Bought this notebook at the KL PC Fair over the weekend. Prior to purchasing this notebook, I was deciding whether to get the ASUS A42JR (i5 version) or LENOVO G460 (i5 version). The ACER & LENOVO was priced similar at RM2699 while the ASUS is at RM2899 (ATI 512MB) / RM2999 (ATI 1GB). Frankly I prefer the keyboard on the LENOVO G460 as its typing feel was very similar to desktop keyboards. Performance wise, Windows 7 rated it with 5.0. Surprisingly, for the ASUS, its Windows 7 rating was only 4.9 where I noticed that the notebook faired lower in 3D Aero performance as well as Processor Calc per sec compared to ACER.

Having read several reviews on ASUS A42JR pertaining to short battery life & my other notebook being ASUS K40AB (AMD Turion 64) which could only squeeze out 1hr 50 min on battery power, I felt that the A42JR notebook could not justify the extra asking price over the competition. I wasn't convinced by ASUS of being a better quality noteboook than ACER sales pitch. What I didn’t tell the sales person was that my ASUS K40AB got fried on the 2 day of ownership which was replaced with a new set. Powering off the K40AB & left it for full charging somehow caused the burned circuit & the notebook couldn’t be powered on again. So is this quality issue or just pure bad luck? The 2nd new unit worked fine until today however.

Anyway back to the ACER, the machine ran hot with the ATI graphic card enabled especially at the left palm rest area which made typing unpleasant. Battery life as reported by professional reviews put the ACER at about 3hrs of actual use (gaming + wifi). However if you put the machine on power saving mode (pressing the” P” button), disabling the dedicate graphic card in favour of onboard Intel GMA & tweaking the power setting, LCD brightness, disabling the CD-ROM made a significant changes in the battery power life & heat output. Now if I could totally eliminate the heat from the left palm rest area that would be ideal. I notice most of the Pentium or i3 notebooks don’t suffer from as much heat problem at the left palm rest area as the i5 although both chips is rated 35W. Perhaps I need to open up the machine & mod a better thermal shield & risk void warranty....

Snap shot below, 99.6% of battery charge could power the notebook for another 5.5hrs (typing work & surfing with wifi on). Very impressive indeed as such battery power life is close to the low performance Intel SU / Atom chip notebooks.

Overall I'm happy with this ACER as its been on for nearly 32hrs straight.... icon_rolleyes.gif

Thought there is not 4745 club. Finally there is .... Nice

Totally agree with you about the heat from left palm area. I am guessing that part is the gpu????
I think i need to get DIY cooling fan and place a fan right under the left palm area of the laptop.


how about this image for the thumbnail of this thread?

Well, both GPU & HDD generate heat as we speak...but for games and intensive use of the GPU, it will be hotter than HDD..for HDD, the temp seems good as in idle @37C (guessing in a cool temp room)...

just click the Fn+F3 key thingy, ya so I got the 4745G also. I agree when playing intensive games, the laptop tend to get hottt, especially the air vent (thats what its call right) the one to the left hahaha. But gaming wise, I'm rpetty happy, can play crysis on high, Sims 3 no problem, COD6 ...really great laptop smile.gif

That kind of hot running notebook is not my cup of tea. It won't last very long in my hands at that temperature. Looking for notebook that can last for at least 2 years (without having to claim warranty - the last thing I want to do - time wasting).

For the warranty. Is it come as standard 3 years or you get an extended one?

extended for free right now. haiz.... if this notebook so hot, then i may change my mind. coz i need to use it daily at university (watch movie, surfing net, fb games or maybe gaming if free). i worry overheated, if i sitting below air-cond i think it should get better, right?
btw if really say so, then i may buy a Cooler Master Infinite 4sub for this notebook at home.
