Acer Aspire 4750Z review

Pros:

Acer Aspire 4750Z is an awesome budget laptop (21,600 INR on 1st Oct 2011) with all the necessary hardware features.This laptop is unique-as it has a latest Pentium dual core processor B940 (http://t.co/tGHhaH0G) launched in June 2011 by Intel.

Triple booting Win XP SP2 32 bit,Win 7 Ultimate 64 bit(Windows Experience Index out of 7.9 :

Processor – 5.8

RAM – 5.5

Graphics – 4.6

Gaming Graphics – 5.9

Primary hard disk -5.8

) and Ubuntu Linux worked as a charm.

The processor doesn’t heat at all ,battery backup of 3+ hrs(though in specifications it is mentioned 4.5 hrs).

Con:

In built speaker is poor(to watch movies, have to use VLC (Equalizer-Live)

Tips:

1>Change SATA controller to IDE from AHCI in BIOS settings (F2 while booting up) before installing any OS

2>Windows 7 drivers are there in CD supplied or here.

Almost all device drivers for Windows 7 is backward compatible for Windows XP too(use device manger>update driver>browse for driver files,in case of any problem).Only Graphics driver isnt compatible.

Download the following Graphics driver for XP:

http://t.co/yfY8o2rQ (Lenovo VGA driver-compatible with Acer’s)

3>To boost volume on win 7(on XP it is somewhat fine):

Right click on the speaker icon in the task bar and select Playback Devices .The Sound dialog box opens up- From the Playback tab select the Playback device >Properties>Speaker Properties>Enhancements tab Disable All Sound Effects

Also use VLC (Equalizer-Live)

So this one is cheap though power buy!

Available on Flipkart .
