Laptops are great companions for people who wish to carry out their work on the move, and even for people who like to watch movies and listen to music when they are moving around. The small size of laptops make them very portable and easy to carry around, but the fact is that this size causes the manufacturers to compromise on certain aspects of the machine.
One such area of laptops that almost everyone is unhappy with, is the sound system on these machines. The speakers are placed inside the machine, but in most cases the quality of these speakers is just average. This leads many people to attach external speakers to their laptops, and this inadvertently also leads to a greater amount of problems for the user.
Laptop Sound Not Working
Laptop sound problems can be attributed either to a faulty sound card, or to a defect in the speakers of the machine itself. If you are facing sound problems with external speakers attached, then the problem probably lies with these speakers and their drivers. There are plenty of solutions to all of these issues, so you must not get disheartened. The very first thing that you must do is check the volume settings of the machine. You may have accidentally reduced the volume or even muted the speakers, so you need to ensure that this is not the case. Once you have checked the volume settings on the machine, you can proceed to other solutions if you are still not getting any sound from the machine.
The next step that you can take is reinstall the sound drivers on your machine. For this purpose you will need to visit your laptop manufacturers website, locate the Support section and then locate the latest sound drivers for your particular model. Once you locate them you will need to install them on your machine, but not before you uninstall your previous set of sound drivers. Drivers are a group of programs that ensure that a particular piece of hardware attached to your machine works properly. In case you are using external speakers then you can reinstall the sound drivers for the set by unplugging the speakers and plugging it back in again, or by inserting a CD or DVD if it has been provided with the speakers.
One method to be sure that the problem is with the laptop speaker itself is to plug in a pair of headphones or earphones and then check the quality of the audio output. If the problem in the sound still persists then the issue is with your sound card, but if the sound comes out fine then the problem is with your internal laptop speakers. If you still find your laptop speakers not working even after reinstalling the sound drivers, then you need to take the laptop to a computer repair store and have them look for the possible problem. This may take some time and cost you some money to fix, but it will be an effective solution.
In some situations the problem may occur only when one attaches a set of headphones, earphones or external speakers to the machine. If the sound comes out fine without any of these peripherals, then the problem probably lies in the headphone jack of your laptop. This is a very rare occurrence, but it is a very real possibility. If this is the case, then the only solution for you is to take your laptop to a repair store.
Laptops are not easy to manage since there are so many electrical components that are found inside. Each and every one of them is susceptible to damage from time to time, and it is very hard to predict when a certain component will stop working. If you are experiencing laptop sound problems there are only a handful of reasons that could be the cause, and pinpointing these causes is not a difficult task.
Even if we know it’s a bad idea, we will drink and work on the laptop whenever the two things coincide. It is also, unfortunately, in our nature to be clumsy the moment we let our guard down and spill the drink on the laptop. The consequent panic is also natural, sadly. Here is a list of things that you need to know and do if in case your laptop suffers a spill-on.
Steps to Clean and Save Your Laptop
Shutting Down
Regardless of the drink you spill, the first thing you need to do is shut your laptop down. I would prefer a cold stop, which is pressing the power key till the laptop shuts down. After that, remove the laptop battery and A/C adapter attached to your laptop. If you have any external devices or other cables attached to your laptop, take them out before you move around. If we spill a drink on the laptop, we will naturally panic and do something unnecessary. Don’t get tangled in the wires when you’re getting up, you’ll just add to the damage.
Draining the Liquid
After you’re sure the laptop is switched off and the battery and all the devices are disconnected, turn your laptop upside down. Most laptops now come with spill-proof keyboards so the liquid should just flow out of the keyboard. Bear in mind, ‘spill-proof’ means the liquid won’t reach the internal components, and even that’s not a guarantee. Depending on the liquid, your laptop will suffer damage to the keys and internal components.
If the liquid is something like water, you won’t have to face too much damage. Just keep the laptop inverted for as long as possible (at least 6 hours), after which you can use something that can absorb water to wipe the keyboard clean, like paper towels or Q-tips, as long as it won’t deposit lint into the keys.
If the liquid is not water, there will be damage according to two things the liquid can be. If it’s sticky like soda, it will corrode the keys and internal components over time. If it’s hot like coffee, it will seep inside the laptop, instantly damaging the laptop. Your first steps would still be to shut down the laptop and invert it.
Wiping the Liquids
If you spilled water, your laptop should be fine. All you need to do is drain the water out, wipe the keys on the inside with a water absorbent material that doesn’t leave lint. Leave the laptop alone for at least 24 hours to completely dry out (6 hours to drain the water and 18 hours to dry the laptop). Do not turn your laptop on before 24 hours, even if it is important. Remember that electronics and water do not go hand in hand, so you need to be sure all the water has dried off.
If you have spilled soda or juice or coffee on your laptop, you need to do more work as these liquids will do some real damage. First, you will drain out the liquid from the laptop. Do not keep it there for too long. You need to clean the sticky liquid off before it dries out too much. The best stuff that you can use for cleaning is denatured alcohol. The denatured alcohol makes sure all the liquid is cleaned off. Any sticky liquid that remains on the keys or the components will slowly corrode the surface, wearing down your laptop.
Dos and Don’ts
There are some tricks that you can use, to dry out your laptop faster and some mistakes that you need to avoid.
- One trick that works is to drain off the liquid from the laptop quickly, take a bag full of rice and stick the laptop in the bag. The rice will absorb all the liquid that seeps out of the laptop, making sure your laptop dries out as fast as possible.
- When you dry out your laptop, don’t use a hair-dryer. The heat from the hair-dryer will destroy your laptop in two ways; it will fry some components, leaving them useless; it will only encourage the liquid to heat up and dig deeper into the surface, speeding up the corrosion.
- The best way to dry out the laptop is place it in indirect heat or slightly away from a direct heat source. The best spot is on a table or window sill just out of the sunlight’s reach. If the laptop comes in direct contact with a heat source, it may melt some parts or make the liquid burrow deeper into the surface.
- Make sure, whatever you use to clean the laptop (including your fingers) is lint free and static electricity free. You may not feel the shock, but the parts of the laptop surely can.
Prevention is the best cure, they say. Don’t drink anything around your laptop if you don’t want to fry it up. If nothing works, you best go over to a professional and hope your laptop isn’t dead.
It is becoming increasingly common for laptops to have HDMI ports embedded in them nowadays, and this is simply because more and more people now own HDTV sets and more and more video content is being digitalized in the 1080p full-HDMI output. HDMI stands for High Definition Multimedia Interface, and this is simply a way of expressing the high quality content that is transferred through an HDMI connection.
High Definition TV sets are common consumer electronics today, and almost every household owns one today. These TV sets are made full use of when HD content is played on them, and the picture quality that is offered is so sharp and crisp that it looks like real life images. 1080p output is the standard for the best HD content today, and the ‘p’ here stand for Progressive. This is simply a way of expressing how the pixels in the 1080 vertical lines of the TV screen color up via the light source, and produce a supremely clear image for the viewer.
Laptops With HDMI Output
A lot of this HD content is obtained by people on their laptops. This is achieved either through streaming content online, buying content online or simply downloading it online. There are some laptop models that are capable of producing 1080p HD content, but their small screen size limits the viewing experience. If you are like me, then you will want to view this HD content on your big screen TV, and this is possible only on laptops with HDMI output. This enables a connection between a laptop and an HDTV set, thus enabling you to watch the HD content at ease. Needless to say, you need to know how to connect laptop to HDTV before you undertake this viewing process.
Most of the major laptop manufacturers now offer their new machines with HDMI ports embedded in them because they have realized the needs of buyers. It will increase the attractiveness and the utility of their laptops if they have an HDMI port, and this is also influenced by the popularity of HDTV sets in the market. Moreover, HD output is also becoming very common today, with a lot of smartphones also capable of recording HD videos.
HDMI port for the purpose of establishing a connection with an HDTV set. This function is vital for modern day laptops since almost everyone has an HDTV, as mentioned earlier. The ability to see HD output on one’s laptop itself is an added benefit that many people would willingly pay a premium for. This HD content can even be viewed through the optical drive, which would be capable of playing Blu-Ray discs. If you have recorded HD content through an HD camera or a smartphone, then this video output would also be supported on these laptops. A high quality video card with a minimum of 256MB memory is also incorporated into these machines to be able to generate this HD content.
As time passes and technology progresses, HD content will become even more widespread and even more intense in detail.
