C laptop screen 15.6 " Lenovo B570

C laptop screen 15.6 "
     * Weight 2.35 kg
     * 2000 MHz Pentium processor
     * 2048 MB of DDR3 memory
     * Hard Drive 320 GB
     Optical drive DVD-RW
     * Bluetooth, Wi-Fi
Advantages: Modifications in this model very much, I got Lenovo B570e-59329545 (black). Bought for 14.1 TR
1. Price is not much bite for such a filling (see below).
2. The processor is written (we believe) a Pentium, not Seleron (in my case installed percent V940, 2000MHz = 20 * 100 MHz, L1-128kbps, L2-512kb, L3-2048kb).
3. Two graphics (integrated and discrete). Built on INTEL HD Graphics Family (directly in percent, the memory hawala course of RAM computer), and discrete Geforce 410M - has 1024MB of internal memory. Moreover, the laptop automatically (!) Switches with built vidyahi the discrete when running 3D applications.
4.Nout absolutely no noise and virtually no heated (although the turbine on right away when you activate the discrete video card).
5. Keyboard - Premium island type has additional buttons tsifiri.
6. The speakers are located at the keyboard (next to the hot keys) - so the sound is not the bottom, clear sound and volume, set 24bit 44kHz.
7. The presence of HDMI and standard VGA output pleased.
8. The hard drive is large enough company 500GB HITACHI.
9. 2GB of memory standard, but DDR3-1333 (PC3-10600) SDRAM (Ramaxel Technology)
10. Not a bad matrix monitor LG Display LP156WH4-T, sufficient contrast.
11. The touchpad is large and with Doodle - although I yuzayu myshu.
12. Gigabit NIC RTL8168/8111 PCI-E Gigabit Ethernet - nice.
13. Smart wi-fi with a bunch of settings Broadcom Corp BCM4313 802.11b/g/n
14. Battery SANYO-L09S6Y02 I trained immediately after purchase Nouta in three sets (full charge-discharge) - holds 3.5 hours at an economical settings Wind.
14. Most importantly, I almost forgot ... Windows was preinstalled - bought DOS version. Driver disk was included.

Disadvantages: 1. Zvuchka Realtek ALC272 behaved strangely (like power-saving mode) - to play a standard system sound (such as clicking open a folder) in columns Nouta sound will be heard (and after the sound and off) speakers.
2. Linuh not set (nothing to say), but the HR tried. I must say - a 410M graphics card drivers for XP in nature! Do not look. Piggy eternal lovers have juzat only integrated graphics from Intel father.
3. From the system disk, I used only the driver for card reader Realtek (standard card readers seem not found), everything else is set to Drayverpak as on the supplied CD NOTIK many old (no automatic installation). Firewood on Geforce rocked the site Nvidia.
4. Could not find a driver for "unknown device" ACPI / VPC 2004. This miracle was Lenovo ACPI Compliant Virtual power Controller (damn it!).
5. I want to 4 USB ports and, damn it, there is room left in the case. Why only three USB and such tight? But still funny - two USB (right to) near the laser drive and tray touches my stick! I myself drive an unknown manufacturer PLDS DVD-RW DS8A8SH.
6. Powered USB ports seemed rather weak, had to find a thick cable for the external USB hard drive.
7. No bluetooth, sorry - a nice change.
8. No arm off wi-fi, you can disable the BIOS in Windows or in the hardware list.
9. In the BIOS, before installing the system, the controller board to include notebook mode IDE - well, such as disk partitioning using LiveCD to XP, for testing "iron" under DOS.
10. 0.3 megapixel webcam - for Skype except ...
11. In Nouta slightly sharp edges - but it's an amateur.

Comment: Performance Test Results Nouta Win7_32:
Calculations - 5.8
Access to memory - 5.5
Aero (I yuzayu classics) - 4.4
3D graphics - 6.3!
Exchange with the disk - 5.9
