Question about Dell - PS-5201-7D (PS52017D) Power Supply
I have got three dell laptops and three other brands of laptops. we teach dancing and use the laptops for music through our sound system. The three other brands i have no trouble with, but all three dells hum when on the power adaptors. Using the batteries no trouble. Is there anything i can do like using another brand other than dell power adaptor, or is there some other way of stopping the hum. STEVE
as i understand you are facing this hum on all the three AC adapters,
there could be any of the following reasons for that
1) If the laptops were bought within the same period and all the AC adapters came from the same faulty lot
2) Or the AC adapters are made in this way so they produce this hum always
Try calling their Tech support helpline for Dell and see if a replacement can help you or if the AC adapters have a design fault of producing hum is their a solution that they have for it
If you Think my solution was of any help please do rate me
