T430 with X200 Charger

2021-10-11, 16:26 PM

The amperage readings are different but at a pinch for my next religious Zoom cast, can I get away with it?

 


My dog chewed my bros charger while he is staying with us, negotiating a marriage bust up!

The amperage readings are different

 

You can use a charger with a higher amperage rating with a system whose charger has a lower amperage rating, but not vice versa or at least it's not guaranteed to work.

 

For example if your T430 came with a 90W (20VDC x 4.5A) charger and the X200 came with a 65W (20VDC x 3.25A) charger then you can use the T430 charger with the X200. The X200 charger may work with the T430 however it may not be powerful enough to both run the T430 AND recharge its battery.

 

There is no harm in trying providing the voltages (20VDC) and connectors are the same.

Thanks for your explanation. The lower amperage of 3.5 compared to 4.25 may not be beefy enough but hopefully will charge whilst in sleep mode.

Underpowering hardware can damage it.

 

Running a model that requires a 90W charger with one that produces only 65W most likely means either that the battery will recharge very slowly or even that it won't recharge at all. After all the system still receives full power from the battery.

 

Running a system without any battery using a charger that is insufficient to power it may cause problems, especially if usage maximizes power consumption, e.g. playing a demanding game with screen at full brightness, etc.

If the T430 has integrated graphics, the 65w charger will always be sufficient.  If the T430 has NVIDIA graphics, it might need more, depending on what you're doing.  If it needs more, it will also use the battery.
