How To Extend The Life Of Laptop USB Ports

Laptop’s USB ports are prone to quick damage due to over usage. A laptop has basically 2-3 three USB ports out of which one or two ports may be USB 3.0. The USB 3.0 port is extremely useful while transferring data at high speeds. The laptop’s USB ports are prone to damage because of device connection and disconnection again and again within a day. If this situation continues then the USB receptacles on laptop start to malfunction because they get loose overtime due to usage. If the port permanently fails then it needs to be changed and it is not an easy job to replace it. It is one of the costly method to get it changed also if you are submitting your laptop to your laptop manufacturer for repairing then it will take at least one week to get it repaired. So to avoid this situation we have to minimize the usage of the USB ports also you can preserve at least  one port so that it will stay alive until your laptop fails completely. I am going to tell you some tips to extend the life of the laptop USB ports.


How To Extend The Life Of Laptop USB Ports

1. No USB Hubs : Say NO to USB hubs because they use a single port to power many USB devices. This situation is like connecting many pen drives in one port. This can heat up the port and eventually it can fail.

2. Use Wireless Mouse : A wireless mouse comes with a USB nano receiver which needs to be connected to any of the USB ports of laptop. This nano receiver wirelessly receives signals from mouse. The wireless works exactly the same way as a wired mouse. After connecting the nano receiver you are actually preserving the USB port because the nano receiver can be left connected to your laptop everytime, this will prevent the connection/disconnection as you do in a wired mouse. Also the nano receiver will prevent dust from entering the port. This USB port will work until the laptop stops working.

3. Use USB Extension Cable : If you your laptop has only two USB ports then you should use a Extension cable. Just plug the cable in laptop-USB-port, now on the other end of wire you can connect/disconnect any device multiple times. This wire eliminates the wear and tear on the laptop’s USB ports and takes the damage itself. Because it is much cheaper and easy to buy a USB extension cable rather than buying and replacing a USB receptacle.


4. Cleaning : Keep the USB ports clean and remove any dust.

What Mobile Developers Have In Their Minds All The Time

The trend of mobile apps development is at the peak level. Every businessman is running to hire a creative and unique mobile app developer for their business but has anybody ever wondered what all is going through a mobile app developer for designing best quality apps which is different from all other? There are a hell lot of things that are going into a developer’s mind and they have to keep themselves updated with every new thing in their mobile world.


The job is not at all easy, though it looks very simple. Creating, designing and framing logic needs a lot of efforts and skills. Your experience and your outlook to the world and new things can only help you in designing the best. Let us have a look at what all a mobile app developer have in his/her mind that makes them in their competing spirit always.

If the mobile developer is an iOS developer and is dealing with iPhone, then Swift and the iBeacon are the two things that they must have been working with.

Swift: This new language by Apple is a big change in the working ways of iOS. The barrier towards the entry into iOS and Mac programming has gone a little high because of its objective C. Objective-C is something really of one of a kind. No developer can find an easy way as an alternate to C++ to objective C or Java to Objective C. But this new language is completely different from all these. Swift is much closer to Java therefore the programmers with Java background can enter the iOS field.

iBeacon: This was released when the new update of iOS 7 was introduced. This new Bluetooth feature offers you various possibilities for providing you proximity based content. There is something really exciting stuff that is happening with all the proximity based stuff. These devices are so fast that they are even capable of having 3D content.

Android Mobile App Developers

June 26, 2014, Google launched Android L for the developers of Nexus 5 and Nexus 7. It is believed to be working on 5,000 new APIs for a new design. Google has given a kind of different attitude in terms of its user interface and they have realized it to take more of its ownership. With Android L you can enjoy a colourful and depth based and shadow based interface and this gives us an idea that Apple seems to be going in some other direction moving more towards the flat look.

Wearable Technology : Despite of some useful efforts that Apple and Samsung have made, Google is making its way towards the wearable technology. The company has introduced a number of smartwatches at Google, though their first reviews describe them as rough drafts.
Every mobile app developer is going through something in their mind and every time they have to fight for something to make something new. The technology is evolving every now and then and there is something exciting every time to work with.

How To Play Full HD (1080p) Videos/Movies On Android

Full HD 1080p means videos or movies having a resolution of 1920x1080 pixels. This resolution is considered as Full HD (FHD) because it is intended to be played on large TV screens so that you see sharp images on a bigger screen. Most android phones have a built in feature to play HD movies because of their large screen resolution. For example Galaxy S5 can play 1080p videos in its default video player because of its large screen resolution. However other android phones doesn’t support Full HD video playback on their default media players. If you try to play the FHD movies then it will return an error. But this doesn’t mean that we can’t play 1080p videos on our android smartphones. Any android phone having a screen resolution of 854x480 that is 4 inches (the resolution depends on PPI not on screen size) can play 1080p videos, but the default media player doesn’t support FHD movies.

Watching HD movies or videos on android phone or tablet is a great fun as we can directly watch latest movies from USB pen drives on our phones if they support OTG. For OTG tutorial check this. HD movies are Dolby Digital Surround sound compatible so we can get a home theatre experience on our android phones in Full HD.

Nvidia GeForce GT 820M Notebook GPU Gaming Review

Nvidia GeForce GT  820M is an entry level gaming gpu that is found in most notebooks today. The Nvidia GeForce 820M is a notebook gpu that can be used to play any latest windows platform game till date (2013). This notebook gpu features a 28nm architecture which makes it more power efficient and delivers awesome performance at low power. In this post I will review Nvidia GeForce 820M and tell about its pros and cons, but lets start with its quick specifications.

nvidia geforce 820m

Nvidia GeForce GT  820M Specifications

  • Core Speed : 775 MHz
  • Memory : 2048 MB DDR3 VRAM
  • Memory Speed : 1800 MHz
  • Memory Bus : 64 bit
  • Shader version : 5.0
  • OpenGL : 4.4
  • OpenCL : 1.1
  • DirectX : 11.2
  • Max Resolution : 2560x1600
  • Memory Bandwidth : 14.4 GB/sec with HDMI connection
  • Max Power : 15 Watts
  • Supported Technologies : Optimus, Physx, CUDA, FXAA, Direct Compute
  • Audio : 7.1 channel HD audio on HDMI
  • GeForce Performance Score : 2.5x which means it is 2.5 times faster than Intel HD Graphics 4000.
Nvidia GeForce GT 820M Gaming Performance And Review

1. No Lags: While playing games on a Windows based pc this gpu never lags even at max resolutions. The games runs like a charm and I can’t find a single bit of lag that can destroy gameplay experience. Gaming is smooth in most games but at 1366x768 screen resolutions only. You may see lags on a bigger 720p+ displays due to its 64bit memory bus which is not enough for HD gaming. OpenGL 4.4 is a boon to this gpu because it is the latest version of OpenGL. I have played games like NFS most wanted 2012, Call of duty MW3, Grid 2 and Battlefield 3, FIFA 14, Call of Duty Black Ops at full resolutions (1366x768) without lags. Your notebook/laptop should have at least 4 GB of RAM. The gpu temperature reaches upto 40 degree Celsius in winters and upto 55 degree celcius in summers while playing games in high resolution. You can use a laptop cooler to lower down the gpu temperature by few degrees. Its gaming performance is similar to Nvidia 720M. This GPU works best with Intel Core i5 because the CPU can be overlocked so it doesn't bottleneck GPU's performance.

2. No Overheating: While playing heavy games the gpu temperature is between 40-50 degree Celsius if the notebook is new. Nvidia GPUs are on better side than AMD GPUs because AMD GPUs run hot as compared to Nvidia. So overheating is not an issue for GeForce 820M as far as notebook is new. Overtime the temperature will increase because the (TIM) thermal interface material will dry out. Its maximum temperature is around 100 degree celcius. While playing games in summer season without a notebook cooler the the temperature may rise to70 degree celsius depending on the game which you are playing. The maximum temperature of this GPU is 105 degree Celcius.

3. Nvidia Optimus : Nvidia Optimus technology automatically switches graphics between Intel HD graphics and Nvidia’s dedicated graphics. So due to optimus technology we get best all round performance while gaming.

4. GPU Boost : GPU Boost automatically overclocks the GPU chip whenever needed while gaming, if the laptop cooling system allows it. Nvidia GeForce 820M fully supports GPU Boost 2.0 which will deliver even faster and balanced performance when required.

5. Nvidia GeForce Experience:  The GeForce Experience is specially designed software for Windows that keeps the Nvidia drivers updated. It also downloads optimal game profiles for the games stored on your notebook's hard drive. It automatically optimizes PC games to deliver best performance while gaming. Download GeForce Experience

Nvidia GeForce GT 820M Vs Intel HD Graphics 4000
Intel HD Graphics 4000 is integrated graphics in Intel Core i3 processors. Nvidia GeForce 820M is 2.5 times faster and efficient than Intel HD Graphics 4000. You can check how to change between intel hd graphics and nvidia GT 820M on any laptop.

Gaming Via HDMI Cable
If you game on HDTV’s via HDMI cable then you will get best gaming graphics on a larger screen. Nvidia GeForce 820M has 2 GB dedicated DDR3 memory which is suitable for playing games on a larger HD screen via HDMI connection between your notebook and the HDTV.

No Issues With Older Games
Nvidia GeForce 820M is backward compatible with older games that are around 8 to 10 years older. I played GTA Sanandreas on this GPU without any error. However some games will give error due to incorrect resolution. So run these games in max resolution and settings. Few games require patch fix according to the windows OS you are running, but run smoothly.

Below is a gameplay video of  Call Of Duty Black Ops on Nvidia GeForce 820M at max resolution and settings.
