computer crashing making a buzzing noise
my hp 6730 b laptop charger was beeping and eventually stopped working i replaced it with a loaner ..The loaner is a original hp charger but has less power volts are .5 off but the original had 90 watts the loaner has only 65 watts...it charges the bat to 100 percent..although i noticed the lightning bolt led is not staying blue like it was...it goes to amber at 60 percent charge and then blue like itshould somewere working up to full charge then it goes off..it used to stay blue.. i dont leave it plugged in at night..i figure i better not..NOW 3 DAYS LATER MY LAPTOP CRASHED TWICE AND BUZZED... NO SCREEN ...FAN GOING AND LEDS BLINKING...it would not shut down from power off on button....so i umplugged the charger and pulled the batt out...put batt back in and it said windows did nor shut down correctly..hit enter and it rebooted fine....how serious is underpowering a devise...in general i always thought under was ok within reason over was bad....??? im buying the original 90 watt hp block today.....cant risk it did i damage any thing...???
