Yoga 500-14ISK's nVIDIA 920m overloading battery

[NsNidPL]

Hello,

after a lot of posts (they were going down and no chance for reply, sorry) about graphics card problem I have finally identifed what's wrong. The problem is that the nvidia card uses too much battery (overloads it, not just faster draining) causing in screen flickering. how do i limit the power of nvidia can use or other fix? or does that mean faulty battery?

EDIT: Happens on battery <20% even with nvidia disabled. I blame battery.

The battery voltage is average 7.8 v but i saw somewhere it should be 11.1. Is it normal?

Can you try following the instructions on this page and see if it helps?

Nothing. I visited every page about nvidia flickering, all drivers are up to date. Power Saver power plan seems to reduce flickering.

The battery is 7.4 v one. Should I replace it with a 11.1 v one?

PS: Following instructions? What instructions? there are just drivers and instructions for specific devices.

If you avoid powering up the NVIDIA card, the screen doesn't flicker then?

From an eBay seller , the battery says it should have a nominal voltage of 7.4 V:

So at the very least your battery is operating at normal voltages. I'm not sure if the 11.1 V applies to the Yoga 500 battery.

With Nvidia the flickering starts around 60%. With Intel HD only it starts at 20%.

And that only happens in games.

About the battery: A ha! Yoga 500 has 2 battery types to choose. The link you sent me is 30wh one. There are also 45wh batteries. My latop is an exhibition one and it has 2 years. I think replacing the current battery (30wh) with 45wh one could help. That's because 45wh ones are 11.1 v.

lmao that was cpu

i limited it to 50% and everything fine

but it's not perfect

[ColonelONeill]

Interesting; though I would still consider that to be unexpected behavior.

Lowering the CPU maximum multiplier will also lower the peak power consumption drastically, which may be what you're seeing.

I've connected my laptop to TV via HDMI and only laptop screen flickers. No. I will buy an 11.1v battery.

So, 11.1v APPILES to Yoga 500.
