Is the power supply to your laptop not right? You may not know always beforehand that it is faulty or failing, but there are definitely some signs that will indicate that your laptop power supply is faulty.

1. Frequent crashes and instability:

Watch the signs when your laptop crashes. Does it crash when hard or optical drives start back up during booting up or when you load a game with a detailed sequence? These activities need more power supply and when it causes crashing, and then your power supply might be faulty. Also, be aware of random reboots and lockups that cause instability in the machine as they may also be due to a faulty power supply.

2. Strange noises/odour or smoke:

Are you hearing strange noises in your laptop? Check from where these noises emit, if it is close to the area of the power supply, then it may be faulty. Also, check for signs of the sound of the fan. Is it too loud or very quiet? That might also be an indicator of a faulty power supply. Sometimes the wires inside the power supply cord can burn and can emit a strange odour like a smell of chemicals or something burning. In some instances, if smoke emits out of the power supply, then it needs to be replaced immediately before something extreme like bursting or blow out happens.

3. Nothing happens when you switch on the computer,:

When nothing happens when you switch on the computer, then it may be a power supply problem. Because even if a laptop is broken, when the power supply is good, there will be some indication it is turning on like the fan running, or the LED indicator turning up. But if it remains dead when everything is alright, then it will be a power supply fault. Get it checked with a technical professional.

4. Laptop turns off automatically or battery won’t charge:

Everything seems to be operating right, but all of a sudden if your laptop frequently switches off or if the battery does not charge even after removing it and putting it back, then the power supply needs to be checked. When the power supply area is hotter than usual or if it emits wrong voltage than required, the laptop will turn off frequently or it might switch on for a few seconds before going blank.

5. Intermittent display of blue screen of death:

Are you constantly seeing an intermittent display of the Blue Screen of Death (BSoD) on your laptop? It is usually due to a critical error and sometimes due to software crashes or faulty hardware. But when all seems fine, it may be due to a faulty power supply. The laptop power supply can be faulty sometimes when you don’t use the right charger for your laptop. Try not to buy ‘Universal’ power adapters as they may not suit all models. Also, as soon as you suspect a fault in your power supply replace them as soon as possible, as a delay might lead to bigger laptop failures
laptop-951954_960_720The world has become so dependent on technology that everything seems to be done online. Be it payment of bills or playing online games on a gaming laptop. It could also be simple reading on the kindle app. Housewives these days too seem to spend a lot of time for various reasons ranging from research work for children’s school projects or catching up on television serials that they might have missed. While the ‘work’ computer has its own features needed to suit organizational rules, the home computer is usually for fun. So basically it all boils down to how we use these devices today more than anything else. Here are a few things to consider when buying a laptop for home use.

Laptop weight

Home use laptops tend to be mobile and are carried around from room to room. So an ideal laptop would be a machine that is fairly weightless and easy to carry around the house. A slim design seems perfect for easy portability both within the residence or for a quick trip to the coffee shop close by.


Typically home use laptops are used to watch movies, videos, etc. There is also a tendency to download videos music and movies on the home laptop, hence storage is critical. Of course, one can also make do with limited storage if there is an external storage device available for backup. The adequate number of ports will be a factor to consider. Not just for USB but also speakers if needed. Most laptops are manufactured with a hard drive with between 250 GB and 1 TB.


DVD and CD players come inbuilt in all laptops. It plays an important role in the life of a housewife who wants to catch up with the latest movies but might not want to download them from the net. For gamers, a gaming laptop is a solid, although slightly more expensive choice. Make sure you do your research and you can often find a great deal for less than 1000 dollars.

Processor speed

A high-end processor is not the need of the day when it comes to laptops for home use. Nothing can feel worse than a slow system, though. So a dual-core processor, which enables efficient operation of multiple windows, would be preferable.

Screen size

To ensure the ability to watch a movie with ease and not have  put pressure on the eyes, a screen as big as 14 inches would be ideal.

Screen protector

This is to ensure that the eyes do not get strained while reading or watching movies. Many laptops come with an anti-glare display.

Adequate ports

Be it for some solitary time with headphones or family fun with an external speaker, there is always need for multiple ports in a laptop. So too is the case with USB ports. It’s always useful to have 2 or 3, so you can plug in a mouse and a pen drive at the same time.


Wireless network is an essential part of the laptop. If a modem is not available at any point due to power shortage, a port is needed to attach a mobile internet connection such as 4g. Bluetooth can also be used to transfer files from the laptop to a mobile phone and vice versa.


No matter if you want an affordable gaming laptop or just a lightweight laptop for watching movies, now you know what you need to look for in the hunt for the perfect laptop for you. Enjoy finding the perfect laptop.
The graphic card is an essential component of PC and laptop, as it provides better display and picture output. It is a plug-in device that enhances the available display features. It connects to the motherboard via PCI/AGP slots. Without adding an external graphic card, the system would utilize the inbuilt video display drivers for display optimization.

Purpose of Graphic cards

The basic and primary function of a graphics card is to obtain video information from laptop processor and convert them into electronic signals. The monitor, in turn, receives them and decodes it into quality pictures that can be displayed. The minimum configuration of graphic card required for any laptop is usually built into the motherboard. However, this can provide just the basic display features. The graphic cards come with their own set of memory called VRAM. The card utilizes this for handling video information. This reduces the utilization of laptop’s RAM and hence enables the machine to perform faster.

Adding graphics card to your laptop

The chances of requiring a graphic card upgrade for your laptop is pretty slim these days. The reason is obvious. The majority of today’s laptops come equipped with GPU [Graphical processing Unit]. The GPU is attached to the laptop motherboard, so upgrading a graphic card would mean replacing the entire motherboard. It’s as good as buying a new laptop. The viable alternative would be to include external graphic card through the USB port. However, this cannot be used for gaming purposes which require extreme quality graphics. By plugging in an external graphic card through USB port, one can make use of either built in screen or an external display like monitor or HDMI.

Brand dependency

The possibility to upgrade the graphic card in a laptop also depends on the brand and model of the laptop in question. Certain laptop models provide the updating option. However, majority of laptop devices in the market are NOT upgradable.

Specification Benchmarks

Since it is not always possible to update the graphic card once the laptop is purchased, one must exercise caution in selecting the proper GPU configuration while deciding on the laptop. The specifications required would depend on four deciding factors. They are:
  1. RAM of the laptop
  2. Required video clarity
  3. Nebus Graphics cardGaming requirements
  4. 3D viewing necessities
The most important specifications to look for are:
  • Supported resolution
  • Video card memory
  • Refresh rate in your favorite game with the graphic card

The actual upgrade

When the situation permits, if you can upgrade the graphic card of your laptop, here are the guiding steps to assist with the physical upgrade. First and foremost ensure that the new graphic card is provided by the laptop vendor or at least declared compatible with the laptop model. As per specifications mentioned, few BIOS level settings needs to be changed. Once BIOS settings are completed, the laptop can be unplugged and switched off. The next step would be the removal of the battery. Now, the four screws guarding the drive must be removed to gain access to the graphic card slot. Finally, slide the edge of new graphics card and push it into its slot. Replace the battery, screws and power on your laptop.
