You have a bad motherboard. fans are hi all the time and power lights are not functioning correctly indicates a bad circuit on the board. Fortunately, a motherboard is not a terrible expense and it would fix all your issues. Here is one on ebay for 60.00 with shipping. http://www.ebay.com/itm/like/390983723021?lpid=82

HI There

Sometimesa power supply will start up giving 12V and 5V, but this drops to below what the computer can handle, and the computer therefor switches off. try another power supply (borrow from someone if you do not have a spare) and it should be at least 250W. If this sort your problem out, its the solution.

UIt could, however also be a main board problem, which is more expansive to replace.

Regards

Andre

Pull the power cord out and press the power button on the PC to drain the power for 10 seconds. Then plug the power cord back in and turn the computer on. If still does not work, then the power supply may be blown out and needs replacement.

Hello

Do a hard reset on the laptop by removing all cords and connections from the computer, including the power cord. Turn the computer over and slide the tab next to the battery, then lift the battery out of its compartment.

Eject any SD cards currently inserted in the SD card slot by pressing on them, then remove them from the slot completely. Hold the computer's "Power" button down for at least 15 seconds, then plug the power cord into the computer and turn it on.

Watch to see if the LED lights near the "Caps Lock" and "Num Lock" illuminate. If the lights do not turn on and the computer's screen remains blank, inspect the power cord and AC adapter for damage and replace them if necessary.

Leave the power cord plugged into the computer and snap the battery back into its slot. Allow the computer to sit for at least 30 minutes, then unplug the power cord and press the "Power" button again to see if the computer will turn on.

Plug the power cord back into the computer and try to turn it on again. If the computer turns on, replace the battery with a new one. If the computer still does not turn on, take the computer to a repair shop.

I press the power button at the front of the tower and it doesn't activate the PC power.


The most common reasons for this are: 1. Switch failure (the button is broken) 2. Power Supply not working
If you can go inside the case of your PC (if confident that you won't mess up with any other thing).
First of all remove all power cords (even the monitor's wire) open up your case again if confident but its better if you get it checked by a technician. By the way to check the switch the method is given below (i expect that you have a reset button)
There must be a wire on which PWR would be written it will be directly connected to the mother board. To get to it look for the button inside the case and follow the wire, when you find the wire carefully take it out and carefully search for the wire of the reset button and connect the reset wire in the place where the power wire was connected.
Plug in all the wires back again cautiously and then press the reset button and check whether now it turns on or not.
If the above method works it means you have a faulty power button and if not then you have either a power supply problem or In some extreme cases the mother board can be burnt.

Cant open the case to my HP pavilion 700


First, turn off the PC, remove the power cord from the back of the PC to remove the 115 volts then push the power button for a second or two so the capacitors will discharge. This is important because the residual charge can cause Motherboard damage especially when changing the RAM. You should follow this process ANYTIME you enter the PC case to make changes, etc.

To remove the side panel on a Pavilion 700x series:
Only one side panel allows access to the inside of the Pavilion case, the left side if looking from the front of the PC. The left side panel has knurled thumbscrews, not machine screws. Loosen the thumbscrews, they are designed to stay attached to the side panel, place your hand on the middle of the side panel and with inward force push the panel towards the back. The panel will slide and inch or two and you can pull it free. This proccess is easier if the PC is unplugged (push the power button on the front of the PC after pulling the power cord to dischard the capacitors) and the right side of the PC laying on the floor. This allows easy access to the left panel and allows light to enter the case from above to change/add the RAM you want to install.
