Hi mt,
Could you please share the exact system model no. of the computer. Inspiron 15 is available in different variants. Also, share the number of beeps you hear from the computer. Please check for any stuck keys on the keyboard.
When exactly do you hear the beeps?
I would also suggest you to run the Dell Diagnostics to check the hardware functionality. Power off the computer -> restart the computer, press 'F12' key on the Dell logo -> Select 'Diagnostics' from the boot menu.
Thanks and Regards,
Appu S
Hi,
This has been going on for a while now, don't remember how long, computer gives an error beep consistently, & often I get an error message that an unidentified usb object is plugged in. Sometimes nothing is plugged in at all & it still beeps, so much so that I mute the sound.
How can I stop this? Running win 7 on a dell inspiron 15, purchased a few yrs ago brand new. Haven't really added any thing new for some time.
Thanks so much for your help.
