What is the wattage of my HP computer?

Have a look at this site "www.crucial.com/uk". Use the "System Scanner" towards the bottom of the page left side, next to Memory Advisor this will scan your pc and will then tell you what memory you require.
Hope this helps.

Power Supply - 200 Watts

That is the supposed Maximum Wattage the computer will use per hour.

Variables come in to play, however;

1) Back when the computer was made, the Power Supply manufacturers were 'fudging' the real maximum rated Wattage.

True ratings were more like 60 to 70 percent, of what was actually stated.

Divide 200 by ten; take it times;
6 for 60 percent. 120 Watts
7 for 70 percent. 140 Watts

So, the Actual Maximum Rate Wattage, could be as little as 120 Watts, or a little more than a 100 Watt light bulb.

2) Second variable is what is the computer being used for?
Surfing the internet? About 100 Watts.

Playing an intensive game, (Yeah right. Not on that computer), or using an intensive program?
Then, you may be using the Maximum rated Wattage,
120 to 140 Watts.

So,........the hourly wattage rating, could be as low as 100 Watts per hour, or perhaps up to 120 to 140 watts per hour.

Also include the power used by the monitor.
If you do not have the specifications of the monitor, see if you can look them up online.

My HP 2009M uses 47 Watts, (2 Watts when in Sleep Mode),

My other monitor I use (Dual monitors), is an RCA 26 inch HDTV,
(RCA L26HD31)

Uses 82 Watts,

(And the power supply for my computer is 500 Watts.
Hmmm,............no wonder the little wheel spins so fast in my electric meter! lol!)

Add the two together to get a basic conclusion, of what Wattage per Hour your computer system is using.
Don't forget to include printer/scanner/fax machine/copier, WHEN being used.

1) Click Start.
2) Click Run (or for Vista/Windows 7.. click in the search box..)
3) Type 'Devmgmt.msc'
4) Search for any devices that have exclamation marks next to them. If you find any, right click on them and choose 'Uninstall'.
5) Restart computer and let it reinstall sound drivers for you.

If this doesn't work then begin this solution:

1) Visit www.hp.com
2) Top right search bar, type your product number.
3) It will bring up your computer/model... click Downloads/Drivers (or Software/Drivers.. something like that)
4) Scroll through the options to choose Audio Drivers
5) Download the latest version, install.. should fix it.

Good luck!

You need to go to www.hp.com and enter the computer model. Then check the block that says you want drivers. It will take you to the driver site.

One of larger wattage won't hurt at all. If you put one in of lower wattage you might find yourself without enough power.

Product Key always comes with the product package....if you need to use the genuine product of vendor you will need to buy the original version of software/program that you want to use. and With the package/disk you will get the key to unlock or register or open the product with full of it's features...

Thanks for joining fixya...

Have a nice day.

As long as your sound card is compatible with Vista, the speakers should work.
