Hi,

you need to remove the battery and after minute or so you can put it back...

the theory is that by that time the BIOS gets reset....
so that it will load with default settings....

if that one didn't work then do it again then,
remove the RAM from the board rub it with a soft cloth do not touch the pins with bare hand..

it should solve it

Hi,

a common way to solve this is to put the BIOS into its defaults...
i.e, loading the BIOS with default settings..

to do this you need to open the case of your CPU then, on the motherboard there is a small battery called CMOS battery...
take it out and after a minute or so put it back...

in this one minute, the BIOS will get reset to its default settings...

you should now be able to work........

If this sol. helps please give a vote....

In case somebody has the same problem. Result of my investigation: * If everything is ok then the Presario CQ61 boots without battery. * HP support recommends to do a hard reset i.e. remove power supply, remove battery, press power button to discharge everything internally, connect power, press power button In my case the problem was solved by changing the AC Adapter (Power supply). Note: The led besides the power connector is not reliable. It is on with the working and faulty adapter. Note: The voltage level at the battery pins is not reliable. I had same values.

old PC,, Cq series. cq62-nnnnn you left off the nnnnnn cq62-100, 200 ,300 what? running mS windows 8 HP does not support W8 on this PC so that means you are on your own steam...

Oh dear you have broken this and will need to send it off to be fixed.

Won't load in safe mode?? What's your operating system? Has the hard drive been formatted?

1. Turn off your computer. 2. Press the power button to turn your computer on. 3. Hit F11 a few times quickly, while the launch screen is still up. This will launch the Recovery Manager. (If you see the Windows 7 boot logo, you've missed your chance and need to restart your computer and try again from step 2.) 4. On the left side it will say "I need help immediately". Underneath that there will be an option that says "System Recovery". Click on that. 5. There will be an option to either back up your files before restoring, or to recover without backing up your files. In my case, I'm recovering without backing up my files. 6. It will tell you to make sure all devices are disconnected from your computer. Make sure they are, and then click "OK". 7. There will be a "Welcome to the Recovery Manager" screen. Click "Next". 8. It will begin to reformat your partition and to reinstall the Windows 7 setup files. Once it's done doing that, click "Next". You'll be brought to a page saying "Recovery is Complete". After that all you need to do is reboot, and it will bring you through the wizard to set up Windows 7, just like on a new computer! Good luck :)

THIS IS NOT A PROBLEM THAT NEEDS to be asked on here as there are so many stolen laptops about ,ull need to go to a repair shop with proof of purchase or something that is on your system that only yourself could identify , to regain access to your laptop..

Try to reinstall windows formatting your Hard Drive... It seems to be an windows crash, or some software.
