Apologies if there's already a thread like this. I searched but did not see one. Maybe I did not look hard enough.


Image

One of the most integral parts of a laptop: the power supply. It charges your battery and gives life to your computer. There are Good power supplies, the Genuine Lenovo parts that are weighty, diverse, and resilient. Then there are the Evil power supplies, Fake parts who pretend to be what they are not, luckily I don't have any. Then there are just the aftermarket ones that are blatantly aftermarket, they're not fooling anyone to their inferiority. Used Genuine 90W and 65W adapters are super cheap right now on Ebay, around $8 for a 65W and $10 for a 90W, give or take a few, make a best offer here or there. For most efficient results buy used Genuine.


Manufacturers of genuine Lenovo AC adapters include Chicony, Delta, Astec, Liteon, and Hipro, and some others. Differences between the manufacturers are minimal to none. The appearance of the AC adapters also changed over the years. The biggest difference can be found in the size, color, and position of the Lenovo badging, but it's not an identifier of who manufactured what, rather its a sign of when they were manufactured. You're better off just reading the date stamp on the bottom than thinking about the badges too much. A smaller difference is the plastic interface between the power brick and the tip-side of the cord - it can vary in size and shape even on the Genuines.

There are also two versions of the barrel tip models in which the shape of the barrel-extension differs. Older models have a smaller barrel-extension, while newer models have a longer and less-flexible barrel-extension to mitigate wear and damage to the cord. I've made repairs to two old-style adapters where the cords frayed out due to wear at the barrel-extension.

So if you bought old Thinkpads new, or collect used Thinkpads now, you can get a variety of different looking Genuine Lenovo AC adapters. According to Lenovo Parts Lookup, my 93P5026 with a 2007.03 date stamp, small badging, small cord interface, and old tip is a LiteOn. I also have a 2012 65W, and a 2010 90W with large badges and new tips. I believe the change to large badges and stronger tips occurred in 2010, with the introduction of the T400s.

Image
Left: Old barrel 90W
Right: New barrel 90W

I also had a new barrel 90W with a small badge. :??:

Most interesting is this 2006 "AC/DC" adapter with a Thinkpad logo: http://i.ebayimg.com/images/g/PEsAAOSw3v5Ym~8q/s-l1600.jpg If they had Thinkpad logos, could they ever have had IBM logos? :?:

There's also this 2008 T61 power brick with a printed logo: http://i.ebayimg.com/images/g/eRkAAOSwEzxYey4E/s-l1600.jpg My sister's T500 uses one of these.

Lastly, in 2013, with the **30 line, Lenovo made the 90W brick bigger and gave it rounded corners. Looks like this: http://i.ebayimg.com/images/g/jGMAAOSw9NxTvfkP/s-l1600.jpg I also have one like this.

I have also seen some rare IBM-badged Lenovo 90W AC adapters on Ebay and I was tempted to buy one for the sake of the IBM badge. I presume they must be, like the 2006 "AC/DC" adapter, from the Z60m era. Shame I didn't save a picture then. Lenovo Parts lookup gives me a generic picture when I put in my Z60m's SN. Or were they just well-crafted fakes? :BAAAD!:



Genuine v. Generic

Image

This benign Generic just says, "AC Adapter." At least it's not pretending to be Genuine. It says "Replacement" on the bottom. It has decent weight, but not as heavy as a real one. You can see the tip is shaped like the old style but is the wrong color: a sickly light gray. The cord is also shorter and the whole thing smells like death.


Image

The fastener is black on Generics (left) and stone gray on Genuine adapters (right). It also tends to fall off the Generic ones.


Image

Now here's a 65W Genuine next to the cheapest Generic 65W you can buy on Ebay. This Generic doesn't look at all like the real thing. It's incredibly lightweight, because it's brainless and gutless. It gets hot, its smelly, and the cords are super short. Don't buy it. It's physically larger than the genuine 65W https://s16.postimg.org/m4q6xkob9/DSCN4272.jpg and the tip is the wrong color.


Image

I wonder which ones are the genuine ones. Image

That's easy, I'd say from Left to Right: 1 (20V/65W), 4 and 5 (both 20V/90W) are real.
No. 3 looks to me like a Dell.

You're missing chargers from the 3-digits era, as well as 20V/135W and 20V/170W, not to mention the newer ones with flat DC-plug.

But a nice collection.

Surely only by opening them up will you know for sure if they are genuine or not?

That is one way. I know they're all good, the ones branded Lenovo.

I have an old IBM charger that I picked up from my work when they were disposing old Thinkpad stuff. I am overseas now so I can't post an image of the charger but it has little wings or ridges on the ends so you can coil the cord around those ends. I am sure you guys with older Thinkpads would have similar chargers.
The charger looks like something Richard Sapper would have designed. That functional IBM styling which we all appreciated.

Here are my adapters for the IBM ThinkPads: (my T530i is the only laptop that uses the newer connector)
https://1drv.ms/i/s!At7-rt1KJ7WviMtsVN9Y-0w1u-IF2Q
The one with the rubber band has its rubber protective shell (at the part where the converter connects to the DC cable) broken so with the rubber band, it prevents any further damage to that weak point
There is another one out of the four that came with either a T22, T23 or A30. It produces a weird high-pitched sound if plugged in to the wall and not taking the power on the other side (and stops once the DC connector is connected to a ThinkPad that is charging or powered on). So I usually don't leave it plugged in for very long.
I used to have another one that came with a 600, but now it stops producing enough power for a ThinkPad to work for some reason. (so you can assume it is broken?)

Interesting post, thank you. :)

A few things I know about fakes is that sometimes they will have slightly incorrect colors (like black Velcro instead of gray, or different shade of gray on the tip). Also their serial number is sometimes only 20 characters (should be 22).

The worst thing about the non-genuine adapters, is that they often fail to properly communicate their identity to the laptop. I've had one such adapter that was 65W but was presenting itself as 90W to the laptop. This is bad, because if the laptop thinks it deals with a 90W, and tries to pull more out of it than it can handle, all sorts of bad things can happen.

I think i have one. Plus i have more interesting power bricks to share this photo.

Image

Your is the 3nd in upper row. And yes it is the best design for cable winding. But i believe that this design was made long time after Richard Sapper made design for Thinkpad.

Some hints:
All bricks with black bands (except bigger one with Lenovo sign) are oldschool 16v powerbricks (before T60 era).
In lower row: two from the left are combo adapters (AC + car / plane charger) for new 20v and old 16v Thinkpads. After them 170W for W700 and the Bigger one is 230W for W701 (may be it is counterfeit but W701 think it is 230W and it is not hot when working).

In the upper row: Bigger one is the 170W from W530 with modded plug and X60 thinks that it only 120W ?? ;). After that one with yellow plug - 120W from the G41 and than 4 different 16v oldschool bricks (72W, 72W, 54W, 56W).

I mentioned Lenovo AC adapters with printed gray lettering, as opposed to colorless engraved. Here we can see two specimens of this style, a 65w and a 90w. The one on the left is a late 2006 model, probably shipped with intel T60, R60, Z61, and X60 laptops. I bought it on eBay and it looks in practically mint condition. I'm not sure about the 90w, it may have had a date sticker at one point that has fallen off. It gets warmer than my other adapters.

Here is the 65w to my second-hand X60s, which I can't remember if it's a 2006 or 2007 laptop. https://s15.postimg.org/g1x2qhy2j/x60s_65w_cropped.jpg

One extra adapter picked up today as local pickup eBay order alongside with a ThinkPad Mini Dock which is useful for my T4x machines to connect to my Samsung 1080p TV with no VGA connections supported. THIS, is the rare 4-pin high wattage adapter that comes with the IBM ThinkPad G series laptops.

Notice the size difference to a regular T4x adapter!

And the connector difference:

Well I have bought this adapter separately because the seller doesn't have the original adapter for the Mini Dock and surprisingly enough, the seller still has this G41 adapter which works just fine with the Mini Dock so why not buying them in the same place and pickup together like a bundle? :wink:
