Basic Specs Compaq PRESARIO CQ71-425ER
Type:
notebook
Operating System: An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a component of the system software in a computer system. Application programs usually require an operating system to function.
Win 7 Home Basic
Processor Compaq PRESARIO CQ71-425ER
Processor: Processor - is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.
Pentium 2200 MHz
Processor Model:
T4400
Number of Cores:
2
L2 cache:
1 MB
The system bus:
800 MHz
Chipset Model: Chipset is the name given to the set of chips (hence its name) used on a motherboard.
Intel PM45
Memory Compaq PRESARIO CQ71-425ER
Memory:
3072 MB DDR2
Maximum Memory:
8192 MB
Number of Total Memory Slots: Sometimes the best way to determine how many memory slots are in the computer and how many are available for upgrade is to open the computer and examine the computer motherboard.

Display Compaq PRESARIO CQ71-425ER
Display:
17.3-inch, 1600x900, widescreen
Display Screen Type: A display screen made with TFT (thin-film transistor) technology is a liquid crystal display (LCD), common in notebook and laptop computers, that has a transistor for each pixel (that is, for each of the tiny elements that control the illumination of your display). Having a transistor at each pixel means that the current that triggers pixel illumination can be smaller and therefore can be switched on and off more quickly.
glossy
Backlight Technology: An LED-backlit LCD is a flat panel display which uses LED backlighting instead of the cold cathode fluorescent (CCFL) backlighting used by most other LCDs.[1] LED-backlit LCD TVs use the same TFT LCD (thin film transistor liquid crystal display) technologies as CCFL-backlit LCD TVs. Picture quality is primarily based on TFT LCD technology, independent of backlight type.
LED
Graphics Controller:
discrete
Graphics Chipset Model:
NVIDIA GeForce G 103M
Graphics Memory:
512 MB
Storage Devices Compaq PRESARIO CQ71-425ER
Optical Drive Type: In computing, an optical disc drive (ODD) is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Some drives can only read from certain discs, but recent drives can both read and record, also called burners or writers. Compact disks, DVDs, and Blu-ray disks are common types of optical media which can be read and recorded by such drives. Optical disc drives that are no longer in production include CD-ROM drive, CD writer drive, and combo (CD-RW/DVD-ROM) drive. As of 2015, DVD writer drive is the most common for desktop PCs and laptops. There are also the DVD-ROM drive, BD-ROM drive, Blu-ray Disc combo (BD-ROM/DVDRW/CD-RW) drive, and Blu-ray Disc writer drive.
DVD-RW, internal
Storage Size: The amount of storage on a hard disk, measured in gigabytes and terabytes. Hard drive capacity is generally measured by the amount of data users need to store, which is usually much greater than the space applications take up.
320 GB Serial ATA
Hard Drive Speed:
5400 r/min
Communication Compaq PRESARIO CQ71-425ER
LAN/Modem:
Network 10/100 Mbit/s
Wireless Communication:
Wi-Fi 802.11g
Interfaces:
USB 2.0x3, VGA (D-Sub), HDMI, microphone input, audio output/headphone, LAN (RJ-45)
Expansion slots Compaq PRESARIO CQ71-425ER
Memory Card Reader: A memory card reader is a device for accessing the data on a memory card such as a CompactFlash (CF), Secure Digital (SD) or MultiMediaCard (MMC). Most card readers also offer write capability, and together with the card, this can function as a pen drive.
Yes
Memory Card Support:
MS, MS PRO, SD, xD-Picture Card
Battery Compaq PRESARIO CQ71-425ER
Number of Battery Cells:
6
Battery Chemistry: An electric battery is a device consisting of two or more electrochemical cells that convert stored chemical energy into electrical energy. Each cell has a positive terminal, or cathode, and a negative terminal, or anode. The terminal marked positive is at a higher electrical potential energy than is the terminal marked negative. The terminal marked positive is the source of electrons that when connected to an external circuit will flow and deliver energy to an external device. When a battery is connected to an external circuit, electrolytes are able to move as ions within, allowing the chemical reactions to be completed at the separate terminals and so deliver energy to the external circuit. It is the movement of those ions within the battery which allows current to flow out of the battery to perform work.
Li-Ion
Input Devices Compaq PRESARIO CQ71-425ER
Pointing Device Type: A pointing device is an input interface (specifically a human interface device) that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. CAD systems and graphical user interfaces (GUI) allow the user to control and provide data to the computer using physical gestures by moving a hand-held mouse or similar device across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on the screen by movements of the pointer (or cursor) and other visual changes. Common gestures are point and click and drag and drop.
