Can I charge my laptop with a 60W adapter instead of a 90W adapter?!

Question

I have a laptop, and my adapter doesn't work. My laptop needs a 90W adapter. My friend has a 65W adapter of the same brand (it's a dell). Is it okay to charge your battery with another type of charger without turning the computer on?!

Thanks!

If the output voltage is the same and the connector is configured the samethen there should be no problem. I do it with my thinkpads and theirdifferent adapters all the time.

If the connector is exactly matched, and the voltage is exactly the same, it should work. Most likely the battery will take longer to charge.Do not run your computer with your friend's adaptor. Only charge the battery, if it is electrically compatible as mentioned above. Because its wattage rating is lower, the lifespan of the lower wattage adaptor will be reduced, or have a strong possibility of being damaged if you run a device that requires a higher wattage.-- JANA_____I have a laptop, and my adapter doesn't work.My laptop needs a 90W adapter.

So long as the voltage is within 10% or so and the polarity is the same, it should work fine. Do keep an eye on the temperature of the adapter to make sure it isn't getting too hot though.

My understanding is that it will work fine but the CPU will throttle back. My experience with a D800 was that even with the 90W adaptor it still throttled back. wrote:-- Joe Leikhim K4SAT"The RFI-EMI-GUY"©"Treason doth never prosper: what's the reason?For if it prosper, none dare call it treason.""Follow The Money"  ;-P
