.
