usually the problem is with power adapter .

See my post.

time to get a new one

Remove the Power Cord, Remove the Battery, then close the lid and turn the laptop over and remove the one screw that holds the dvd drive in place on the bottom of the laptop. Remove the Dvd Drive and in about 20 seconds put it back in and Try rebooting to see if it solves the problem.

Your dvd drive might be defective and needs to be replaced. You can find one on ebay. Just put HP Probook 4510s DvD drive in the search.

Once you take the dvd drive out you can also search on the model of the dvd drive. The model will be listed on the dvd drive.

IF you set the BIOS password then when you power on the notebook it you would be ask you every tiem BIOS password and not if you want to remove bios password then go in BIOS utility then remove bios password

That is the link to the service manual for the Probook 4510s. I believe what you're looking for starts on page 64. HP and Dell are both pretty good about putting the service manuals online for anyone to use for reference. For more manuals about the Probook 4510s check out

Typically there are two ways: through the keyboard, usually a function button and brighter or darker button, and 2nd in the power settings. Lower screen brightness gives much longer battery life.

Hmmmm, what do you mean by the master reset button and what do you intend to accomplish by pushing such a button. If you're wanting to "reset" your operating system, then you will need to use your recovery partition if you have one, or the recovery discs if they came with your laptop. To my knowledge there isn't a master reset button on your laptop; other than the power button.

Your battery is shot.
