weirdest thing ever, my laptop's power supply is beeping at me

when my brother first told me the laptop power supply was beeping, i smacked him and said that it doesn't have a speaker. then that night, i heard it myself. it's beeping at 1 second intervals. the real problem is though, is that it's not charging the battery. i now have a useless laptop. i forget the model, but it's a Compaq produced last year. It's a model with a 1.2ghz celeron if that helps any. Normally I'd just think the power supply is dead, but what does the beeping mean?

I have heard 5 laptop HDD's make the bomb dropping noise (high pitch that changes to a low pitch). That always turns a few heads.

Regarding the noise from the adpt, well I have had heard capacitors make a high pitch noise. It is possible that a capacitor makes the noise as it charges up, discharges, and then makes the noise again as it charges back up. Of course, what do I know, I am not an EE or electronics technician.
 
No, the laptop would not power on after I used all the battery's juice. And yes, I mean the external AC adapter.
 
I think when the power jack shorts the juice it blinks.

If you put 2 wires from the power source together it would do that too.

Did you check to see the output on the laptop matches the ac adapter

I have lots of different compact adapters with different setting

usually its
19v 3.16A
but it can be
18.5v 2.8A or similar

maybe it don't charge cause the amps are wrong
suggestion check the back of the laptop and see the settings
and also read the settings on the adapter
 
INPUT: 100-240V~ 1.5A 50-60HZ
OUTPUT: 18.5V 4.9A

This is the ps that came with the laptop, it has been working for the past few months. I'm going on eBay now to look for a replacement.
