The charger charges my battery an you can here the laptop come on an the fans come on, but when I press the power button the white light on the front end comes on goes off then continues to beep in 5 second intervals until I turn it off. I tried using force restart the light just flutters comes on then continues the beeping noise. I looked on apple support forums an looked up what the beeping codes were an it says no ram install so I check that there's a 2 gig an 1 gig ram chips installed. I pulled one out an left the 2gig in an powered on display still is off an the beeping continues as usual. What is going on? Us these repairable? Cause I run a home studio gfx editing video an vocal recording an I need my laptop working again.
