Computer Hardware

Generally when a file is deleted, the file system makes no effort to erase the actual data from where it is physically stored on the disk. The file system deletes files by simply breaking the file name.

In windows and DOS, the delete command simply replaces the first letter of the filename with a question mark. This indicates to the file system that the file is no longer needed and any space it occupies can now be treated as blank space, even though it isn't.

To recover the lost file, assuming no new files have been written to that space, all one needs to do is restore the file name. This can be done manually, but it is far simpler (and generally more effective) to use a file recovery utility.

If it is desired to permanently delete the data such that it cannot be recovered, the data must be over-written, preferably many times over.

Some Systems won't boot because the BIOS has been crashed or altered in some way? Try getting into the BIOS setup page by holding the escape key while booting. If you get the onscreen prompts follow them in. Check to see if the Hard drive is recognized by the BIOS, you should see a description of your Hard drive somewhere within the settings. Most BIOS have an AUTO detect function some where make sure it does. If that is all good, then you may want to have your Lap-Top boot from a Network device. Find a PC or other LT with IR (infrared connection capabilities) because your Lap-Top does (almost all do) set the good PC to share files and folders and alow access to the system files. Hopefully your LT will detect the IR port on the good PC and draw the boot info from it. You must be using the same OS on both PC's though. I have a sneaking suspicion you are using Windows 98 on a PC running 300-500 MHZ with 64-128M RAM? Windows 98 is notorious for crashing if you mess with files using software like Registry Mechanic or others.Otherwise invest in CD for your lap top and I find it hard to believe it never came with a CD or Floppy!

ide / (p)ata 133 is the speed of a Ide / (p)ata Harddrive more info @ http://en.wikipedia.org/wiki/AT_Attachment

It varies depending on clock speed, chipset.. but the maximum for it would be about 125w of power. That would be the Windsor chipset.

No. A hub is hardware that connects different devices within a single network. You probably are thinking of a switch or router.

PPPoE.

A charter bus is much more comfortable and is intended for a much more comfortable long ride with other travelers. They can be chartered, or scheduled to meet the needs of your group and are a popular means of transportation for sports teams, parties, conferences, etc.

Obviously, it doesn't have any, with the possible exception of a BIOS recovery / config jumper.

There is, but you'd have to remove the top cover.

If the laptop won't turn on try this. Remove the power cord, remove the battery. With the battery out, plug the power cord back in. Try turning the laptop on. If it comes on, then you can put the battery back in.

Network.

its powerd by the number 7

If done incorrectly, overclocking can only damage the part that you tried to overclock (resulting in a burned-out chip which will almost always require replacement) or prevent the computer from starting up (not enough power to start up the computer).

Binary system is invented to allow its use for computers where "on" is for one and "off" is for zero. So, numbers could be easily identified by the computers.

A heat sink is a device or fixture that transfers heat from a component, such as the CPU or processor, it acts like a radiator in which it transfers the heat into the air. Aluminum is shaped by the extrusion process which is like squeezing tooth paste out of a tube.

I don't know, but Toshiba Portege M300 from a box can't read it. I buy USB card reader and not use internal SD reader for years... Surprisingly, after complex update (latest BIOS, latest drivers from Toshiba site) it begin read SDHC! I glad see what my old laptop support new technology after simple software update!

Well firewire can support up to 64 and usb can support 128

It's a plastic or metal piece which holds the cooler in place, usually by screws or 'clips' onto the motherboard. It's essential for proper cooling.

It depends what you'll use it for. But overall, I'd pick HP.

The geforce 8000 series all support pixel shader 4.0 and under.

So your answer is yes.

Bad PSU, (power supply). Did not install motherboard right in case, and bad ground.

Inputs are things like the keyboard, mouse, microphone anything device that you use to input data into the computer. Output is your monitor, Speakers, any device that gives you an answer to whatever it is you input.

FireWire has a higher transfer rate than USB, making it more suitable for video transfer and connecting external storage. USB is host-based, meaningit must have a host computer to transfer data to / from (with a few exceptions). FireWire devices can transfer data between themselves directly without the need for a computer host. FireWire supports fewer devices connected together (63, vs. 127 for USB).

there really isn't anything connected to it but the motherboard, its what it dose. here is a picture of what it dose http://upload.wikimedia.org/wikipedia/commons/1/1a/Northsouthbridge.svg

Most people would consider them helpful though there are people that think we rely on them too much

There are many places to buy laptop chargers. The price range from $20 to $80 depending on where and who you buy from.

Here are a common list of websites you can search your laptop model on:

http://www.ebay.com/

http://www.amazon.com/

http://www.google.com/products

Just make sure the charger you found is specifically for Dell XPS m1530 and not a universal charger!

I would specifically recommend buying from Topmic.com because they offer lifetime warranty and free shipping to all laptop chargers at a good price. With the benefits of warranty and shipping, I think it is definitely worth it to buy chargers from them.
