How do you play DVD in compaq laptop?
Normally you slot in the DVD and it plays automatically via Windows media player or some other DVD software.
If it doesn't then you are missing something. Either.
The computer is too old and hasn't got a compatible optical unit.
Or your software is missing a player or codecs for media player.
You will need a power adaptor.
What 1GB Graphics card is better for a gaming laptop - GTX 260M or HD 4760?
Maybe Nvidia since it's more advance and more powerful than Ati graphics. But it will be expensive and Ati you can afford it and can fit in the computer. But Nvidia GTX 260m doesn't overheat that fast so it can be either one.
What types of processing devices are used in laptops?
same as in desktops and many modern mainframes and supercomputers. just lower power versions as laptops are harder to cool.
Which is the best laptop for 3d animation work and visual effect work?
I think Lenovo Essential G505s (59-380146) is one of the best laptops but there are many more laptops. like dell (inspiron 15)
HP Pavilion 15-n004TX
Will a 17.3 inch laptop fit into a backpack designed for a 17 inch laptop?
Sounds like you're asking as your thinking of purchasing it on-line. Don't! Save the hassle & go to Best Buy, Walmart, Staples, or wherever, take your 16' laptop and see if it fits. With little less than 1/2', there should not be a problem, but you never know.
Working principle of CD-drive?
Fig.1 CD-ROMs
Along with the development of information technology, many families now have their own computers at home. New personal computers are usually equipped with CD-ROM drives for multimedia uses. You must have used CD-ROMs. But do you know the working principle of CD-ROM? What are its advantages over other storage devices?
The full name of CD-ROM is Compact Disc - Read Only Memory. It is a read only information storage device. Roughly speaking, a CD-ROM consists of three layers. It has a transparent substrate as its base. On the base there is a reflective metal layer which carries information. On top of it, there is a protective coating. We know that information like sound, graphics and computer software can be digitized, that is, the data can be represented by binary numbers, which are made up of a series of '1' and '0' digits. This information is recorded on the metal layer. If we magnify the surface of the metal layer, we can see 'pits' and 'lands' in circular tracks.
We use laser beam to read the data. When the beam travels from the direction of the base and reaches the pits, the pits on the metal layer reflects the beam like a mirror. The depth of the pits is one-forth of the wavelength of the laser. The laser rays reflected by the pits and the lands have a path difference of half the wavelength (Fig. 2). It leads to destructive interference, that is, the two rays cancel each other and no reflected ray is resulted, and this produces a '1' digit. The path difference is zero for two rays both reflected by the pits, or both by the lands. No destructive interference occurs and we say it is a '0' digit. Therefore we have digit '1' at the edge of pits and digit '0' elsewhere. This is the basic mechanism of information storage and retrieval using CD-ROMs.
Fig. 2 Destructive interference occurs when laser is reflected by the edge of a pit, giving a '1' signal.
As laser beam can be focused very sharply, we can make very narrow tracks, typically in the order of wavelength of the laser, so the storage size of a CD-ROM is much larger than that of a floppy disk. We can store a lot of data like a whole movie or many softwares in a single CD-ROM, thus it speeds up the development of multimedia computers. No mechanical contact is required to read the data from a CD-ROM and it has a protective layer on it. Therefore a CD-ROM is very durable, which is one of its greatest advantages.
At present, we use semiconductor lasers, whose wavelengths are in infrared region, for reading CD-ROMs. If we use violet or even ultraviolet lasers, the tracks on CD-ROMs can be ten-folds narrower. Correspondingly, the capacity can be increased a lot. However, these products are not fully developed yet.
Where can you find free laptops?
You can't, unless legal consequences don't phase you, then I suppose you can get one however you want.
You need to find out which adapter you have. After that, check the laptop manufacture website for appropriate drivers.
Can anybody provide review about Battery Monster for hp laptop?
I purchased a battery for a dv6000 from him recently. I'm in Canada so I expected the shipping to take a bit. Couple weeks was a bit too slow but it did come and it worked fine for a week. Now it's not holding a charge BUT they do say there's a 2 year warranty on it so I've contacted them. I'll report back with the results if they agree to replace it. Might have just got a bad one so I don't want to give a bad review or anything. They were quick to ship it out at least and if they replace it without a problem I will still be a happy customer.
How can you make any website you homepage in your computer or laptop?
Just go to options and type the website under homepage (in internet explorer)

What does connector mean eletricity?
In electrical/electronics, a connector is a plug or socket. They range from a single pin to many hundreds of pins, capable of carrying many hundred amps to a few milliamps.
How long should a 4-cell 41 WHr Li-ion battery last on the HP Pavilion 15-n271sa?
About 1 hour . It depends on your usage
Is scaleing your laptop for 300 dollars with the internet to much?
Yes it's a big waste of money with 300 dollars you could buy another laptop
Will a laptop work without wifi?
If you've been in an airport, coffee shop, library or hotel recently, chances are you've been right in the middle of a wireless network. Many people also use wireless networking, also called WiFi or 802.11 networking, to connect their computers at home, and some cities are trying to use the technology to provide free or low-cost Internet access to residents. In the near future, wireless networking may become so widespread that you can access the Internet just about anywhere at any time, without using wires.
WiFi has a lot of advantages. Wireless networks are easy to set up and inexpensive. They're also unobtrusive -- unless you're on the lookout for a place to use your laptop, you may not even notice when you're in a hotspot. In this article, we'll look at the technology that allows information to travel over the air. We'll also review what it takes to create a wireless network in your home.
The computer is programmed to respond when sound cables are attached
Edit: The sound cable is being attached to the laptop, but the desktop, which is in sleep mode, wakes up. The cable is not being attached to the desktop.
How can one tell if a laptop mouse is compatible with Mac computers?
One can tell if a laptop mouse is compatible to a Mac computer by simply checking the slot of the mouse itself. If the slot of the mouse matches exactly with the slot of the Mac computer, the mouse will be compatible.
Which laptop is better dell 5521 or sony E15137CN?
This Dell model was made with many different processors and configurations. For that reason it is impossible to say which is best without knowing the exact specs of each computer. Saying all this I would not recommend either one as they are both not that reliable. The most reliable laptop is the Apple MacBook Pro. The most reliable Windows laptops are Toshiba and Acer. The MacBook Pro is far and away a superior machine albeit a little pricey. You also will not have to worry about getting a virus on a Mac if you use common sense. You can run Windows on a MacBook Pro by using the builtin program Bootcamp. So it depends on what you want to spend. If you want an inexpensive laptop the get a Toshiba or Acer. If you want the best get an Apple MacBook Pro.
There is an amazing graphics card called the ATI RADEON PRO 1600 for laptops!!! It is available for a really cheap price at pricegrabber and dont let the price fool you, its not cheap! I am running FSX (Flight Simulator X) and it requires an amazing laptop/pc. I get around 40-60 FPS (Frames Per Second) which is amazing! There is no freezing! Here is a link to the site: http://computers.pricegrabber.com/video-cards/m/16656000/ It is available for $79, which is a great deal!
A network threat is a security breach within a computer system. Examples off this is Denial-of-Service, Unauthorized Access or Confidentiality Breaches.
How you keep away your laptop from rust?
Keep it away from muriatic acid (hydrochloric acid). The acid fumes form muriatic can cause metals to rust faster. My dad has a business that uses muriatic acid for cleaning. The smoke from it, can develop rust on metals immediately on the following day. Heat produced by laptop makes rusting even faster...
You don't need to apply the acid to form rust. Using the laptop in a room with acid fumes is enough..
Connecting a double USB cable to a laptop?
A "double USB cable" is used to provide extra power to an external device, such as a hard disk in an external enclosure. It consists of two USB A-type plugs connected by a short length of cable (10-15 cm), with one of these two plugs connected by a longer cable (up to about 1 metre) to either a third USB A-type plug or a mini USB plug. You connect the "third USB A" plug or the mini USB plug to your external device enclosure and the USB A plug at the other end of the long cable to a USB port on the laptop. One USB port can provide up to 500 mA of current. If your external device needs more current, it will grind to a halt or even refuse to start moving at all. This will probably be true for bigger hard disks, CD burners and similar devices. You can then plug in the other USB A plug (the one at the and of the short cable) into an adjacent USB port on the laptop to double the amount of current available to the external device. Also seems to crop up on the Internet as a "dual input USB cable".
