Re: W530 Power Adapters, 90W vs 135W Vs 170W

you can make the adapter by purchasing parts (DC Jack + 3 wire harness) and soldering middle pin to ground. as far as people making these wires, there arent really any who make them.

W530 with 90w and built cable

I built the adapter cable that grounds the center pin. 

 

At first it did not work, the green battery  would stay on when I powered thru the 90w and adapter cable.

So I looked at the center pin and thought it looked a bit short, so I tugged on it a bit with some pliers.

 

Now, I think it is working -- the battery light does not go on, but the battery icon reports "No battery is detected: with a red X thru the battery, but with the plug icon. Is this the correct behavior?

 

Also, I get a "Safe to remove hardware" (DVD device) message when I plug it in.

 

Appreciate any feedback.

Re: W530 with 90w and built cable

no. that is not the correct behavior. the laptop should not do anything odd like you described. you should open up power manager and see what it says under the battery tab. if it says 135w power adapter is attached all is ok. if it says your ac adapter does not provide sufficient power check woth a multimeter that ground is shorted to center properly. if it is, try another ac adapter. also make 100% sure that you are almost idle as your brick only prpvides 90w, which is enough for an idle laptop and charging battery but not a fully loaded laptop with charging battery.

battery light should go on and flash when its charging. when it isnt it should stay off.
battery should not display an x either. dvd does not eject for me eother. do you have power saving enabled for the dvd or something?

Re: W530 Power Adapters, 90W vs 135W Vs 170W

I just registered here to make this post.

First of all, THANK YOU! This made my W530 so much lighter!

 

When i found the information here i got really exited but lacked the connectors to make an external adapter. Therefore i looked for a more simple way of tricking the computer.

 

Here is what i did:

 

With this method i do exactly the same thing as dragon-fly, but instead of making a special adapter cable i do it inside the computer.

 

The operation is really simple and you only need to lift the keyboard to get access. The mod is as you will understand easely reversable and leaves no trace that it has been tampered with.

 

I used a small jump wire from a kit i had but anything will do. Just make sure it wont short against anything else!

I located where the middle pin of the power-plug is connected to the motherboard (blue cable) and used the jump wire to bridge it with one of the ground/negative ones (black).

This works good for me so far. The only problem i can see with this is if the computer now thinks that all adapters are 135W ones, even the 170W adapter. This is something i havent been able to check.
 dragon-fly, have you tested what hapens if you connect a 170W power source throuh your adapter?

 

Another really stupid thing is the 170W power adapter plug. Why did they change it so it wont fit other models? Since it's the W530 that is picky they should have made normal adapters not fit that model and not the other way around. I removed the extra plastic inside the plug of my 170W adapter with a small flat headed screwdriver. Now i have one big adapter that fits and have the power to run all Lenovo models and it works great.

Re: W530 Power Adapters, 90W vs 135W Vs 170W

no, I have not and can not connect my 170w through my adapter. it would stand to reason that it would work as a 135w adapter though. your approach is also good, but it does indeed force all adapters to be thought of as 135w adaters including a 170w brick. personally im not sure if there is any aituation where the 170w would make a difference over the 135w adapter. so there may be no ill effects.

Clever idea! 

Have you noticed any issues when you plug in your 135W adapter?

Re: W530 Power Adapters, 90W vs 135W Vs 170W

I don't have a 135W adapter here. So far i have only tested with 90W and 170W adapters whit out any problems so far. I have just used the computer casually, no stress testing or anything.

 

Went to the extreme and tested a 65W adapter too Smiley Surprised.

Worked during normal desktop with normal office usage. (word, excell Powerpoint and such) when not charging the battery. When surfing flash heavy websites the computer started to toggle betwen AC connected and not. I then tried to start a game (World of tanks) and that resulted in a BSOD that said the graphics card was unhappy. I am now running the game with a 90W adapter and no problems.

 

So far i am happy with the result. It got the job done and now works good with standard 90W adapters.

 

Just as expected does it recognize even my 170W adapter as a 135W one, but i dont know if that is a problem. If it is then maby i just do the same "hack" but with a 1,5kOhm resistor so it thinks all adapters are 170W.

Thaanks Smiley Happy
Doing it with a resistor brings another challenge since the resistance will be in parallel with the one in the power adapter making it more like 750Ohm but I guess the easiest way is to just test and se what happens. I will definitely post here letting you know if I start testing. Another solution is to have a smal switch that just disconnects the hack when you use a 170w adaptor.

And we're back...
