yes it's that,with T model we do not have optimus who drain the battery

[Sxooter]

Linux works really awful at the moment, as Optimus is not supported and will not be in the near future. You'll only get 2D working on the Intel chip, while the Nvidia cannot be shut down and drains the battery.

Bumblebee has been making great progress but still has a way to go. A lot of optimus based laptops can at least turn off teh GPU with acpi_call, but most can't use it yet. A few of the older machines can with bumblebee though. Look up the hybrid graphics mailing list to see how your laptop stands as far as support.

Been playing Deus Ex 3, works well (30-60 fps) but there's frequent loading in new areas. Not sure if it's the game engine or a performance issue.

There's one thing however, the thing's got an HM65 chipset rev. B2, the chipset affected by degrading SATA performance, as do most Acers today. This wouldn't be a problem when the SATA 2 ports were not used, but it seems the DVD drive is connected to the SATA 2 port, which is affected. Quite strange, why not connect it to the SATA3 port? As far as I know, it's not possible too change the SATA port for the DVD drive. I hope it doesn't affect performance too much. Maybe a DVD drive is too slow anyways to notice degraded performance.

Wondering if you guys have the same chipset and configuration.

Is this the same thing you're speaking about ?

If it is, it says I'm not affected..

Anyone know if it's possible to use a caddy to replace the optical drive with a hdd?
For the 4830T

Just installed mine tonight.
Seems fine but couldn't test it much tonight, will test more tomorrow.

Well the for users who's thinking about installing a HDD caddy like myself (OCZ AGILTY 3 + 640GB HDD), it would affect my 640GB HDD performance in the long run.

Cool!
Can you point me towards which caddy you used for that?

u need only to type "2nd 9.5mm caddy" on ebay make sure it's the 9.5mm thickness, as 12.7mm ones do not fit into 4830TG.

You're right, didn't know about the link. Will check mine tonight.
Thanks!

On a sidenote: I read an article from a reliable source which says that both Acer and Samsung (possibly more manufacturers) did not change the revision number in the BIOS, even though they changed to the B3 hardware rev of the chipset. Reason for this in business environments is backwards compatibility, for consumers it's probably cost cutting. In short, we probably got the B3 rev, it just shows up as a B2 in CPU-z. No worries.
