I have a HP Pavilion dv7. It is nearly 13 *months* old. When it was 11 months old it wouldn't boot and I ran the hard drive test in BIOS, it failed. Hence HP over-nighted a novel hard drive.
Later 16 days the guarantee ran out it began including a novel trouble. Above 50% of the time when I turn it on it sits with all lights on but doesn't boot up. All the lights they gradually come on when you turn it on are on. But it doesn't boot. I hear the DVD drive spin up but don't hear the hard drive. The display is black. The CAPS and NUM lock lights blink at the same time one every couple seconds I think. I didn't time it.
Finally the laptop will boot. I am writing this post on the dv7. This morning I turning it on at 9-ish. At 12-ish it determined to bring windows up. I called 3 computer repair places. One lay said this was common lay with the dv7, the CPU board was toast. Another guy said he could substitute it but it wouldn't be worth it.
Another trouble I have encountered is sometimes when the cord is not plugged in and I put it rear on the battery icon will say "plugged in not charging". I turn it off and disconnect the cord, take out the battery and tut the rear together and reboot. Normally it begins working.
Worst part is I actually as this laptop. Hard drive is slow (5400). But as well that, it isn't a bad one. Not a powerhouse. Just it was doing all right until it began caring out three hours to determine to start. Any ideas?
