I again installed 12.11 catalyst beta and again it shows 7700m series on device manager but it is not working "windows has stopped this device" after clicking on properties of it. Looks like i will have to wait until final driver arrives on dell's website.
our lappys are powerful - true
our lappys are power hungry - its not true
bcoz it depends on the way u use it. it consumes more power only when it is used i high performance mode but while using it in power saving mode it is just like another laptops even more efficient bcoz its i7 3612qm has tdp of 35w which is same as other dual cores. so in real
2.1x4=8.4 ghz consumes 35 watt and for ii5 2.5x2=5.0 ghz consumes 35 watt. hence it is more efficient
where d heck did you find this logic..
.
it does'nt work that way dude, 2.1Ghz 4 core means that 4 cores are simulating the working of 4 independent processors, each clocked @ 2.1Ghz, so the clock remains 2.1 Ghz only, it's just there are 4 of them of that much power, the clock does'nt add up, it just remains as it is..
yes ur right, except GT 640M is slightly faster than 7730M so 640 is supposed to be on no. 1
it's still not proven bro, if you are referring to notebookcheck, then that's very old data, only current data can be very reliable..
My 3DMark11 benchmarks shows my score as ~2.3k, which is close to 650m rather than 640m (
link), and that's with beta6 drivers i think, beta8 have some more improvements..
So, acc. to current data, 7730m>>>640m, till any of the 14R users post their scores here..
Hi,
I might be getting my laptop tomorrow..
Do i need to check anything when i get it and if so what???
yes, all those bloatwares that DELL gives to you pre-installed, remove them..
and partition disk acc to your need..
hmm.. ok true.. but still battery issue has to come some day .. say in 1 - 1.5 yrs if v hav gud gaming usage every alternate day... at dat time will aftr mrkt batteries work or need to buy genuine one only?? btw, how much they cost?? aftr markets are around 2k .. n is power adaptor covered in accidental damage / complete cover warranty for all 3 years as even power adaptors have same issue like one needs genuine power adaptor n it costs around 1.8k !!
it looks like laptop maintenancs would be around 3-4k every 1.5 - 2 years if really battery goes off in this period..
yes, laptop battery (it does'nt matter of which company they are) rarely last for more than 2 yrs nowadays...
A quote from
here:
Lithium-ion batteries age. They only last two to three years, even if they are sitting on a shelf unused. So do not "avoid using" the battery with the thought that the battery pack will last five years. It won't. Also, if you are buying a new battery pack, you want to make sure it really is new. If it has been sitting on a shelf in the store for a year, it won't last very long. Manufacturing dates are important.
Original battery will cost ~6k, and it's recommended to buy genuine only, though in some cases, aftermarket batteries tends to give same or more performance than original batteries @ third of the cost, but you have to check for it's compatibility on your laptop, otherwise it could damage internal components..
