I have a 6-month old w510 laptop and since recently major stability issues. These issues occured since i began using wifi more often and a 90w power adapter instead of the recommended 135w brick.
When first some performance issues (read system almost hangs) occured my first thought was that it might be related to the power adapter , so i played with running just with battery and that seems to perform a bit better. Lenovo support tells me thought that the only affect a 90w power adapter should have is that the battery charges slower...
Then the screen froze several times over several days. Laptop was completely unresponsive to any userinteraction. I had to reboot forcefully. I read up on this in the forums that it seems to be a problem also other users have.
So I contacted Lenovo support and they got me to execute a PCDoctor Full test from CD. I did that and all tests executed successfully.
After that Lenovo support tells me: Then it must be the OS / Software and that I should reinstall the OS. This is obviously a major issue with all the programs and customization I did.
So my quesitons apart from how to possibly solve this (I tried downloading the all newest drivers from the thinkvintage tools, especially WIFI and Nivida: until now no freezes anymore, but Performance still slow, especially startup.):
My Laptop was running fine with the factory settings. Problems occured after installing software and all. So I just do not want to go over the major setback of reinstalling everything juts to find me in the same situation 1 month from now, and then eventually have to send in the laptop.
Thanks for any help

The fact is that the 880m is a 135w video card.
I think you accidentally added a 1 to the max power spec, Don820. From:
Quadro FX 880M Specifications:
...Maximum Power Consumption: Up to 35W
Although the max power budget for the processors alone is 90 watts for the W510 (with i7-920XM CPU + Quadro FX 880M GPU). Note that the machine can and will draw power from the battery, if needed, while plugged into AC power.

It's not the GPU that takes 135W.
It's due to the whole cirtuitary in the W510.
having 135W activates the intel turboboost, without 135W it just runs normal without it.
So a 90W works fine

I have 3 90w adapters. None of them "work fine". They all cause my system to run unacceptably slow. Not sure what your configuration is, but on my system the 90w adapter is for absolute emergencies only.

Are you serious?
I have 2 90W adapters and all of them works well.
Compare using a 135W and 90W, yes the 90W run slow but not REALLY that slow. It's just that it's without turboboost, but the i7 cores are using fully.
There is no configuration. I dont use power manager, uninstalled and disabled the services.
because if u use 135W, sometimes it doesn't automatically on the turboboost due to powermanager conflict with windows 7 built in battery manager.

I also have a W510 that is having trouble. During boot up, there is a message displayed before the Lenovo bios logo appears stating that I should only use the 135 watt power supply which came with the system. This message appears BEFORE the operating system boots, so I know it`s definitely not software related.
So, i figure that after 5 months, my 135w power supply is pooched. I order a replacement.
When I receive it, I unbox it, plug it in, and boot my system.... The SAME message appears. It seems that something is wrong with my motherboard.
I contact lenovo support. They suggest a BIOS update. After the BIOS update, it still comes up with the same info, however the BIOS 135W power supply warning now has an option to not show this warning in the future.
So, when my Lenovo W510 is plugged into either 135W adapter, my system is running at reduced performance. If I need higher performance, I unplug the adapter and run on Battery power for a couple hours. There is a HUGE improvement in performance when I`m on battery power.

I thought I was the only one.
My w510 works all day on the 135W or battery but on the Lenovo brand 20V 90W, it gets a little quirky. Some things lag like opening a RAW image in Photoshop (even though they open fine on battery). Then for no reason it just freezes and the only thing I can do is hard power it down.
