this well help distinguish error beep codes

Dear Friend,
Normally all Lennox handler beeps right after turning on and off, but if beeps all the time it might be that there is an error with the handler or it beeps because it was program to beep when going on and off. Please refer to your user manual for any beeping error.

Good Luck!

Hearing a 'beep' is usually to warn you there is a fault. I do not know a single long beep as a code for your Notebook. Turn it on and do not touch anything, and see if there are any short beeps and/or other long beeps, and let us know
Quite often it is a fan problem, can you hear your fan running and does it sound normal?

Beeping sounds when you try to boot up? Is your system booting up all the way? Beep sounds help the technician isolate the problem with your computer booting. Beep sounds normally indicate a problem with the memory, cpu, keyboard, fan, motherboard, etc. The number of beeps can be looked up based on the motherboard brand or bios and it will tell what the problem is.

As for the alarm. I found no documentation that you can set an alarm on your car radio.

I had the same problem, beep beep beeeeep. Take all your music from mp3 player to a folder in your PC and transfer it back to mp3 and that should do it

there two kinds of beep a long beeping sound and a short with interval beeping sound, if you hear a long beeping sound, it means that you a bad or broken memory module, if the beeping sound is short and with interval the problem is the vga card, if you any of this two and you want to troubleshoot it but you are not certain on what to do have a comp tech check your system to avoid any more damage to your unit
