Useful suggestions to help users discussed Laptop overheating


Like any other invention, laptops also have some drawbacks and the major of them all is their heating problem. If your system shuts down suddenly then it may be an indication of overheating or it may happen due to some software failure. There is software in some laptops that shuts the system down due to excessive overheating.
This excessive over heating can cause a serious trouble either by damaging the computer as a whole or by destroying any of its very important components like motherboard, sensitive chips, graphic cards or memory cards etc. In some cases, laptops overheat because the software designed to protect the laptop specifically by controlling the operation of cooling fans, does not work properly. In other cases, this is due to the problems in the computer's BIOS, and can be cured by upgrading to the most recent BIOS.
There are well known manufacturers like Sony, Dell, HP and Acer and several others but all of the above mentioned names face the same problem with their products and that is overheating and suggestions to help users will be discussed one by one:
Other Electronics News:
Acer aspire one zg5 battery
Dell inspiron 1525 batteries
Compaq nc6400 batteries
Laptops by Hp heat up continuously even if they are three or six months old and solution can be found in monitoring your laptop temperature with free software called Speed Fan by Alnico or by getting it cleaned up as the cooling port can be clogged up with lint causing the CPU to overheat and the laptop to shut down.
Heating up in Lenovo is quite commonly observed and there comes a time when it's really impossible to work on the system if it remains open for continuous 2 - 3 hour which is due to hinges most of the time and the warranty can help as one can get it serviced by technical people over intervals because this is happening completely because of technical flaw.
Dell acknowledged this problem and designed a new fan with a better heat sink and heat pipes to provide better cooling with less noise. Any repairs made at this point will include the redesigned parts.
Spraying the keyboard with the cooling sprays can greatly reduce the temperature quickly. The temperature can fall down from 80°C to 45°C in few seconds no matter what number of applications you are running on the machine. These sprays do not have any adverse effect on the chips and the board so you can use them without any hassle.
To overcome this disastrous problem which can be a great obstacle in flow of your work, you can take few measures. It is better to operate the system at a speed which is less than the full designed speed of the hardware and software as well. Keep system at a place with cooler temperature. If you want to keep the system alive and functional for a long time then clean its parts and vents especially after dissembling it once a month at least. There are softwares available in the market which help in keeping the temperature under control and installing them can help you in the maintenance of your laptop. Notebooks should be kept on chill pads to keep them working for long hours. The machine can be saved from overheating if it is followed that prevention is better than cure.
otebooks are sophisticated piece of gadget and it comes with heavy pricing. An average laptop could cost from 600 $ to 900$ and better laptops with modern features can cost more than 2000$. When we spent this much of money over one little yet power machine, we should take care for machine too. I have seen people who update there machine once in every year, reason for this is older machines either breaks or some other problems comes up which cannot be fixable. Problems which usually encountered by users are screen breaking, breaking of joints of laptop, display problems, keyboard problems, charging issues and so many others which cannot be explained. You might find it interesting to know that some branded laptop have specific problems in their entire series of models and whoever purchase that machine sooner or later encounter with similar problems.

Five strategies help get the most out of the rechargeable batteries in Your laptops

Five strategies help get the most out of the rechargeable batteries in Your laptops - http://www.bestlaptopbattery.co.uk

Batteries are made to be used, so use them.
Just like couch potatoes, batteries need exercise. The chemicals in Lithium-Ion batteries respond best to regular recharging. So if you have a laptop, don’t keep it plugged in all the time; go ahead and let it drain to about 40 or 50 percent of capacity, and then recharge your computer.
The life of a Lithium-Ion battery can be measured in charge cycles. A charge cycle occurs when 100% of a battery’s capacity is used. Let’s say you use 50% of your laptop’s battery one day, charge it overnight, and then you use 50% of the battery again the next day. Even after charging it back up again, you’ll have only had one charge cycle occur. Most Discount hp nc6400 battery are rated for a useful life of at least 300-500 charge cycles, but high-quality, properly maintained batteries can retain up to 80% of their original life, even after 300 cycles.
Periodically calibrate your battery.
Most batteries that have a “fuel gauge”, like those in laptops, should be periodically discharged to zero. This can be accomplished simply by letting your computer run until it reports a low-battery state and suspends itself. (Do not let your computer deep discharge, as I’ll explain in the next item.)
The gauge that measures the remaining power in your laptop is based on circuitry integrated into the battery that approximates the effectiveness of the battery’s chemical compounds. Over time, a discrepancy can develop between the capacity that the internal circuitry expects the battery to have and what the Hp hstnn-ib33 Laptop Battery can actually provide. Letting your computer run down to zero every month or so can recalibrate the battery’s circuitry, and keep your computer’s estimates of its remaining life accurate.
Don’t practice so-called deep discharges.
Most laptops will suspend operation if the battery drains too low. Even if your computer goes to sleep, though, most batteries that are in good working order will still have a reserve charge available. This reserve will hold the computer’s working memory in state for a little while. A deep discharge has occurred when even that percentage of reserve power is used up. The computer will have turned off completely, and sometimes you’ll notice that it will have lost track of the correct date and time. Deep discharges will strain your batteries, so try to charge them frequently.
Avoid exposing your battery to heat (when possible).
Heat can overexcite the chemicals in your battery, shortening its overall lifespan. In fact, it’s been speculated that the biggest cause of early battery expiration is the heat that batteries can be exposed to when they’re stored in computers that are running off AC power. Laptops — especially modern multi-core machines — can get very hot when they’re plugged in, easily over 100 degrees Fahrenheit. That’s hot enough that extended exposure will negatively affect your battery. If you want to be really protective, there’s nothing saying that you can’t pop the battery out of your laptop if you’re going to be within reach of a power outlet for a while.
There may be times that you can’t help but expose your laptop battery to heat; you may live in a warm climate, for instance. You can, however, try and avoid exacerbating the issue. Make sure your laptop is well ventilated and that you’re not operating it on a surface that retains heat, even when you’re not plugged into mains power.
Store your batteries properly.
If your laptop or portable device isn’t going to be used for a while, you should remove its Lithium-Ion battery, if possible. Even if the battery can’t be separated from the device, it should be stored in a cool environment at about one-half charge. Cool temperature is recommended by experts because that can slow the natural discharge that batteries will undergo even when they’re disconnected from their device.
I’ve seen some people go even further and recommend that spare Hp dv2000 Batteries be stored in the refrigerator. I don’t think this is a very good idea; I’m concerned about condensation that might build up. Don’t put your batteries on ice, but keep them out of the sun.
Ultimately, I believe that buying spare Li-Ion batteries is a losing game, because the batteries start degrading as soon as they’re manufactured. Usually those Hp dv6000 Batteries spend most of their time sitting in a charger, losing useful life. If you need to be really mobile, you’re better off purchasing an adapter cable you can use with the power sources available in planes, trains, or autos. And, of course, by taking good care of the battery you already have.
