@notrox : I think I'm gonna go 4 the 4830TG

I'm Still Sad though Cause the 3830 lasts >12hr Idle  and >7:30 hrs Working

the other is 7 Idle 6:30 Working ,, But maybe 3830TG's Battery Wears off faster bcoz of Heat Thing

U're so Helpful Guyz , BIG Thanks

a little something to worry about 4830tg owners...so...according to CPU-Z, our motherboards are B2 revision correct?which has been recalled a couple of months ago due to degrading SATA/chipset flaw. now...if ur use Gigabyte SATA check utility, u can see that, ur primary HDD wud be connected to SATA3 port 0 and that SATA3 port 1 would have not accommodated any drive at all and ur optical drive wud be connected to SATA2 port 2. as shown and u can even see that the utility says the motherboard revision is B2. according to Acer (Sandy Bridge Recalls Support), customers can check whether their laptops are affected or not.  Technically, 4830TG's motherboard is affected and shud b replaced. So, i keyed in my SNID and S/N in to the empty box, it states that my unit does not require any service.

so..how? our optical drive is connected to the flawed chipset. it will definitely degrade over time.

cpuz :
[attachmentid=2399916]

Gigabyte sata utility check:
[attachmentid=2399917]

Acer product adivisory:
[attachmentid=2399919]

so...knowing dat ur optical drive's SATA port will degrade over time, does it worry u?

da chipset flaw affects ONLY SATA port 2 and onwards. it does not affect SATA port 0 and port 1 as stated by CNET

and our optical drive is connected to SATA port 2 according to gigabyte utility...

and i quote CNET :

Issue: Affects SATA ports 2 through 5, not ports 0 and 1. Most laptops have two SATA devices, such as a hard disk drive and optical drive that would be using the unaffected ports 0 and 1. That said, Sandy Bridge-based systems with more than a couple of SATA devices could potentially be affected. The data itself is not affected. So, if a consumer had an affected system, data could be accessed by moving the storage device to another system or a working port.
