You might want to check on [http://www.nullamatix.com/dell-diagnostic-beep-code-troublshooting-chart/|HERE] for the beep codes of your dell. I would remove the AC power, remove the Battery and also the RAM. Then try to reinstall it with only on memory module at a time. Also try one module in the different slots and see f it makes a difference. If your computer beeps 7 times, it is possible that it is actually a 3-3-1 beep which points toward the memory. Good Luck and let us know so we can all learn.
