How to fix Dell Latitude pre-boot authentication problem (Password / biometric) - Pre-boot authentication password generator / reset

You are frustrated; you turn the computer on and it gives you an error asking you to login using biometrics or to use a password, you get this error:

"This computer system,,#XXXXXXX-YYYY, is protected by a password authentication system. You Cannot Access the data on this computer without the correct password."

Then it either says: "Please type in the primary or administrator password and press Enter"
or it tells you to login / authenticate using biometric / fingerprint scanner (If it asks you to authenticate using biometric, just swipe your finger numerous times until it asks you to press enter and enter a password, then follow the steps below)

Well fear not! There are many services out there that can help you resolve this issue (Some asks you to pay money, Dell asks you to give the original owner info etc.) but the next one I'll give you is free, in case your service tag is in the compatible list.

If your service tag ends with: 595B, 2A7B, D35B, A95B, then you still have hope; follow this link: http://biospassword.eu/free/ and click on "Dell Bios/HDD" tab if it isn't already the current tab you are in, then enter your service tag in the field as asked (XXXXXXX-YYYY) where "XXXXXXX" is the number you enter as shown in the faulty computer. Click on calculate and it should give you a password down below, type that password (Case sensitive, follow the uppercase and lowercase carefully when you type) and press enter (you won't see the password being typed, just type it when it asks for you to type it or after you press enter), you should then be prompted with a menu that asks you to either press F1 or F2, press F2 and go in the BIOS settings and go to security > Password and retype the password in there but don't add a password anymore but click apply, this should remove the password and you should be able to boot the computer just fine.

These additional links might help you change your service tag if it does not belong to the list above:

How to fix JAVA garbled/broken text rendering on buttons in swing (eclipse, netbeans)

 

As you start exploring the world of Swing, JFrames, JButtons etc, it's probable that you ran into a problem where the text on your buttons and frame are all garbled up, broken, ripped, whatever else you call it.

This happens when there's a conflict between swing's rendering and your graphics card, but fear not, below are a list of fixes and you may chose what works best for you!

Fix 1 - Use a dedicated GPU with java (Semi recommended)

Open up your dedicated graphics card's control panel (in my case, NVidia), then select or add a new program, browse the following folder : "C:\Program files\java\jre1.8.0_20\bin\javaw.exe" (jre1.8.0.20 is your java version, so it depends.) then select "dedicated gpu" as preferred graphics processor.

This will solve the problem in eclipse, but sometimes not in Netbeans, so let's move on to the next solution.

Fix 2 - Disable cleartype (Not recommended)

Another temporary fix to this problem is to disable cleartype, a visual text amelioration in Windows machines, you can find this by going to your start menu and typing "Cleartype", from there, you can edit or temporarily check/uncheck the "enable cleartype" option. This will fix your problem, but then you will be left with ugly font rendering while browsing the internet and using your computer.

Fix 3 - Update your graphics card driver (Best fix)

This method is the simplest but also what I consider the "norm" fix for this problem, as it solved mine without having to always use my dedicated graphics card or disable cleartype.

You just lookup your Graphics card model, go to google and search for drivers for that one card, remember to get your drivers from official websites if possible in my case "intel HD 4000 driver", after installation, you will need to reboot your computer and then you're good to go! no more ugly text rendering.

Let me know if this hasn't fixed the problem but I hope it worked for you too.

How to take better cell phone photography

You don't always have to rely on buying the new cell phone on the market in order to take great phone photos, you just need a little bit more creativity and improve your photos everyday.

These photos were taken with the samsung captivate i897, 5mp camera.

//changelog
Alright :) so here comes the samsung captivate sample photos after it's been flashed to Android 4.2.2, CM10.1 :)Notice that the old stock froyo didn't have all these lovely options, if you're familiar with photography and SLR cameras, you'll love the new features-In camera HDR-Manual exposure-Manual focusing (including macro now)-up to 1600 ISO-Better Panorama engine.


I think that's enough words and I'll let you enjoy some sample pics.

Black background: This was taken at 4:00PM , using the sun as lighting.
The key is to isolate anything else from your key element, the main focus you want the viewer to see. Use exposure settings in your phone and black clothing to get your background right, make sure the light doesn't reflect on the cloth.

Demonstrating the use of the rule of thirds. If I've centered the image to the key element, it would probably look less good and too dull, try not to always put your main focus to the center.

Retouching is a great way to improve your photos, play around with saturations, contrast, brightness and curves, make sure not to abuse it , it will cause bad effects if so, retouching gives a more lively effect especially if your phone gives dull colors.

Play around with light and objects around your reach and learn to compose scenes, learn to use your phone's exposure settings to get you the desired lighting, in this scene, Four soda bottles were used and a 17 inch notebook, the light comes from a white page and the built in exposure functions in the phone helped give the blue tint.

Well that's all I have today folks, I hope you enjoyed the small article and don't forget to leave a comment below in case you have anything to add.

How to unbrick Samsung captivate I897 (stuck on semaphore boot logo)

If you're reading this right now it It's possible that you've got your samsung captivate bricked, or so.

Please take some time to view this thread and thank DesignGear for some info he has done:
 http://forum.xda-developers.com/showthread.php?t=731989

You should be able to fix it with this method if your problem is in the following list:

-Samsung captivate stuck on boot screen
-Samsung captivate stuck on semaphore logo

-Samsung captivate white / grey battery charging icon when plugged in.

-Samsung captivate won't make salad

In my case, I've had my captivate on CM10, a ROM failed to install (RemICS-JB v4.0) and the phone got "bricked".

Here is a picture of how it looks like:

It doesn't go anywhere, you can't go to any settings or anything, it just stays there.

"So how do I fix this?"

The first thing you need to do is to take off your sim card and your sd card, also take your battery off as it's the only way to turn off the phone. Then comes some steps.

Step 1:

Download and install the correct USB drivers for your samsung captivate if you are using windows.
Don't know how to use google? here are the links:

Windows (64 bit)
Windows (32 bit)

Step 2:

Download Odin(the One click downloader) (I897UCJF6 - Odin 3)
The links can be found here:

http://www.mediafire.com/?0w2y31maz8mdom4
http://www.multiupload.com/XAZUYNXSC1

(thanks to Designgears for the upload)

Step 3:

Enter download mode - this can be done by re-inserting the battery, plugging the phone to a cable (do not power on) and press both the  + and - buttons.

When your captivate is in download mode, it should look like this:

Step 4:

Keep your phone plugged into your computer while it's on download mode, and launch Odin

 Let it recognize your device and click on "Start"

 It should give you a bunch of all the mumble jumble you need to know if you want the details. This is the part you go to the kitchen and make coffee while waiting for it to finish.

When it's done, it should tell you "PASS!"

Your phone will reboot afterwards, then go to some sort of self configuration from the recovery mode and reboot again, it might reboot a few times but just wait for it to finish.

There you have it!
The phone should be fully working again and will be back to the old android you had.

I hope this worked for you and have a nice day sir.
