When buying an Compaq Presario F700 AC adapter, it is always better to buy a new and original adapter for your laptop or notebook computer. But, just in case, you are planning to save some money and going for after market AC adapters, you should always check out a few things.

· The notebook’s power jack should not wiggle, making the laptop power off unexpectedly.

· You should not get a universal AC power adapter.

· You should not buy an OEM or an OEM-compatible laptop AC power adapter.

· You should always buy an adapter with the proper wattage. That is, a wattage corresponding to your laptop.

· Make sure that the adapter’s tip is of the correct size.

Correct Wattage

Your AC adapter ought to be within 1 amp or 1 volt of what is written on the base of your laptop. Any more current or wattage than that can in fact cause damage. What does this mean?

On the base of your notebook there should be a label or a sticker that says what kind of ac power adapter it works with. For instance on a Compaq Presario F700 there will be a sticker that says: Compaq Presario F700 with 3 Pin Power Cord(18.5V, 3.5A, 65W).

Even while the label says that it can allow a Compaq Presario of 65 watts, which means 18.5V and 3.5A or  65 watts, which means 19V and 2.4A, 2.7A, 3.5A, the perfect adapter would be the 3.5A.

As a general rule, you must not use an AC adapter that offers more than 1.5A or 1.5V of your notebook’s specifications. Doing this can in fact cause damage to your notebook’s motherboard with time.

It is not exactly unsafe to buy a generic after market AC adapter, but it can definitely give some problems during the use. Some troubleshooting tips for those cases are:

You pressed the power button on your notebook, but nothing happened, no power, no lights, no anything. It could be the generic ac power adapter, but not always. Here are some easy steps to save time and aggravation before buying a generic ac power adapter for Compaq Presario F700 notebook.

* Check the notebook’s battery charging icon. If the notebook is getting power, but not getting switched on, then the power adapter is not at fault.

* Look for the light on your notebook’s ac power adapter. Most ac power adapters have small light or lights to indicate it is running properly.

* Make sure that the power cable is fully plugged into the socket and the ac power adapter.

* Verify the working of the power outlet with some other electrical appliance.

* Try taking out and re-inserting the notebook’s battery.

* Wiggle the notebook’s ac power cord connector at the back of the notebook to see if it starts getting power.

If none of this works and there is no light on your notebook’s ac power adapter, you should test the notebook with a known working ac power adapter.
