Note:
The download file will be store in your temp directory with *.tmp file(size about 130Mb for DXKC1).
It will be decrypt when the update process begin and will be automatically deleted when the update process successfull.
if you want to get the .tar file, just wait when it decrypt in same folder and it will create an new folder in you temp. copy it as fast as you can.
if you can get the tar file it will make you able to flash it with odin. or you can download it manually from samfirmware.com and follow the update instruction from that site.
based on the info from ace forum in kaskus.us a single file *.tar only can be updated if the previous firmware is installed but if you downgrade from the new firmware version so you must find multiple file firmware that contain file modem,csc,pda,ops,boot…

Mini review:
(Background:Since there is no adequate review on net -
Da** to lenovo and magazine that related to computer that dont provide review for cheap/value laptop)

Start……………..
I just brough this lappy yesterday in JEC fair at yogyakarta yesterday. it cost US$ 699.
After I get this lappy I installed it with windows XP Pofessional SP2 that has been slipstreaming with SATA Driver.
Installation in XP was walking very nice and smooth without any problem except for the Stupid Conexant AUDIO DRIVER. But i bring that lappy to the support center and they help me to instal it in no time. The os installing is successfully completed.Here is the step for install the audio driver:

How to install conextant audio in lenovo G450:
in normal click setup.exe you willl got error messege: cant install because no correct driver for this media bla bla….
to instal it you should open device manager–> Look for unknown device–> righ click–> update driver–> and browse(have a disk install) to your audio driver–> file with “INF” extension is the driver. so make sure to show file extension in folder option. After window copy the driver restart your lappy and binggo the audio will work perfectly.(You dont need to install
XP Hotfix kb888111 if your unknown device has been detected as HD audio..).

Tips:
(if you download the “exe’ file from the web page you still able to get the “inf” file by extract the “exe” file with winrar)

Lets Go to this laptop Body and Hardware:

Body:
-With the grey steel stye, This laptop look very nice.Here some picture of this lappy:

LCD Panel:
-The lcd screen is the bad part of this lappy because it look foggy. it mean it like a thin membrant when you look the lcd
screen(especially if you have no background). The Lcd panel is easy to shake if you typing a little bit hard. I think the
hinge is not soo tight.
-Hey lenovo designer you should think to make a better hinge for next notebook.(Dell d630 is good example fo the great
hinge)

The Keyboard:
-The keyboard is so comfortable maybe as good as logitec standar keyboard(at least 90% of it softness and comfortable)

The shortcut Key:
-there are five button except the keyboard, that will be:
1. The Power button
2. The Lenovo One Key recovery-but this not working in win xp because the software only for vista or higher
3. Mute button-only using touch sensor
4. Volume up-also using touch sensor, and
5. Volume Down-also touch sensor
The volume sensor using white led background

The Indicator:
-There are 6 white LED indicator:
-Near the lenovo one key button:
1. Cap lock indicator
2. Scarrol Lock indicator
-Near the touchpad:
3. Power Indicator
4. Battery Indicator-will turn into red coluor if the battery status is low
5. Connection/wifi indicator
6. Hard disk indicator

The Temperature;
-During first time Xp instalation the lappy got warmed in left touchpad side and in the middle below of this lappy but it
still in tolerable temperature because we access the harddisk and optical drive to much when installation.
-For the normal use I also feel the left toucpad side keep warming(it is the harddisk position-base on the manual)
-The Everest ultimate temperature read for the normal use:
hdd: 45c
processor core: 45c
1 core :39C
2 core:39 C
- GPu temperature: unknown…..maybe there is no sensor for integrated GPu

The Camera
-Lenovo easycamera 0,3 Megapixel surely not a good option if you like to use video conference. Acer notebook camera is alot of better that this camera. but since i not always use in camera it will be no problem.

The optical drive
- As mention above this laptop use Matshita DVD RW (popular name: panasonic dvd rom) as the optical drive. so far this dvd rom is work very well (maybe the best i ever had). reading and writing to DVD and CD is very fast, but i have no complete Spec for this one. maybe if you have you can post it here. Ssttt my friend using CQ 40 324–> the dvd rom is soo slow. i even can make a cup of tea before it can read a cd rom.

The Battery:
This battery life is abouth 3 Hour(I try with my modem online). If you play games the battery life will be shorter because the GPU and CPu are eating to much energy and become very Hot
Very Very Important Tips:
To get the optimal battery life and Battery Age : please Don’t Plug your battery when you play games-just use your power Adaptor. This secret jutsu (techniq) will make your battery become long lasting at least for 3 years)

The Software:
As I write above, I use the Windows XP Professional SP2 as the OS. When I boot the laptop it only take less than 30 second to enter the windows(after windows XP welcome screen) with avira antivir startup. this amazing fast. To keep this lappy run well i usually maintenace it with tune up utilities. Running warcraft is very easy with this hardware. To see how far this lappy can Go the I install The SIMS 3-it also run well in middle detail setting (high detail make the sims 3 become lag)

Here i show the result for CPumark with cpumark 2.1 (T6600-lenovo g50) compare with T7500-dell d630):

Result from Cinebench R10 for lenovo g450:
cinebench R10

Result from 3dmark06 for lenovo 450 :…..
ehmm i dont have this software and it to big to be downloaded with my limited bandwith
hehhehehhehehehheheheheh

the other review will come next-oh my god i running out of im3 pulse [T-T] {T-T}……………
