    I have a very strange problem with my HP Pavilion dv7. The problem started out with a black screen coming up saying no boot device found and the hard drive was making a loud noise. I replace the hard drive and now the noise is gone but a new problem was discover. Sometimes during shut down instead of it shutting down completely it will go to that black screen saying no boot device found. Also to when pulling out the power cord I get a white screen. I tried plugging in a external monitor by vga while having the white screen and the external monitor displayed fine. When I unplug the monitor and plug the power cord back in sometimes the screen came back up find and other times after unplugging the monitor and plugging the power cord in the system crashed and either says no boot device found or brings up the diagnostics screen where you can do a system restore for windows to boot up again. Sometimes I don't have any trouble shutting down the computer and I am wondering if it only does it when it gets hot. Just about every time when I unplug the power I get the white screen. Any help resolving this problem or some good advice would be appreciated. I hope I posted this in the right section. I don't think its a software issue. I posted this somewhere else and I think it got place in the wrong place on the forum. Couldn't figure out how to delete the old post.

    Those dv7s are notorious for failing. It probably has an AMD chip in it. They get hot and some pins disconnect from the board.

    I'm thinking a possible overheating issue as well.

    I haven't used a temperature monitoring program in a long time, so I can't recommend one. I'm sure another member will have a suggestion for one.

    Another thing I discover was if you turn it on without plugging the power cable up it will display a white screen. When you plug the power cable up it will display no boot device found. If you hold down the power and try to turn it back on again with the power plug in it goes to the desktop.

    Those sure are weird issues.

    Try this:

    Remove the battery and unplug the power cable. Now hold down the power button for about 30 seconds. Release the power button, plug in the power cable, but leave the battery out. Does it boot up and run ok now?

    It looks like it works fine with the battery out and holding the power button down. But it still does it with the battery in and charger unplugged. The only way to keep it up and going is plug in with power instead of using the battery

    Laptop batteries generally last between 2 and 5 years. If you use it with battery a lot, the time is shorter. If not too much, longer.

    In fact, I have a 7" eeepc purchased in Jan 2008 that will still run on battery alone for over an hour. I think when it was new, it might have been 3 hours on battery. (10+ years) Since I have no hopes of getting a battery for a 10 year old netbook, I'd either plug it in or carry a large portable battery with me. (6000 mAh)

    An Acer Aspire One purchased in August 2011 required a new battery at the beginning of 2017. ( a bit over 5 years)

    I will purchased a new battery and let you know. It may take a little bit because of the mail and stuff to get it deliver
