Re: one long beep and 2 short beeps
Depending upon your BIOS manufacturer, generally this POST error code means either a video card problem or a motherboard problem.
If the RAM is OK then you have a motherboard problem, and this may not be cost effective to fix. Consider putting your money towards a new laptop, remove the hard disk and put it into an external USB adapter case and use it as an USB hard drive for backup etc.

The beep codes indicate you probably have a dry joint on your GPU. A reflow should fix it. if you don't know what a reflow is, it's probably not in your skill set, here is a page with a video to show you how it's done. good luck.
1 long beep followed by two short beeps is usually indicative of a failed/failing display adapter. On something as.... rustic as your dv2000 it can be fixed.... but probably would see better value from just replacing the unit.
The 1 long 2 short beep code means a problem in the video circuitry and the laptop can't initialize the display. This is usually caused by failure of the integrated video chipset. Unfortunately, on a laptop you can't just open the case and install a new video card like you can on a desktop. You need to replace the mainboard. Replacements are available online. Here is one source found by a Google search. (I'm just using this as an example. I haven't dealt with this site.)
The 4 beep code means no memory detected when the computer started up. No surprise there since you had taken it out.
Hi... I had the same problem... The solution is only temporary and you will have to reapply it after around 5 to 6 boots cuz it'll just happen again (the beep syndrome).
Just heat up the laptop by turning it on and covering its air vents with your hands.
Then after you hear the beeps turn it off. Turn the laptop on again and immediately turn it over upside down with the lid closed ofcoarse (simply put it on its back).Hopefully you wont hear the beeps and when you open up the laptop lcd...voila display.
