T420/T420s

Sorry if this has been posted before. I'm so close to pulling the trigger but just can't decide on the T420 or T420s. I'm really liking the lighter and thinner design of the T420s. The battery though, concerns me.



I think the T420 can pull off 6 hours on the 6-cell no problem. But I'm not so sure about the T420s. Anyone know battery life of the T420s?

On this video, the reviewer state that the battery life of the T420s is around 3 1/2 hrs, that is an real world usage scenario and high brightness setting.

If you like the T420s so much, get it and bring both the notebook and the power adapter with you in your bag. I'm being totally serious.



Realistically, on average, T420s 6-cell pulls 4 hours. T420s 6-cell plus 3-cell pulls 6 hours, T420 6-cell pulls 6 hours, T420 9-cell pulls 9 hours.

If battery life is your deciding factor, it seems the decision is made if the T420s doesn't support the battery life you need.



The T420 is a mainstream machine and from all of the reviews so far it well built and a smart choice.

Simplest solution is to buy an extra 6-cell battery and throw that in your bag. Those batteries hardly weigh anything. The T420s though doesn't nearly have an edge on the T420 in weight (and maybe also thickness) like the T410s did against the T410.

^^^ Nah, as I said, bring the 65W adapter if one lusts after the look of the T420s. The 65W hardly weighs anything.

I've been in the same situation for the past week or so, and the argument that finally persuaded me to go with the T420 (though I've yet to actually place the order) was this. Low weight (i.e. T420s) wins if what you typically do is carry the computer around between a number of fixed locations (e.g. home, office, client's office) where you can strategically place chargers. Long battery life (i.e. T420) wins if what you typically do is carry the computer around between different locations where you may or may not have access to a power outlet, including places like airports and trains. My use profile is more along the lines of the latter.



It should be said, though, that it is with a tinge of regret that I turn away from the T420s. It is one sexy machine...

Or add the "Lenovo 90W Ultraslim AC/DC Combo Adapter" on the Accessories-tab of the T420/T420s configurator.

Leave your multiple AC adapters at home and only take one on the road! The Lenovo 90W Ultraslim AC/DC Combo Adapter can power your notebook, cell phone, MP3 player or other peripheral devices, when it is plugged into a standard AC wall outlet or the DC outlets available in automobiles and airplanes. It is Lenovo's smallest and lightest combo power adapter yet, so it tucks easily into your carrying case for travel.

(THis is really funny, Lenovo still linking to the IBM website.)

I've done the power adapter deal before with other machines. It's disadvantage is two fold:



-It's a hassle dealing with the long cord and takes about a lot of space compared to a slim T420s battery.

-Once the battery is dead you're tied to an outlet until it charges. With a second battery you just put that in are good to go.

^^^ OK, then, take both an extra (slim) battery and the (not so slim) power adapter with the (slim and sexy) T420s.
