Same problem here. EVERTHING else works so far! I think they just need to fix it. Since switchable graphics don't work I cannot seem to change brightness. Trick is to turn off screen with Fn + F2 then adjust it to the brightness you want then Fn + F2 again. Have fun everyone. I'm pretty happy even though switchable graphics doesn't work yet. Drivers look promising though.

Switchable graphics & Win 7 on U330

2009-10-22, 20:52 PM

All,

 

Let's start a separate thread on U330 issues under Windows 7 since this long running thread focused on the battery.

 

Please feel free to participate in the Windows 7 Launch event discussion - I think general or windows specific questions are appropriate for that board, while system specific issues probably most fit on this board.

 

So, I'm hearing two issues - brightness hotkey controls under Windows 7, and switchable graphics driver not working?

 

Probably want to make those two separate threads. 

 

Mark

Mark_Lenovo,

 

The link for the switchable graphics issue (and other graphics card related issues) is http://forums.lenovo.com/t5/Windows-7-Launch/U330-Windows-7-drivers-finally/td-p/167163

 

If you could please give us some updates and a forcast of what we should be expecting that would be great.

 

 

Problems:

1. Switching graphics

2. Brightness Control

3. Can't reboot, stuck on black screen. 2 other people so far on the forum have this issue

I'm using Win 7 32 bit Home Premium

Re: Switchable graphics & Win 7 on U330

So the new W7 drivers were a bust until the new ver.67 BIOS came out early yesterday. Once I got this flashed and reinstalled the proper drivers, almost everything seems to work as it should. In W7 x64, I'm able to get my draw down to around 15mW/h on the ATi card and about 12mW/h on the integrated card. However, using RM CPU Clock Utility shows that my FCC is still ranging wildly; from ~51K mWh to ~43K mWh, when the designed capacity is something like 56k mWh. It's been this way since I got the machine and I'm convinced that there's some kind of dischord in the handshake between the battery and the computer. Perhaps firmware/BIOS? Are we no longer adressing this issue? Is Lenovo still shipping U330s with this battery knowing that it is faulty?

Re: Switchable graphics & Win 7 on U330

Hi everybody!

 

Some members of this forum, including me, waged this "war" for issues concerning U330 almost since it was released. A lot of words has been said, not always the pleasant ones, in Lenovo support/engineer team direction, and in the light of latest driver/bios releases i wanted to take a voice in this still ongoing debate.

 

This latest drivers+bios release fortunately made the transition from Vista to W7 almost painless. Giving the U330 users the 5 hours of battery life. The VT blooper has been fixed. System sounds problem partially addressed (still dont know why You cannot fully disable the battery plug sound through bios).

 

The new Energy Management gives us some hope. On mine W7 i get 10K mWh while writing this post with Intel GPU/wifi enabled/ screen turned down to 0 and super power saver mode on. Without wifi i can get even less. I suppose that most users could reach this levels. Unfortunately it's hard to say what gives us less drain: is it less needy W7 or new PM. Since the advertised 5 hrs is reached i guess there is no point to argue anymore. Even though if it's the system that is causing the gain, we could still theoretically squeeze more juice (ah... the neverending greed).

 

It took one year to get to that point. I'll leave that with no comments.

 

Recently, for testing purposes and thanks to Lenovo courtesy, i've recieved  a recalibrated battery from the factory that holds 58K mWh of fully charged capacity. With this new drivers in hand i'll put it to the test and see how it performs in two-three weeks time. There is still the bigest flaw unadressed. The rapid battery degradation. Unfortunately the 3% fix does not work in normal conditions.

 

Anyway: i'd like to thank Lenovo support for what has been done. Some special thanks goes to Mark Hopkins, who has been there all the time.

 

I'll post You my test results in a few weeks time.

 

Regards,

 

Jacek.

Re: Switchable graphics & Win 7 on U330

Heh...

 

Even i didn't think that i'll be here as quick as this...

 

After a short test i've come across some incorrect behaviour. Please anybody check if You're experiencing the same thing:

 

1. After a clean restart turn on the Rightmark tool.

2. Switch to super power saving and Intel's GPU.

3. Wait a while and write down the discharge rate after it stabilise (mine is at +-10K).

4. Close the lid untill the laptop goes to sleep and the led starts to blink.

5. Open up the lid, wake the laptop up, and wait untill the DR stabilise. (You may need to tone the brightness down to 0 again, also check the Energy Management, as it may not show any of the power plans selected, thats cos RM can alter the plan, if so, turn the SES again) Write down the result. Mine is at +-16K and doesn't go down. Odd isn't it?

6. Switch back to ATI GPU and write down the DR. Mine is still at 16K.

7. Again switch to Intel GPU and watch the DR. After a few seconds it drops back to the level noted in point 3.

 

If that is what You experience (the DR may vary from mine, but the difference between before the sleep and after is what matters) there is some bug that causes to wake up both or just ATI card after the sleep regardless of which one was used before.

 

Please check and post.

Re: Switchable graphics & Win 7 on U330

My old baterry charged to 33% of nominal capacity only. I've recved new battery from Lenovo that holds 58920 mWh of fully charged capacity (designed capacity: 56160). After few fully discharge, my fully charged battery has 53710. After each charging is less. Question: WHY?

That's the question we all want Lenovo to answer. My replacement battery did the same, in April it was up around 58,000 and has now been reduced to 44,000 in that time (by June it was down to 48,000). Full drain "resets" pull it back up to around 48,000 but within a couple of charging cycles it drops back down.

 

These batteries are faulty and because of the months and months that Lenovo has been denying that there is an issue rather than recalling the batteries and replacing them with ones that work I will never buy a Lenovo product again and have advised anyone who will listen to stay far away from these products.

Re: Switchable graphics & Win 7 on U330

Without bringing up my own issues with the new Windows 7 drivers, I'd like to know where we stand on the battery problem. This was the original issue, after all. The entire reason switchable graphics are important is to preserve battery life. But if the battery itself is cannibalizing itself on every recharge cycle, than the point is moot.

 

I've done more testing than any consumer rightfully should have to and I've still come no closer to a solution to this battery problem. When is Lenovo going to own up to this? Or are they settled on letting us perform their QC indefinitely, without any word on a proper fix? None of the powersaving options impact the fact that the battery itself is deteriorating far too fast than it should. My Asus laptop, which is one year older than my U330 still holds about 90% of its design capacity after many trips on the road, sitting in airports, on trains, planes, etc. To be perfectly honest, the majority of times that I've used the U330 on battery was when I was testing solution brought up here. It's just not reliable enough to bring with me knowing I won't squeeze more than 3 hours out of it. The battery has only been cycled maybe 2 dozen times, yet fluctates greatly, fails to achieve within 90% of designed capactiy most of the time, and needs to be conditioned far too much. Does this sound normal to you?

 

I'd like to know, since Lenovo is planning a model refresh for the U330 line, are the new ones shipping with this same battery knowing full well that the same problems will continue until they decide to fix things? Or have they acknowledged that this battery is faulty and changed it in the future models and at the same time, leaving all current owners in the dark with no fix in sight. Mark, I'd really like to hear your take on this as you're usually the man with the answers.
