Hp Compaq 6510B Review

The 14.1" HP Compaq 6510b battery notebook is one of eight or so “Balanced Mobility” business machines currently being offered by HP. The 6510b is much like the AMD based Compaq 6515b we reviewed earlier, but instead the 6510b uses the new Intel Santa Rosa platform. The 6510b has a relatively low price as it starts at $999 with a 1.80GHz Intel Core 2 Duo processor (Santa Rosa generation).





Though the 6510b is a budget business notebook, it doesn't make sacrifices when it comes to security and communications features you'd want to have as a business person. Our review model has integrated Verizon EV-DO and you can get 802.11n for faster wireless. There's a fingerprint reader for biometric security and it offers a TPM integrated security chip. The 6510b, being a business notebook, is designed so that it can share a common image with other HP notebooks if an IT department is standardizing on this brand.




The 6510b isn't made of any fancy magnesium or aluminum composite, it's mostly plastic in its build, but it's by no means flimsy because of this. It's not exactly a notebook you'd want to take along if you're a road warrior, but rather good in terms of portability between work and home where you would have a docking station at each location.




The 6510b is all business in its looks using only dark gray and black colors. It's a clean and boxy look, To keep the look clean HP even goes so far as to make the media buttons touch sensitive instead of the type that protrude. While the touch sensitive buttons look nice and the lights on them are pretty, I personally prefer the protruding buttons as it's generally more user friendly to be able to "feel" a button. Thankfully the touch sensitive buttons do not beep loudly when touched like the dv6000t buttons do, that wouldn't go over well in a business environment.




Design and Build




The build of the 6510b sony vgp-bps9 is mostly plastic. The plastic is thick though, so you still get decent protection. It's not as rugged as say a ThinkPad, but there are no major flexing issues with the chassis. The keyboard is very firm with no major flexing issues. There's a latch to hold the lid down firmly, again it is made of plastic though does its job. The hinges of the screen are just right, sturdy enough so you don't get screen wobble yet not so rigid that you can't open the screen with just one hand.




One knock is that HPincluded a plastic dummy insert for the the PCMCIA slot, a flap is preferable as those inserts are tricky and tend to get lost eventually.




The design is basic and clean. I'd call it boxy in its looks, sort of like the Honda Element of notebooks. Somehow it still looks quite trendy though, I think the fonts on the keyboard keys and cool LED lights give it a nice balance of a new age look with retro shape and styling.




The 6510b is slightly thicker and heavier than your average 14.1" business notebook, it's not as thin and light as the HP nc6400 or the ThinkPad T61 for instance.




This review notebook has a 14.1" WXGA matte screen, you can get a BrightView glossy screen of the same resolution. I prefer the matte screen for a work environment and for a business notebook. Some people that like to see greater contrast and bolder colors will go with the glossy BrightView though. The screen brightness is good, it's certainly not the brightest screen out there and not on par with a Sony or Fujitsu screen, but it's adequate. There are no complaints to be had regarding light leakage, the screen is evenly lit. As usual with notebook screens, the vertical viewing angles are not so great while the horizontal viewing angles are decent.




Sound




The sound was easily adequate on the 6510b, even good I would say. If you listen to music on a low to medium setting it's actually quite pleasant to listen to the 6510b speakers, a movie would be the same. Volume goes up to the point where it gets loud, though the sound is ear piercing at that point so you definitely won't want to use that setting. The headphone out port is on the front left side if you want better audio quality via external speakers or headphones.




Performance and Benchmarks




With the new Intel Santa Rosa Core 2 Duo processor platform on board you can rest assured performance will be at the top of the curve for notebooks. The new Intel platform was released just this May and it represents the latest and greatest. With our review unit we got a 2.20GHz processor, which is certainly speedy for a business notebook, especially one that's somewhat budget oriented. With 2 GB of RAM on board there were zero issues running Windows Vista Business and you won't get any lag. There are no dedicated graphics options, just the Intel X3100 integrated graphics solution, but that's just fine for a business machine. The Windows Vista Index score for the 6510b was very good, the lowest score was a 3.4 for graphics (which isn't bad) and the processor scored an excellent 5.1:




Battery Life




The default provided battery for the 6510b is a 6-cell battery that performed reasonably well. In battery saving mode with the screen set to middle brightness, Wi-Fi and WWAN on I got 2.5 hours of battery life. That's not half bad, dim brightness all the way down and turn off all the radios and you'll be able to push upon 3 hours of battery life.




Heat and Noise




The 6510b is fairly quiet overall, the only time I really heard any noise generated from it was when running benchmarks such as PCMark05 and 3DMark05 -- in other words, applications that really make the notebook work hard. The fan did get a bit loud during these times of intense usage, but under normal conditions you won't have any issues with too much heat or noise. I installed Notebook Hardware Control and according to its measures the CPU temperature remained at about 50C when idling. There were no hot spots on the notebook, you could easily use it in your lap comfortably and the palm rests won't make you sweat.




Wireless




The HP 6510b included the latest Intel 802.11n capable wireless chipset, the Intel 4965agn. While I didn't test the wireless with an 802.11n router, the wireless range and throughput was very good using an 802.11g router we have in our office. Wireless on/off power is managed using HP's Wireless Assistant software, or you can simply tap on the touch sensitive wireless on/off switch at the top of the keyboard. The touch sensitive button is a little finicky and I would have preferred a "real" button, even if such a thing doesn't look as fancy.




Conclusion




The HP Compaq 6510b offers a nice blend of good performance and a reasonable price. The build quality is good, but not great. The look is clean and stylish, but it won't win any awards. The screen quality is good, with no complaints, but it won't outshine some of the nicer Sony, Apple or Fujitsu displays out there. The ports selection is all you really need for a business notebook, and the keyboard is nice to use. The 6510b isn't the lightest or thinnest 14.1" screen notebook out there, but you'd be paying more if it were. In other words, HP has designed a well rounded portable notebook that's not quite on the cutting edge with any of its aspects, but it is reliable and leaves little to complain about -- exactly what you'd want in a budget business notebook.




Pros:




Solid build, pleasing design though nothing flashy
Excellent wireless connectivity options
Great performance with Intel Santa Rosa platform
Reasonable price
Good LCD
Cons:




A little bulky for a thin-and-light notebook
Plastic insert instead of a flap for PC card slot
Touch sensitive buttons are not very responsive
No pointing stick that other HP business notebooks offer

Reiki For Dummies

[simpleaffiliate source="chitika" results="0"][/simpleaffiliate]

How do I insert an HTML with a link into a PDF file so that the HTML will work and connect to the link?

Okay, so I am creating a word document that I will be putting into PDF format in Acrobat. The thing is, I have some nifty HTML links (combination of html with a link) from an affiliate program I want to use in the document so people will click on the link and it will take them to the correct website and hopefully I will get credit for what they purchase there. Example I need the following HTML link to go into my PDF doc to create and image with a link attached:

Reiki For Dummies (For Dummies (Psychology & Self Help))

How do I input this into a PDF so that it works correctly (creates the image and link)

Thanks!!!!


You don't actually need to use HTML, you can use Word's own linking ability, with your special URL.

Use the "world with a chain link" button, and for the web page name put in the URL that you would have used in your HTML. The HTML here isn't what's giving you credit, it's the link. You could also insert your image into the word doc and then use the link button to link that image.

As long as you use the right URL the method you use to 'link it', either the HTML or Word's hyperlink button, shouldn't matter.

laptops for dummies
anyone good at solving computer problems for dummies?

I've changed my password on my laptop and now I can't log in, the my "password hint" wont' work. Does anyone know how I can log in to my account? I don't have a password recovery program. (I guess I shouldn't try doing things that require baisic memory when I'm only functioning on 1 hour of sleep. Oh yeah I'm on a friend's computer )


well i would try the admin account ..reboot and start up safe mode and see if the admin account has a passowrd...instructions below.....if that does no work try the 2nd option below...but you will have to be able to burn a cd...

option 1
If Windows XP is the only operating system installed on your computer, booting into Safe Mode with these instructions.

If the computer is running, shut down Windows, and then turn off the power
Wait 30 seconds, and then turn the computer on.
Start tapping the F8 key. The Windows Advanced Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
Ensure that the Safe mode option is selected.
Press Enter. The computer then begins to start in Safe mode.
When you are finished with all troubleshooting, close all programs and restart the computer as you normally would.
To use the System Configuration Utility method

Close all open programs.
Click Start, Run and type MSCONFIG in the box and click OK
The System Configuration Utility appears, On the BOOT.INI tab, Check the "/SAFEBOOT" option, and then click OK and Restart your computer when prompted.
The computer restarts in Safe mode.
Perform the troubleshooting steps for which you are using Safe Mode.
When you are finished with troubleshooting in Safe mode, open MSCONFIG again, on the BOOT.INI tab, uncheck "/SAFEBOOT" and click OK to restart your computer


option 2

go to this link to learn how to make and use a boot disk to reset the pass

Openoffice For Dummies

[simpleaffiliate source="chitika" results="0"][/simpleaffiliate]
openoffice for dummies
Question about OpenOffice Base or SQL?

I am trying to figure out how to make a query for my table which searches only for a portion of the full name. I have a list of library books I want to categorize, and I am trying to make a query for books containing the title "Dummies" in the name, such as "Cooking for Dummies."

I tried using the query creation wizard to make the query, but I can't seem to get it to work right. I have tried using the features 'equal to, less than, greater than, etc.,' but none of them seem to work for matching a single word from a title.

Here is the SQL query file I have now:

SELECT "Library"."Title" AS "Title", "Library"."Genre" AS "Genre", "Library"."Notes" AS "Notes" FROM "Library" "Library" WHERE ( "Library"."Title" = 'Dummies' AND "Library"."Notes" = 'Unread' ) ORDER BY "Library"."Title", "Library"."Notes"

I assume the equals sign next to Dummies needs to be changed, but what do I change it to?
Thanks! The "Like '%Dummies%'" worked.


You need to use LIKE. Check out the help for whatever DB you are using on how to qualify the condition.

Most likely it is something similar to ("Library"."Title" like '%Dummies%' ...)

See Techonthenet, link below.

SQL: LIKE Condition

--------------------------------------------------------------------------------

The LIKE condition allows you to use wildcards in the where clause of an SQL statement. This allows you to perform pattern matching. The LIKE condition can be used in any valid SQL statement - select, insert, update, or delete.

The patterns that you can choose from are:

% allows you to match any string of any length (including zero length)

_ allows you to match on a single character



Examples using % wildcard

The first example that we'll take a look at involves using % in the where clause of a select statement. We are going to try to find all of the suppliers whose name begins with 'Hew'.

SELECT * FROM suppliers
WHERE supplier_name like 'Hew%';



You can also using the wildcard multiple times within the same string. For example,

SELECT * FROM suppliers
WHERE supplier_name like '%bob%';

In this example, we are looking for all suppliers whose name contains the characters 'bob'.
