My laptop charger is beepign and wont charge my machine....?

It maybe possible that your charger has outlived its productive life. You may need to buy a new one.

If you have Volt metre than you can probably test the Output Emf at the wrap up of the Power Adapter ( the end that connects to the Laptop). Provided the Power is up to the output shown on the Adpater then it is probably O.K. maybe something other went faulty. Also Try-out your battery, it is possible that the issue maybe with the battery.

You could do all the above if you take the Laptop Battery and the Power Adapter to the nearest Computer Store. Near the Upgrade Center could probably help you.
