Few Issues

Hey ppl,
Im having some trouble with my m15x...
1st. When I close the lid and reopen, my wirless,bluetooth,ect buttons won't work.
2nd.My volume touch thingy its buggy and sucks.
3rd.All my battery options are set to Max Performance but my clocks drop to 275/300 when unplugged.

Any help with any of those?

 

1) It's a Vista issue I believe (driver related), though I don't know the solutions.

2) Ya, the volume slider sucks. Poor design. Just look around the forums, almost everyone complains about it.

3) This is known. It's a "feature" to save battery life. Sadly, there's no work-around for it at the moment. Honestly, I think it's false advertising to not warn about this on they're website somewhere.

 

thnks for the help man! still this means I cant fix any of them

 

Number 1 can be fixed most likely, I'm just not sure how, but if I find anything I'll let you know.

 

#3 only occurs with 8700?

 

It occurs with the 8800 for sure. I'm pretty sure it doesn't occur with the other cards, but I'm not positive.

 

so is it only AW or all 87 8800 cards do this? XPS? Sager?

 

1: this option has been fixed in the x32 bios update. just download and install.
this will halp no 2 aswell a bit. the x30 only fixed the overheating issue, but now they fixed the touch controls after coming out of sleep issue with x32

3rd: that happens with all laptops. its a phisicly impossible thing to do. the gpu uses more watts than a battery can supply at max, so it has to downclock to cover itseld. as far as i know, this happens with the 8800 aswell

 

well even if your gpu downclocks when unplugged i believe, if it needs the power in a game, it will clock back up when needed, it should automatically when a game is being played, thats what i noticed in many laptops. Is it downclocked while playing games also?

 

unfortunatley halogod, it will just most likely, lose FPS during super intensive moments to compensate.

 

it keeps the clocks at 275/300 when playing , and thx everybody im dling the bios update as we speak

 

the bios update wont fix this issue though, you know right?

 

@Everyone - #3 happens on all laptops. On my M9750 SLi is disabled and the card downclocks when I unplug it. This is to save battery life, and every laptop that I have ever used has done this.

 

And I think that sucks. We should have the choice to have it downclock. I know the battery would hardly last at all if it didn't do this, but we should still have the choice.

 

It isn't a matter of the battery lasting, it is a matter of power density of the battery. A LiOn battery simply cannot deliver the wattage that is required to run an 8800M GTX or 7950 GTXs in SLI without exploding. If you tried to force it to...be prepared to function without a few fingers or a lap.

So this isn't a matter of "This sucks, we should have a choice", this is a matter of limitations of technology. As was stated earlier in the thread, battery tech isn't keeping up with the tech that it is running.

There are other options, but they won't be in laptop batteries for another year or two minimum (See: http://en.wikipedia.org/wiki/Eestor for info on the most promising supercapacitor that may replace batteries soon in automotive and industrial applications).

So, I apologize if this got long-winded, but I figured I should clear this up: it's not a matter of saving battery life so much as it is a matter of keeping the draw on the battery below what it can supply.

 

what if you use one of those 3rd party external batteries?

 

You'd still run into the fact that the underclocking we're talking about is probably part of the card BIOS and hence very difficult to circumvent (Maybe? I could be wrong here). So, while a third party battery might be able to supply the wattage, you'd need to be concerned about battery life then, overheating of the battery(/ies), and a whole host of other things.

All-in-all, I don't know how much this is a worthwhile endeavour. When you're on battery, things are gonna clock down. I would take that as part of the package when dealing with notebooks.

If you are determined though, I would love to hear about what you did to get the cards to run at full spec on battery.

 

No, I meant a 3rd party external battery. It's like plugging the laptop into a wall socket. Like this one:



It plugs into the notebook externally:



This is just one particular brand and model. There's a lot of other universal laptop batteries out there.

 

Ahh, ok. Well, the same things can happen. If the laptop is drawing too much, the external battery can over-heat and explode. Problem now is that the laptop isn't going to downclock if this starts happening so it is up to you to ensure that the external battery isn't being overtaxed.

Check the max system draw under heavy load, and the max wattage that the external battery can deliver. This is (as far as I know) the only way to avoid such a situation.

 

Well the point is to check that the battery is providing the same output as the laptop's power adapter. That should prevent explosions (hopefully).

 

Yup, that would do it.

 

1. This problem has been fixed with the latest X32 BIOS
2. Everyone is having the same problem
3. This happens with my m1730, m15x and dv9700t and there is no way to get around it (so far).

 

the external batteries that you can get are pretty much just big, heavy litium ion batteries, so they will have the same drawbacks. You can only make a li ion so big, thats why they are made of multiple cells, ei... 6cell, 8cell 12cell.

The only other battery type available at the moment is lithium Polymer. These have almost the exact same output and battery life as lithium ion, but they are much lighter. And so, they are much more expensive. The only vendors i know of that use these in laptops are apple in their macbook air.
