Acer Aspire One ram upgrade tutorial

admin — Thu, 16 Jul 2009 15:13:59 +0000

The Acer Aspire One uses an Intel 945GSE chipset which only supports 2 GiB of RAM.Installing memory modules larger than 2 GiB has caused the Aspire to fail the power-on self-test.
This video show step by step how to upgrade your Acer ASPIRE ONE ram to 1 GB or 1,5 GB (maximum). Inside this laptop there is a 512 MB ram soldered in the mainboard, so you can only add a PC4200 533 Mhz 512 MB / 1024 MB module. However, even Windows Vista works like a charm only with 1 GB ram in this netbook

Acer Aspire One is a line of subcompact notebook computers, or netbooks, released in July 2008 by Acer Inc. It is based on the Intel Atom platform, which consists of the Intel Atom processor, Intel 945GSE Express chipset and Intel 82801GBM (ICH7M) I/O controller.The line is manufactured for Acer Inc. by Quanta Computer,and is available in several shell colors: seashell white, sapphire blue, golden brown, onyx black, and coral pink. Its main competitors in the low-cost netbook market are the Asus Eee PC line and the Dell Inspiron Mini 9. Quanta will be phased out as a supplier to Acer; production of the Acer Aspire One line will be shifting to other manufacturers in 2009.
When either the BIOS password or the HDD password are set, they won’t be recognized unless typed in uppercase. If the password was typed with a mix of uppercase and lowercase, it will fail. If it happens with the BIOS password, the BIOS needs to be reflashed, if this happens with the HDD password, the password needs to be changed in the BIOS where the case mix will be properly recognized to a all uppercase password. Acer does not acknowledge the issue, does not mention it when customers call the support line and charges 125$ (US and Canadian customers) to reset the password
There are many people reporting problems with the LCD screen cracking during only 5–6 months of normal use. Acer are refusing to acknowledge that there is an issue with this product and are charging customers for repairs

HP Mini 110 All of what you need. None of what you don’t

admin — Mon, 29 Jun 2009 09:00:22 +0000

HPs new HP Mini 110 is a sleek, lightweight companion PC designed for Internet-centric consumers to stay connected to what is important to them, while at home or on-the-go. Offered in a variety of configurations and designs, the Mini 110 is small enough to slip into most purses, backpacks or briefcases and provides consumers with a choice of Pink Chic, Black Swirl or White Swirl HP Imprint finishes. The Mini 110 is as stylish as it is mobile, starting at 2.33 pounds and measuring just over 1-inch thick. With a 10.1-inch diagonal standard or optional high-definition LED widescreen display, a keyboard that is 92 percent the size of a standard notebook PC keyboard, and a built-in webcam and microphone, the new HP Minis are designed for consumers and business professionals who surf the web, check email, listen to music and need access to friends, family, co-workers or information.

Optical computers – photonic computer

admin — Tue, 23 Jun 2009 20:49:59 +0000

An optical computer (also called a photonic computer) is a device that uses the photons in visible light or infrared (IR) beams, rather than electric current, to perform digital computations. An electric current creates heat in computer systems, the more processing speed is needed, the more electricity is required; all this extra heat is extremely damaging to the hardware. Light however doesn’t create significant amounts of heat no matter how much is used and therefore more powerful processing systems can be produced. By applying some of the advantages of visible and/or IR networks at the device and component scale, a computer might someday be developed that can perform operations 10 or more times faster than a conventional electronic computer.
Visible-light and IR beams, unlike electric currents, pass through each other without interacting. Several (or many) laser beams can be shone so their paths intersect, but there is no interference among the beams, even when they are confined essentially to two dimensions. Electric currents must be guided around each other, and this makes three-dimensional wiring necessary. Thus, an optical computer, besides being much faster than an electronic one, might also be smaller.
Some engineers think optical computing will someday be common, but most agree that transitions will occur in specialized areas one at a time. Some optical integrated circuits have been designed and manufactured. (At least one complete, although rather large, computer has been built using optical circuits.) Three-dimensional, full-motion video can be transmitted along a bundle of fibers by breaking the image into voxels. Some optical devices can be controlled by electronic currents, even though the impulses carrying the data are visible light or IR.
Optical technology has made its most significant inroads in digital communications, where fiber optic data transmission has become commonplace. The ultimate goal is the so-called photonic network , which uses visible and IR energy exclusively between each source and destination. Optical technology is employed in CD-ROM drives and their relatives, laser printers, and most photocopiers and scanners. However, none of these devices are fully optical; all rely to some extent on conventional electronic circuits and components.
Most research projects focus on replacing current computer components with optical equivalents, resulting in an optical digital computer system processing binary data. This approach appears to offer the best short-term prospects for commercial optical computing, since optical components could be integrated into traditional computers to produce an optical/electronic hybrid. Other research projects take a non-traditional approach, attempting to develop entirely new methods of computing that are not physically possible with electronics.

Motherboard – Mainboard

admin — Tue, 23 Jun 2009 20:46:37 +0000

Motherboard
The motherboard is the “body”of the computer. Components directly attached to the motherboard include:
The central processing unit (CPU) performs most of the calculations which enable a computer to function, and is sometimes referred to as the “brain” of the computer. It is usually cooled by a heat sink and fan.
The chipset mediates communication between the CPU and the other components of the system, including main memory.
RAM Stores all running processes (applications) and the current running OS. RAM Stands for Random Access Memory
The BIOS includes boot firmware and power management. The Basic Input Output System tasks are handled by operating system drivers.
Internal Buses connect the CPU to various internal components and to expansion cards for graphics and sound.
Current
The northbridge memory controller, for RAM and PCI Express
PCI Express, for graphics cards
PCI, for other expansion cards
SATA, for disk drives
Obsolete
ATA (superseded by SATA)
AGP (superseded by PCI Express)
VLB VESA Local Bus (superseded by AGP)
ISA (expansion card slot format obsolete in PCs, but still used in industrial computers)
External Bus Controllers support ports for external peripherals. These ports may be controlled directly by the southbridge I/O controller or based on expansion cards attached to the motherboard through the PCI bus.
USB
FireWire
eSATA
