I have HP Compaq Presario F500. Without battery or AC it won't do anything - No sound - no screen - silent and black. With battery in I will get a blue power light and orange wireless light - but no sound - no screen - silent and black screen. What is the problem - I'm sitting down - give it to me straight.

Thanks - now...I willing to take this bad boy apart - what do I need to look for to determine what inside this darn machine has gone bad??? I'm a girl but I can do this just need a little help.

You probably can not make the determination of the cause for failure. Other hardware can casue the MB not to Post . Laptops are very tricky, even to open them up your can damage the plastic parts. Sometimes you can not even find the screws.

If you are going to scrap the laptop, you can take it apart carefully, saving the parts. If you Google long enough, you can find the Compaq Manual online.

Part it out and sell the pieces on eBay. There is probably someone who needs the screen. Take a look to see what they are getting on eBay for the screen, battery, charger, memory, harddrive etc. If you sell the HD you need to remove your personal data. Wipe the HD first. You will need a cable adapter to plug the smaller HD into a desktop computer but I do it all the time. You probably can not make the determination of the cause for failure.
