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

Hi,

 

and i still have problems with my 90W power supply from lenovo. Sometimes it works fine, but sometimes screen is flickering and system becomes unstable, sometimes even ends up with a blue screen. It looks like  power supply was plugged and unplugged very fast, several times per second.

I have checked cables and plugs very carefully, it doesnt matter if power supply is warm or cold, no rule. Any ideas what can be causing this problem? Maybe power supply itselfe is buggy and i schould get new one?

 

p.s.

Happy to hear that this plug hack is working to so many people.

this isnt really an official mod, nor is it supported or recomended by lenovo. heck, they do everything to try to stop the 90W from working on this machine, so problems can happen.

 

i would try with another power adapter for the time being, another 90W adapter. then, maybe a shorter cable.

Hi dragon-fly,

 

I've been reading through all the posts, thanks for all your information and advice! Are you interested in selling any of your custom cables (I know you don't have them just laying around, but my intention is to pay you for the creation of one - depending upon the price)?

 

No worries if not, but it would save me the extra step of finding someone around here to make the 90w adapter work for our W530.

 

Thanks again!

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 made one with a regular twisty tie cut to about 1/2" and stripped the plastic off at both ends then just plugged it right in.  Worked perfectly.  The only problem I'm having is getting a 4338 docking station hacked to also think its 135W.  Looks like one of the pins on the dock needs to be shorted to spoof it as well since the bridge jumper method only works when plugged directly into the notebook.

thats correct, you'd have to disassemble the dock to find it, or maybe even two docks if yours is completely open circuit

 

*EDIT* See comment 2 posts below - may be incorrect

I just made the adapter cable and I'm using it with a 65W power supply and not having any problems, It  works fine on the planes and even in the office. I have been watching the power and never get's much above 50W during operation,

I disagree with one thing stated above. I put a w530 into a 90w 4337 dock and plugged in a fake 170W adapter. (90-watt with center pin connected to ground through a 1.5k ohm resistor) and it worked without issue.

i believe he would want to have the mod applied directly to the dock without the assistance of the power adapter, but i guess using the adapter method would work as well.
