it depends on your usage, if you set to Discrete graphic all the time, battery die fast. My experience:

Battery life:
No wifi, light usage: 8 hours
Wifi, light browsing: 6 hours
Gaming: 2 hours max

Other owners experience:

"Best experience using 4820tg while working.. The battery can hold up from 9am-6pm with 6-cell battery on WiFi mode."

"Turn on ATI display card (High Perfomance Mode) is around 3+- hours with playing games, if turn on Intel on Board display card (Save Mode) can be stand for 6+ hours."

"Just thinking to share the experience on my 3820TG during CNY. Using intel graphic to watch movie and internet surfing, the battery can last until 7 hours with lowest brightness setting. Using internet in Hong Kong airport while waiting the flight for 3.5 hours and watching movie in the plane for 3.5 hours..."

You should fix your cam and not moving it around for better video review

Just pick the notebook and play it around in front of fix cam and bring it near or further for zooming purposes

Hahaha. I'm using an iPod nano T_T Sorry for the vertigo effect.

No problem. Appreciated of your great efforts to add poison here

2nd video covers the keyboard, touchpad, weight, power brick & bag

ya , i should stop viewing this thread , poison me day by day ......

Just get the antidote

how about part 3 on gaming, GPU temperature, gaming, GPU temperature and so forth?

walao nice vid review man. thanks

now, should i go with 14" or 15"

but the monitor really glossy eh, i prefer a matte ver. last time i bought my dell laptop there is an option to opt for it

but i dun think lapotp vendor produce a matte screen anymore. do they?

Well thinkpad x220 is matte screen, sager has the option to customise matte screen also..

would matte screen protector do the job?

thinkpad x220 not available in malaysia... it's a pretty cool machine...

Most of IBM laptop still using matte screen

My office gave me a T410 to use for official stuff. I love the matte screen. And the screen resolution is 16:10, and not 16:9. I think only Business level laptops (lenovo thinkpads, dell latitude) have matte screen option.

I wish laptops manufacturers give the option for non-glossy screens.

Somehow Lenovo's name has gone up a lot since their acquisition of ThinkPad lines.. Lol

Yeah it is called Lenovo nowadays but IBM name still stick to my old brain
