are computer power supplies interchangeable
mamarose854 Transformer blew in the neighborhood and now no power to my Inspiron 530s. I also have a Dimension E510. DC power is simply electricity that only has the ability to flow in one direction. However, the wall outlets which supply power to a laptop and charge its batteries all run on alternating current, or AC power. AC power varies at a consistent rate, resulting in a positively charged current. Connection. The final feature to consider when looking for a laptop power adapter is the connection to the computer itself. Many different brands of computers such as Dell, HP, and Acer use laptop power adapters with the same or similar voltage and output power needs. Universal laptop power adapters are only available as an aftermarket purchase; they are generally much more expensive than either replacement AC adapters or DC adapters. The purpose of a universal power adapter is to accommodate all types of laptops and charging situations through the use of interchangeable tips. The power supply consists on several wires that connect to specific parts of the compute … r. Examples are the IDE/SATA CD/DVD Drive, IDE/SATA Hard Disk Drive, the motherboard, etc. Power supplies are only a computer part in a desktop computer, NOT a laptop computer. The different types of laptop power adapters on the market serve to help convert the power provided by plugs into the power needed to operate a laptop computer. The amperage rating isn't sufficient (as noted) and it isn't necessarily the same polarity either. You can possibly check if there is a polarity diagram on the adapters. In general, laptop power supplies are not interchangeable. So probably safe and unlikely to catch fire is about the best advice you'll get. posted by chairface at 4:47 PM on December 20, 2007. Thanks; I think I'll just wait and get a new replacement adapter tomorrow-just to be safe. The power supply in a PC is a complex device using switch mode circuitry and transformers to generate +and- 12v, for modems and communications ports. +and-5volts for the … logic circuitry,3volts for the processor. All these supplies are generated and electronically regulated. Output Power. The output power of a laptop is measured in amps (A) or milliamps (mA). This number refers to the current output that the adapter needs to function; it makes sure that the laptop receives the power that it needs to function normally and that it gets that power in a steady stream. posted by JeffL to Computers & Internet (9 answers total) 1 user marked this as a favorite. The power supply for my Toshiba Satellite laptop just got fried-there was a kink in the cord which finally caused a wire to fray, and now the thing is dead.
