AC adapter compatibility with laptop

Ibm Ibm thinkpad 600e ac adapter

Specs: Linux i686, 1.6gb/2gb
Hi i have a IBM thinkpad 600E without an ac adapter and happened to have an adapter that i thought might go with it. Did a google search and the one i am supposed to have is http://www.upgrademaster.com/device...

but i have this one http://www.pchub.com/uph/laptop/46-... which is model number 02K7012 which has lower specs that for the laptop i have. When i first plugged it into the laptop the light went on and then i am not sure if i pulled it out or turned it off at the power point. I have no idea(can't remember) and now the light doesn't go on and no charge takes place. Am i supposed to get something from this adapter? Ultimately i don't know if the laptop is working and i don't like to spend money on parts for nothing.
I just happen to have an adapter in my box of cables so i thought it might help my situation?
Can anyone advise me on this as i am just an ameteur

You can't tell if your adapter is working without testing it. It is underpowered for the Thinkpad and may have been damaged. Or it may have damaged your Thinkpad.

I am not sure but I don't think the smaller amperage would damage anything. Could be wrong.

What might damage something though is reverse polarity. I have read from others here that some brands use negative on the outer contact and some the opposite. If you ran into that, then you probably damaged the laptop.

IMO, this practice is unconscionable. The only possible reason to make a charger with the opposite polarity would be to create proprietary hardware, which forces folks to buy from you. The outer contact should always be negative.

The original was rated at 3.7 Amps. The new one, 2.2 Amps. Less than two thirds of the original. This means the the power supply was being overloaded and has almost certainly destroyed itself as it tried to keep up with the demand that was being put on it or, if you are lucky, it blew a fuse.

You can never have too many Amps, but too few will cause overheating and eventual failure.

Oh ok oh thanks for the advice everyone. It is something that was being thrown away and i am always saying to people don't do that. I am always saving old stuff he he. I am always learning new things so will go in and see what parts might be usable for some other old notebooks i have. I give them to people who can't afford a computer or a friend that is sending some to his country to poor kids. I don't want to send this as it is better to know 100% for sure it works :0)

Read the labels. Get a good voltmeter.

Sorry the labels on the base of the notebook? I am running on no money so maybe one day i will get one of those but in the meantime i don't know how to use them anyway. On a pension and things are not going to change anytime soon. Thanks :0)

When salvaging computing equipment, the equipment tags give important information about the contents. A multimeter can be obtained for less than $20. I've found them for under $7 on sale.

OK sorry unfamiliar with the terms. So the stickers on the base of the laptop is what your saying? What information is it that i am looking for? And for what? Do you mean to know which ac adapter to use? If not what else? Anyway i know which so i am unsure what your point is.
OK i would still have to know what to do with the meter and when i mean broke i mean food comes first and nothing else yet. Anyway when money becomes available i will look into whatever it is and follow up.

Stickers give all kinds of information The manufacturer, model numbers, serial numbers, power ratings, etc. Using google you can get additional information, user manuals, and parts lists.

All Power supplies have a label on them that give the input Voltage and amps as well as the output voltage and Amps.

The Input will be 110/230 Volts 60/50 Hz AC.

The Output will be 14 V 3.5 Amps for example.

You need to match the output with the input requirements of the device you are connecting to.

Volts should be as close to the input as possible. A little under is acceptable but never over.

Amps should be the same or more but never less.

If the device consuming the power is demanding more than the power supply is capable of supplying then there will too many Amps flowing in the circuit and things started getting over heated and burn out.

Volts and Amps are closely related along with resistance. To understand this relationship between Amps (I), Volts (V), Resistance (R) and Power (W) you need to study Ohm's Law. It is not complicated and bring it all into perspective.
