Weight of T40 without battery...?

[T7TrainingSystems]

I'm travelling next month with 6 x T40s (as well as 2 x T23s and 2 x T30s) and I'm having trouble finding a definitive answer about how heavy T40s are without a battery.

Anyone know? I'm planning to put them in a well-padded hard travel case without their batteries so I can make it under the excess luggage limits...

What I'd really like to do is buy some dead batteries, remove the cells and just keep the battery case in the laptop so it doesn't have a big hole in it.

Anyways, anyone know how heavy they are without battery and have any advice?

Cheers!

My T42's 6-cell battery weighs 309.6 grams or 0.683 lbs. I have weighed the following T4*'s with optical drive and 6-cell battery:

T40 with XGA = 5.04 lbs
T42 with SXGA+ = 5.17 lbs
T43 with SXGA+ = 5.17 lbs
T42 with UXGA = 5.44 lbs

I've never weighed a T40 with SXGA+ but my guess is it's somewhere between 5.10 and 5.15 lbs.

Have you considered removing the optical drive as well? It weighs 0.40 lbs. With both the battery and optical drive removed, an XGA T40 weighs 5.04 lbs - 0.683 lbs - 0.40 lbs = 3.96 lbs or 1.80 kg.

Thanks for the great info. I reckon I might just be able to sneak under the baggage limit with a little luck.

I'd love to remove the optical drives but these are training laptops and my training books come with CDs. I could use .iso disc images, but it would confuse students - I'm sure I'd get too many questions of "My CD drive won't open" and when I explain why, too many thoughts of "What the hell's a disc image?" LOL! Best to keep things simple and predictable.

Thanks for the data!
