Question about Computers & Internet
4 beeps is a graphics controller failure. Try a hard reset. Unplug all peripherals (USB, monitors, etc). Then unplug the charger and remove the battery. Press and hold the power button for at least 15 seconds. Reconnect the AC power (but do not insert the battery) and press the power button. Check if the glowing LEDs (near the Caps Lock and Num Lock lights) appears and listen for sounds of hard drive activity and the fan turning on.
Next listen for the beep code again. (For example 3 beeps is a bad memory module. Sometimes, removing all the memory and reseating them one at a time will solve this. You add one module, reboot then try the other stick after removing the first if the beep code repeats.)
Since the laptop has the NVIDIA GeForce 8200M onboard video controller, if the 4 beeps error continues, you probably need to replace the motherboard.
For more beep codes, see http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01732674&tmp_task=solveCategory&lc=en&dlc=en&cc=us&product=3827788#N215 .
I hope this helps.
