Modix HD3510: Fully Adequate DVD Player Replacement

At first glance, the white box of the Modix player looks like a normal external hard drive case. On the front is a large display and lots of function buttons, while the A/V and USB ports can be found on the back, where you can also attach an external power supply. Once you turn on the device, a menu structure will appear on the hard-to-read display. You can navigate either with the remote control or using the many buttons on the front.

The player can be controlled without a remote control, using the buttons

The remote control is pleasant to hold

Some buttons on the remote control have no functions

Player Setup: Not Much Of Use Here

Lots of setup options? Don't be fooled by its looks.

While the player's preference list contains all the absolutely critical functions, it dispenses completely with any instructions or explanations. Users are left scratching their heads over mysterious acronyms and jargon in both English and Chinese. The manual also lacks clear answers regarding what kinds of effects a modification might produce.

Setup Menu: Audio And Video

Not Many Setting Options Either

The main menu on the setup page

To get to the setup menu you have to push a button on the remote control. You'll search in vain for many menu options to configure, though. The menus are superfluously large, making it seem as if you have a lot of options to set, but you really don't.

Spartan User Menu

The main menu is frugal and dispenses with all manner of frills

The player can be unpacked and hooked up in a jiffy. Besides plugging in the small power supply, all you have to do is connect the box to a TV. The unit only functions without the PSU when it's plugged into a USB port on a computer, where it functions just as an external file storage device. The HP-25OTG likewise requires an electrical socket somewhere within a cable's reach of the power supply to work on the road.

A piece of protective plastic inside the remote prevents the battery from running down before purchase, and is easy to remove. Once you've done so, the remote control is good to go. The LED starts blinking when you turn the power switch on; the unit boots within seconds, and then a very lean main menu appears on the screen. Its four buttons take you to the respective submenus. Note that with this player, "File" describes a kind of directory structure in which you can navigate to directly select the individual files you want.

Here's How The Multimedia Player Looks Inside

The actual hardware is mounted inside the unit with four tiny screws. A small board is visible containing the 2.5" hard drive; all other components, including the decoder chip and flash memory, are located next to the drive. The back of the board is nearly devoid of components, as the player doesn't need much hardware for its decoding work.

The hard drive player uses an internal 2.5" notebook hard drive

The unit that houses the hard drive comes in a small cardboard box containing all the important accessories. The only thing missing in the standard set is a SCART adapter, which you need, however, for most TV sets you use one without a cinch input. If you opted to buy the HP-25OTG version without hard drive, you'll have to open up the unit initially to install one; the tools for doing so are included.

 

 

Compact and convenient

 

 

Where are all the buttons, you ask? There aren't any more!

BASIC INPUT OUTPUT SYSTEM

During the late s and s it became economical to move an increasing number of peripheral functions onto the motherboard see above. In the late s motherboards began to include single ICs called Super IO chips capable of supporting a set of lowspeed peripherals keyboard mouse floppy disk drive serial ports and parallel ports. As of the late s many personal computer motherboards support a full range of audio video storage and networking functions without the need for any expansion cards at all higherend systems for D gaming and computer graphics typically retain only the graphics card as a separate component.Popular personal computers such as the Apple II and IBM PC had published schematic diagrams and other documentation which permitted rapid reverseengineering and thirdparty replacement motherboards. The term mainboard is archaicly applied to devices with a single board and no additional expansions or capability. In modern terms this would include embedded systems and controlling boards in telvisions washing machines etc.


Motherboards contain some nonvolatile memory to initialize the system and load an operating system from some external peripheral device. Microcomputers such as the Apple II and IBM PC used readonly memory chips mounted in sockets on the motherboard. At power up the central processor would load its program counter with the address of the boot ROM and start executing ROM instructions displaying system information on the screen and running memory checks which would in turn start loading memory from an external or peripheral device disk drive if one isnt available then the computer can perform tasks from other memory stores or displays an error message depending on the model and design of the computer and version of the bios.

While most capacitors are rated for hours of operation at °C their expected design life roughly doubles for every °C below this. At °C a lifetime of years can be expected. This appears reasonable for a computer motherboard however many manufacturers have delivered substandard capacitorscitation needed which significantly reduce life expectancy. Inadequate case cooling and elevated temperatures easily exacerbate this problem. It is possible but tedious and timeconsuming to find and replace failed capacitors on PC motherboards it is less expensive to buy a new motherboard than to pay for such a repair.citation neededMotherboards are produced in a variety of sizes and shapes form factors some of which are specific to individual computer manufacturers. However the motherboards used in IBMcompatible commodity computers have been standardized to fit various case sizes.

Laptop computers generally use highly integrated miniaturized and customized motherboards. This is one of the reasons that laptop computers are difficult to upgrade and expensive to repair. Often the failure of one laptop component requires the replacement of the entire motherboard which is usually more expensive than a desktop motherboard due to the large number of integrated components. Almost all medium to high end Nvidia cards and most high end ATI cards support the technology.Prior to the advent of the microprocessor a computer was usually built in a cardcage case or mainframe with components connected by a backplane consisting of a set of slots themselves connected with wires in very old designs the wires were discrete connections between card connector pins but printedcircuit boards soon became the standard practice. The central processing unit memory and peripherals were housed on individual printed circuit boards which plugged into the backplane.

CENTRAL PROCESSING UNIT

Motherboards are generally air cooled with heat sinks often mounted on larger chips such as the northbridge in modern motherboards. If the motherboard is not cooled properly then this can cause the motherboard to crash. Passive cooling or a single fan mounted on the power supply was sufficient for many desktop computer CPUs until the late s since then most have required CPU fans mounted on their heatsinks due to rising clock speeds and power consumption. Most motherboards have connectors for additional case fans as well. Newer motherboards have integrated temperature sensors to detect motherboard and CPU temperatures and controllable fan connectors which the BIOS or operating system can use to regulate fan speed. Some higherpowered computers which typically have highperformance processors and large amounts of RAM as well as highperformance video cards use a watercooling system instead of many fans.

Some small form factor computers and home theater PCs designed for quiet and energyefficient operation boast fanless designs. This typically requires the use of a lowpower CPU as well as careful layout of the motherboard and other components to allow for heat sink placement.A study found that some spurious computer crashes and general reliability issues ranging from screen image distortions to IO readwrite errors can be attributed not to software or peripheral hardware but to aging capacitors on PC motherboards. Ultimately this was shown to be the result of a faulty electrolyte formulation. For more information on premature capacitor failure on PC motherboards see capacitor plague.Motherboards use electrolytic capacitors to filter the DC power distributed around the board. These capacitors age at a temperaturedependent rate as their water based electrolytes slowly evaporate. This can lead to loss of capacitance and subsequent motherboard malfunctions due to voltage instabilities.

Motherboard

A motherboard is the central printed circuit board PCB in some complex electronic systems such as modern personal computers. The motherboard is sometimes alternatively known as the mainboard system board or on Apple computers the logic board. It is also sometimes casually shortened to moboMost computer motherboards produced today are designed for IBMcompatible computers which currently account for around of global PC salescitation needed. A motherboard like a backplane provides the electrical connections by which the other components of the system communicate but unlike a backplane it also hosts the central processing unit and other subsystems and devicesMotherboards are also used in many other electronics devices.A typical desktop computer has its microprocessor main memory and other essential components on the motherboard.

Other components such as external storage controllers for video display and sound and peripheral devices may be attached to the motherboard as plugin cards or via cables although in modern computers it is increasingly common to integrate some of these peripherals into the motherboard itself.An important component of a motherboard is the microprocessors supporting chipset which provides the supporting interfaces between the CPU and the various buses and external components. This chipset determines to an extent the features and capabilities of the motherboard.Additionally nearly all motherboards include logic and connectors to support commonlyused input devices such as PS connectors for a mouse and keyboard. Early personal computers such as the Apple II or IBM PC included only this minimal peripheral support on the motherboard.
