there is a way to reset the printer to factory settings, I had to do it a few times when I had this printer. Call HP and ask them for the reset sequence.

Dead battery? Get a jump! haha Seriously now.Are you sure its the battery? Does it work when its plugged in? As soon as you unplug,does it stop working? If that's the case,I'd take it in to a computer shop to get looked at.Is it still under warranty,& if that's the case,send it in.I haven't looked at my own manual,but can you change the battery yourself? I'd see if I could do it first myself,instead of paying omeone for something you might be able to do yourself.

I have the same problem. The light in front is on and the power button is pushed one way and it still dose not work. I have the same problem and mine has been on charge for several day's and it still does not work, and the button is in the right place.

If you haven't figured this out by now, use your on screen manual that should have loaded to your computer program list when you loaded your printer. I've not had this problem, but did have one and after hours of researching on Google I brought up the manual and followed the directions - viola, problem solved. I did have a paper jam once and couldn't see it until I opened the back of the printer. Also, always remember to push the flashing button when you've completed any task - it let's the printer know to proceed. (Richard's wife, deb)

Mine never worked at all. My advice would be to do like I did: request a refund, then throw this battery in the garbage and spend a few bucks on an Anker or other decent brand. :-) Seriously, you may want to remove the battery while the computer is plugged in and see if it changes anything on the status display. If it changes, you know the battery is bad, if not, I would suspect a problem with the computer.

I had an issue where the power button needed to be pressed repeatedly in order to start it. This kind of an issue is being reported all over message boards. I did an exchange on mine to see if that would help.

I just read this post from the product review section on amazon from "Traveler". Hope this section of his review helps with your problem as well. DJ UPDATE JANUARY 23, 2012: After over 5 hours with the HP Help Center, not arriving at a solution to the printing errors and scanning problems, I was ready to return the printer to HP. However, I persevered. The printing was perfect as long as I did not let the error messages bother me. The scanner was not functional. Then a few days ago, I came up with an idea. IPv6 has been in the news lately due to the lack of internet addresses under IPv4. I wondered if my laptop and desktop were using the same IP versions. Sue enough, the laptop that did not have problems was using IPv4 and the desktop had IPv4 and IPv6 activated. So, I disabled IPv6. Ever since, the printing errors have disappeared and the scanning functions perfectly! YEAH! I am not ready to declare 'VICTORY' yet, but after a few days, everything is still good. So, I will raise the product rating from 3 to 4. Too bad that the HP Help Center and their diagnostic software could not have saved me so many hours of frustration.

Check your control panel to see if it's still recognized. I've noticed that it always needs to be reawakened by pressing the trigger before anything else will work, but I'm sure you've tried that. The best way to know if it's alive is by seeing if it will work with any other computers. Of course, it also has a rechargeable battery.

Sorry, can not help on this. My unit was defected and I return it back to factory, never work. I got HP after and happy with. I'm answering because Amazon ask me to do this.

this has a unique HP power supply, so if you're saying the power supply itself is bad (AC adapter), or the cord that goes from the power supply to the computer, you must get an HP replacement. I don't know of any after market replacements. Go to the HP website to make sure it's not your battery (can't tell from your question), which will help diagnose the problem with the power supply or the battery. The site also explains how to get replacements depending on what country you live in. Sorry, not enough info to help, but the HP website can get you better info to make sure you're addressing the right problem

Try this not sure if it will work for you but it did for me. The moment you press the power button and release it and hit the floor button which hopefully will have taken you to the boot menu select the first choice given and enter and it should allow you to login to your desktop. As this happened to me recently. If this does not work. I would suggest taking it in for repair. Also if your desktop is still under warranty I would see if they can help you on HP.

To my knowledge, you can't power it on. I just put mine to sleep and then use the keyboard to bring it back up. But if you have shut if off, you'll have to open it up to power it on.

I know it is hind sight but you had a year warranty on the laptop. Since you have opened the machine that could be waived, now. I sounds like a power or motherboard issue. Definitely go to www.HP.com/support and get the HP tech support phone number. You might try 1-800-474-6836

For me, I ain't have any power on/off issues on mine.You need to check if it has been misused unknowingly.Mine still remain ok.I have two of it, they are very ok

Check the new toner make sure it's installed correctly and full. I always put a piece of black tape over the sensor so I don't get that warning when it's still half full. Then I would turn the power off, unplug it for a minute or 2. Then plug it in and follow the reset instructions for that printer. They're available on line.

Glad you got it fixed, but that didn't work for me. Pushing down hard (and holding down) the power button turns it off momentarily so perhaps the defect is in that area and you were able to fix yours by applying pressure while turning on/off the wireless. Would be interested to know if it works for anyone else. I've just gotten used to it being on at this point.
