Crysis 2 kills battery while it's plugged into MAINS.

Wow, gaming for about 30-60 mins on Crysis 2 kills my battery, while it's plugged into the mains, ? i stop play, check my battery, it's on like 34 %, this game is a power sucker for sure.........

I am overclocking my card as well, 650 core and 1000 memory, bit worried about doing this though, but my temps are not rising above 75 degrees for the GPU, CPU gets about 87.

200 mhz more on the memory is what i'm worried about, the 650 on core is fine as my 5650 is underclocked to 450. i can't go any higher than 650 though, it locks up my laptop.

 

What happens when you take the battery out?

 

I wouldn't like to try it to be honest.

 

I 'm not aware of any laptop ever used the battery as a secondary power supply... When you plug your laptop in, it is essentially running just like a desktop computer with the battery just sitting there unless it is being charged... That amount of battery usage seems typical of gaming for that amount of time on a laptop that is not running off of its power supply, so I suspect that your PSU is either broken or was not plugged in while you were playing.

Unplugging the battery should cause no issues if your PSU is functioning properly.

 

Yeah that's what i was thinking? i will give it another go now for an hour see what happens, i'm on 100% battery right now.

 

Your PSU is overloaded...

 

i think most laptops can pull power from the battery if the power supply gets overloaded, but it shouldn't under normal use.

normal use could be playing crysis without overclocking, for example.

i know apple laptops can do this.

 

i tryed to run my laptop on a 65w adapter yesterday cause i forgot my 220w monster

my laptop jus kept turning the adapter off

 

I believe some Thinkpads also use a tiny bit of battery if power usage spikes up, but the battery used in those circumstances are single-digit percentages--it shouldn't be using so much power from your battery if your computer is plugged into AC. Are you using the AC adapter supplied with your computer?

 

overclocking is overpowering your psu and could cause damage over long periods of use.
if your not using your battery remove it. if it cant handle it without the battery in dont overclock.simple.

 

some compagnies also provide beefy psu just to make sure (especialy dell/alienware) mine came with a 220w adapter (likely capable of pushing 240-260w) but even under heavy OC from both GPU and the CPU it pushed at max 178w
