Try hitting F8 before windows attempts to load to enter the boot manager, from here you should select last known working configuration, if that fails, do the same except boot safe mode

Red switch on hp pavillion


Is it booting up to windows?

What happens when you press the Power Button?

Whenyou plug in the power cord is there any lights whatsoever on the laptop, wherethe plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the computer is trying to boot or may have booted,but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe you have a Static ChargeBuildup. Remove the Power Cord, then Press and Hold the power button for30 seconds. After 30 seconds plug the power cord back in and hit thepower button to see if it boots. Maybeyour memory is bad or the memory slot is bad.Removethe Power Cord, Open the Case and remove one of the memory chips. Set thechip aside then try rebooting the computer. If it boots, then you knowthe memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and tryrebooting. If it fails take the chip out and set it aside, then put theother chip in and try booting it in both slots. If it boots, just toverify that the chip set aside is bad, mark an x on it and put it into the openmemory chip slot and try booting.

Laptop Touchpad - cursor random dragging problem


On my acer all I have to do is press function F7, Function is the button with 'Fn' on it. I am not sure if that works for HP, but its worth a try. Also, is there a switch near the touchpad? Sometimes there is one that switches the touch pad on and off. You can also try other Fn(function) F1 or Fn F2 etc. and see if one of the other "f" buttons work.  I hope this helps, let me know how you made out. Good Luck!

Hp pavillion power problem


Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:
CAUTION: This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.
1. Disconnect all cables from the computer, including the power cord.
2. With the power cord disconnected , press the power button on the front of the computer for five seconds.
Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply.
3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America.
Performing this step ensures that the voltage switch is engaged and set correctly for your country/region.
4. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet and test to see if the computer can turn on.

I have a hp pavillion 710 pc when it is plugged into the mains supply the power light comes on for a second and then dies out,would this be the power unit which I plug into


I think I had this same problem once before. It sounds familiar but could use a few more details as to exactly what happens. From what you have said so far though it sounds like either the main power to the PC is switched off, or your power supply for the machine might be bad. First I would try looking in the back of the computer. On some of them there is a little switch usually towards the top that allows you to turn the computers power on and off. If you plug into the wall it usually will come on for a second before turning off and then when you go to turn you computer on if the switch in the back is off you computer will not start if you use the normal power button in the front. I hope that fixes your problem. If that is not the case please give me a few more details on it and I will do my best to help you get to the bottom of it :). Good luck.
