If the data in description of this universal charger is similar to the data on original charger of the laptop then all should be ok.

You are going to be OK using... I think you are referring to the non-grounded plug on this power supply.

The reality is your more likely to blow out the power supply than the motherboard, from a surge. And motherboards can have a fuse on-board to prevent a catastrophic result.  These fuses can be difficult to replace (soldered on the board) and hard to debug without a meter.

The AC plug can be two-prong and either it plugs in to an outlet or you need an adapter. Most all AC adapters cover from 90 volts to 240 volts (universal).

The DC plug need to fit exactly into your device. No modification.

The power rating and voltage of the adapter needs to match you device. Normally the DC Plug makes sure that strange adapters cannot plug in.

Within those constraints, you are not likely to have an issue. If you have flaky AC power, get an external surge protector.

The 2 prong just means you don't have an additional grounding path.  That ground path is not absolutely necessary for equipment that are well insulated.  The 3rd prong ground path is used in devices to prevent shock to humans in the event that some wiring came loose if you have a metal case.  If you have a device that has a metal case, that you can put your hand on, then the extra grounding pin is absolutely necessary to prevent current from flowing through you when you touch the metal case if some wiring came loose and touched the case.

Here's an additional reference.
The idea behind grounding is to protect the people who use metal-encased appliances from electric shock. The casing is connected directly to the ground prong.
should work - if you have the correct DC connector tip for your laptop

All experts state laptop charger is safe to use.

I have a related question where computer crashes until I unplug charger.
Once I unplug charger, then computer works.

Since getting universal charger I now need to do this once an hour.
With manufactures charger, much less.

Thanks for the update. Manufacturer product is always engineered to work efficiently with the particular device. Manufacturers often have more than one AC charger as a result.
