Re: X220 cpu throttling problem

I guess it would be great if somebody from Lenovo would give us and update.

Re: X220 cpu throttling problem

[ Edited ]

seriously..

 

the reason why Apple is so sucessful besides its products being pretty is because of its superior customer service.  when iphone4 came out, it had a huge issue with its antenna.  with the user's "death grip," the signal strength drastically dropped.  what did Apple do to remedy that?  two weeks after this issue has been surfaced, they offered to give out free bumper cases to all of its customers.  besides that, the customer service at the Apple store is simply amazing.  have a problem?  one of the "geniuses" will get to the bottom of the problem.  if they can't, they just simply replace the product with a new/refurbished one.

 

X220 is a great product, but Lenovo should seriously address the problem that the customers are facing and come up with a solution or do SOMETHING aSAP.  even with a superior product, a business will not dominate its market without great customer service.

 

i'm not a business major or a businessman, but it's a no brainer..

this ish is so frustrating.

Re: X220 cpu throttling problem

I think that you may be overstating this.  Yes, it's a problem but it actually is a fairly minor one in the grand scheme. Look at the conditions under which you have to actually reproduce it.  I'm an software developer, written code on my x220t, played a number of hours on my x220t and I simply have see no manifestation of this problem. Indeed when I ran the test I did see brief down throttling but it wasn't permnent and as I've said I've played modern games on this machine in Portal 2 and Super Street Fighter IV Arcade Edition and they ran very well actually.

 

So it's a problem, not a major problem considering that is an ultra-portable device not generally targeted for high-stress computing and it probably effects a very tiny percentage of owners.  I do hope that Lenovo does come up with a fix but I'd rather see them take the time and get it right rather than cause other issues for what i could consider a non-critical flaw.

Re: X220 cpu throttling problem

The issue is for those of us who are experiencing the throttling on a regular basis, and it's simply due to the fact that we actually chose to pay considerably more for our i7 models and, in many cases, chose this laptop over other competing models from other manufacturers thanks to the advertised specifications.

 

So yeah, it may not be a major problem for everyone involved, but it wholly depends on what your subjective use for the system entails.  And if it's a major problem for even a few people and it exists on all models, that makes it a major problem indeed.

The throttling isn't limited to the i7. It also happens with the i5.

 

From what I could tell from the posts on this thread, it is a power adapter problem. Throttling doesn't happen if the X220 is plugged into a full size 90W adapter but does happen with the other adapters (65W and slim 90W). Am I correct about this?

I'm afraid I'm with Heatlesssun on this one. While I've neither the time nor the patience to wade through all 400+ posts in this haystack looking for your specific needles :smileywink:, I have read a fair number of them, and I've seen no evidence of any real system problem with real world applications. In fact, just the opposite, with the system throttling back automatically to stay within the power provided by the standard small 65W AC adapter even under synthetic worst case loading with the battery removed (why do that?).

 

The X220 is billed as an ultraportable, not a power workstation, making small and light its top priorities, and I think most X220 users prefer the substantially smaller and lighter 65W AC adapter to the substantially bigger and heavier 90W AC adapter. I know I am, tickled pink that my X220 delivers blazing speed in such a small and light package. As I've noted earlier here, I'm able to run very demanding real world jobs indefinitely with both cores in Turbo Boost using the standard 65W AC adapter. While not without its flaws, the X220 is an example of excellent design, arguably the best of the many ThinkPad systems I've owned.

 

The simple solution for anyone concerned about the issue is to get the 90W AC adapter (available during the standard Web purchase for $51, afterwards for $60, or $20-40 online). At most this is a documentation issue in that Lenovo should disclose that, while the 65W AC adapter provides sufficient power for normal operation, the 90W AC adapter should be used for worst case loading.

 

p.s. Out of curiosity, what specific real world applications are you running that cause you to experience "throttling on a regular basis"? And specifically which less expensive i7 ultraportables with small power adapters did you pass over for the X220?

Hope that helps,
John

When will 'Throttlegate' be fixed?

Dear Lenovo, it has been quite some time now since this probem emerged and there is still no sign of a fix. LIke many other people, I cancelled my order for the x220, while others returned their machine.

 

I would still very much like to buy the x220 because it would appear to suit my needs - small, high powered, good screen with a fantastic keyboard. But I don't want to be irritated by a noisy, pulsing fan.

 

May I suggest you do three things. 1. Formally acknowledge the problem, not just via forums like this. 2. Explain what is causing the problem. 3. Provide a simple timeline when it will be fixed.

 

The longer Throttlegate drags on, the more tempted I am to look at other brands. But I dont want to do that because I believe that Lenovo Thinkpadsare the best designed products - when they work properly.

Re: When will 'Throttlegate' be fixed?

@Cuthbert288,

1. When I mentioned that the team is working on this issue, I guess it is consider acknowledging the issue?
2. Issue is caused by power drawn by the processor is higher than what the AC can provide thus causing throttle to prevent proc / planar / AC short circuit.
3. Team are doing a test on this, no timeline provided. They will be releasing a BIOS within next week or another. Currently still in testing stage.

Appreciate everyone's patience on this.

Re: X220 cpu throttling problem

I give you a real world example: Playing Starcraft 2 on low settings will result in throttling on my i7 machine with the 65W adapter plugged in. Running on battery is not much of an option as you are looking at 90 Minutes max with a fully charged 6 cell battery. If it was only for benchmark environments causing the issue I wouldn't care one bit.

 

Now since Lenovo has confirmed multiple times that they are working on a fix, why don't we simply wait and see. All these threats of someone returning their equipment, claims of other companies providing better service isn't getting us anywhere.

 

Thanks & Best Regards

Re: X220 cpu throttling problem

I heartily agree with Gundy.

 

JameZ, might  I suggest that one potential step that Lenovo could take in the future is a locked forum with a separate page for each laptop model.  In it you could list each problem confirmed by Lenovo as an issue and its current level of resolution.   The levels of resolution do not even need to be that detailed (something like "escalated to engineering", "problem identified", "solution in testing", and "resolved" with a link to a formal response).  Items marked as resolved could also link to a solution with links to drivers. 

 

Personally I am happy to wait it out, but it seems like there are a small but vocal minority of people who want near-daily feedback. To satisfy them that the issue is not being ignore, you could 'visit' pages with open issues every few days to update the "last verified that progress was made" date. Normally I would agree all of this is not necessary...it is a use of your time I would prefer be spent somewhere more productive!
