My Inspiron 15 3000 Series laptop makes a continuous beeping noise where is beeps 5 times, then pauses, then repeats everytime that I try to start it up. What is this? Can it be fixed? This laptop is only like 2 years old.
Could be a weak or dead reserve battery (usually a CR-2032 lithium button cell on the mainboard; about $1 or less on Amazon). Replace that first.
If that doesn't solve the issue, it's a bad clock chip -- that can't be replaced; if the clock chip is bad, you'll need a new system board.
If you need details, post the model number (i.e., Inspiron 3521, 3558, etc.).
