Usually a rapid blinking charge light is alerting you of a battery fault. Try taking the battery out, plugging your computer in, and turning it on (with the battery out). If it boots up, then your battery is to blame, call customer service right away and see about getting a new battery.

The quick specs from HP does not show a volume control. Most laptops are designed this way. All volume controls will be located on screen unless you have touch lights across the top of the keyboard, which in that case there would be 3 speaker icons (one is mute, and the others are volume Up/Down).

pls. check the internal speaker audio cable is ok or not. and also check the audio cable is connected on the audio section of motherboard.

Computer does not boot up The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact. Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you. Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.
