My laptop is stuck on a spinning loading screen. The model is a HP Probook 455 G3 and the laptop has passed an extensive system test.

SOURCE: On boot up screen reads "Loading PBR 2...done"

As the notebook is starting you see the Dell 'Splash' screen. Press F2 to go into the BIOS setup. Check to make sure two things: first that your cd/dvd and hard drive are being recognized and identified, second that your boot order has the cd/dvd first and internal hard drive second. Your machine may be trying to do a USB device boot or network boot when these options are not available. Next try pressing F8 immediately after the splash screen disappears to try to get into Safe Mode. If it still fails to boot, I would try booting using a Windows XP installation disk and then going into the repair console to check if the hard drive is damaged or corrupted.

F12 to get boot menu then select CD. The CD drive should led up. If it doesn't read the CD clean the CD in straight motion, try another boot CD as well. If it won't read at all, then your CD drive may be defective and need replacement.

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.

Locate your Fn key, and look for the speaker icon, mine is on the Ese button, yours maybe on one of the F buttons at top, once found. Press Fn key and hold now press the F key that is the speaker icon, sound shuld be restored.
