It’s about 15 years, give or take, I’m working with computers and believe me yesterday was the first time I attempted to update my computer bios!

During this process, I’ve experienced some amazing stuff and I’m going to share them with you too.

My laptop is a HP G62-a22SE and I like it a lot. I do lots of things with it such as programming, listening to music, surfing the web and gaming sometimes. Yesterday, a friend of mine, suggest me to update my laptop’s bios because it will increase the computer’s performance. So I decided to update it!

I searched for “drivers and support downloads” for my laptop in HP website and found the latest bios update for it which was released in December, 2011. I downloaded and executed the bios update and after it finished, my laptop’s LCD just died!!! It took about 5-6 hours of hard working to get back to normal!!! So because it was a pain in the neck, I highly recommend keeping these tips in your mind before attempting to update your PC’s bios.

Backup your files

It’s necessary to backup your computer before start updating your bios. Also, it’s important to backup in an external drive because your hard drive won’t be accessible if anything wrong happened during update process.

Don’t execute the update app without knowledge

Bios update is not like other applications. When you run the updater, there’s no way to reinstall or uninstall it. Also, most of software updates DON’T get the confirmation for starting the update task and they start immediately after your execute the updater!

Update your PC’s bios only if it’s necessary

All in all, it’s so important to keep in mind that updating your bios is not necessary at all! If your computer is working OK, so you don’t need bios update!

Hope it helps

As you may know, I’m one of the Apple’s fans and love to use my iOS gadgets (iPhone and iPad) in every type of tasks. Many of iOS users are using their iPhones/iPads in enterprise environments and want to connect to their company’s network while at work. In some cases, network administrators set a proxy server so users must connect to that proxy in order to access internal websites and more. As you know, iOS is currently supports HTTP proxy but it’s not enough for many users because their company’s network administrators set SOCKS proxy instead of HTTP!

By the time, there are some applications that can be installed in order to use SOCKS proxy in an iOS device but these apps are only available for jailbroken devices so other users can’t install them!

In this post I want to tell you how to use SOCKS proxy in an unjailbroken iOS device.

Note: In this example I’m using an iPhone to demonstrate the steps but you can use any iOS device; there’s no limitation at all!

The first thing you need is a web server (or any computer which has access to the internet). In this example my webserver is a PC with Windows 7 ultimate installed but you can use any type of web server you want. We use this web server in order to upload a .pac file!

The .pac file

A proxy auto-config (PAC) file defines how web browsers and other user agents can automatically choose the appropriate proxy server (access method) for fetching a given URL.

A PAC file contains a JavaScript function "FindProxyForURL(url, host)". This function returns a string with one or more access method specifications. These specifications cause the user agent to use a particular proxy server or to connect directly.

For more information about PAC files Click Here

Now you need to create a PAC file like the following:

function FindProxyForURL(url, host)
{
  return "SOCKS 192.168.0.1:3128";
}

After you’ve created the PAC file, upload it to your webserver.

Finally, you have to configure your iOS device. In the Setting app, tap on the Wi-Fi and then tap on the arrow in the right side of your selected access point:

Then set HTTP proxy to “Auto” and then enter the URL of the PAC file you’ve uploaded to the webserver in the URL text box.

You’re done! Now you can access to your SOCKS proxy server!

If you have any question about this post, please leave your comments down below and I’ll answer them as soon as possible.

I really believe that HP is one of the best brands in computer industry with its great products. In fact, I’m currently using a HP G62 laptop and I’m really satisfied but one of the things that made me sad about it was the function keys.

As you know, I’m a software developer and using Visual Studio IDE. One of the most important shortcut keys in Visual Studio is F5 that complies and runs the application you’re developing. Since the function keys in HP laptops (some of models) are disabled by default, you have to hold the “fn” key and then press F5 in order to compile your application and it will bother you, I swear!

So in this post, I’m going to show you how you can disable the action keys and get back to the old-style keyboard.

There are lots of solutions over the web. Here’s an example from eHow.com:

1. Press the "Fn" and "Num Lk" keys on the keyboard simultaneously. The "Number Lock" indicator light should turn off, indicating that the letter keys will once again type letters when pressed. This combination should work on the majority of recent HP laptops. If it does not, try one of the alternate key combinations in this article's remaining steps.

2. Press the "Fn" and "F11" keys simultaneously, then attempt to type a letter. If the combination does not work, continue to the next step.

3. Press the "Fn" and "Scroll Lock" keys simultaneously, then attempt to type a letter. Continue to the next step if this does not work.

4. Press the "Fn," "Scroll Lock" and "F11" keys simultaneously.

Unfortunately, this works only in few models of HP laptops not all of them!

The Solution

• All you have to do is to go to your machine’s BIOS configuration by pressing F10 on system startup.
• In the configuration page, navigate to System Configuration tab
• And finally disable the [Action Key Mode]
• You’re done!

Now you don’t need to hold “Fn” key when want to press F keys. but if you want to let’s say turn your volume up, you need to hold the “Fn” key.

Hope it helps.
