Have you ever wondered why your laptop’s fan is running loudly despite of relatively low CPU usage (like 10 to 15%)?
Or your laptop can operate on battery only for couple of hours with such low CPU usage?If so, this posting answers why it happens and tell you what you can do to improve the situation.CPU Usage number can be misleadingIn the past, most laptops were equipped with single-core single-threaded CPUs and their structure was something like Figure 1. car leather cleaner protectorWhen program runs, most components in the system turned active as shown in Figure 2 (colored components are active). cost of cleaning dryer ventsOnce it is finished, the entire system returns to idle (power saving) state. best way to clean dog pee off couchSo, the power consumed by the laptop was determined primarily by how long they become active. best deep cleaning steam vacuum
Hence, the relationship between CPU usage and power consumption was almost linear and looked like Figure 3. 1. Single CPU system configuration 2. 100% busy single CPU system 3. CPU usage vs. power consumption However, if your laptop is new, it probably has more than one CPU core and each core may support multi threading (also known as Intel Hyper-Threading Technology).professional duct cleaning cost For example, dual-core multi-threading enabled CPU is configured as shown in Figure 4.bridge home services duct cleaning Because all CPU cores/threads share the rest of the system, only one active CPU core/thread will keep most of the system active (in other words, high power consumption state) as shown in Figure 5. This means, if you are running single-threaded application and it keeps one CPU thread busy 100%, total CPU usage is still 25%, but most of the components in your laptop are active and consuming very high power already.
By increasing workload, more cores/threads will become active, but the power consumption increases only gradually because additional cores/threads are relatively small part of the system (Figure 6~8). As a result, the relationship between CPU usage and power consumption is not linear and looks like Figure 9. Power consumption increases very rapidly until the first core/thread’s usage reaches 100%. In this example, it is when total CPU use reaches 25%. If you compare Figure 2 and Figure 5, you will notice that they are very similar situations (one core or thread is running 100%). In fact, they consume similar amount of power. The only difference is, Figure 2 was called “100% CPU used”, and people accepted short battery life in the past. But, Figure 5 is now considered “only 25% CPU used” and people tend to think “CPU is not so busy, and it should not consume much power”. 4.

If most of the programs you run are (usually, most programs except for heavy games and image/video processing programs are single-threaded), you need to anticipate the CPU usage impact to the battery life can be aware that power consumption increases very rapidly as CPU usage number increases. Just a couple of percentage of CPU usage increase can easily decrease more than one hour of battery life. To maximize your laptop’s battery life, you need to carefully monitor CPU usage and make sure that unnecessary programs are not wasting CPU cycles. You can monitor program activities with standard tools like Windows Task Manager, but they only tells you current snapshot. You will not know what happened while you are not watching at the tool window. Battery Life Maximizer shows the cumulative CPU time usage by each program.
This will make it easy for you to find the program that is wasting CPU time on your laptop.References Intel: Frequently Asked Questions: Intel® Multi-Core Processor Architecture Intel: Performance Insights to Intel® Hyper-Threading Technology Filed in: TechBlog | What are your thoughts about the choice for the Department of Education, Betsy DeVos?

The portability and masses of space I save outweighs my desire for a desktop PC and separate monitor. The only thing that annoys me about my current laptop is the noise it kicks out when things start happening. This noise is my laptop cooling fan, which indicates that my laptop is hot
3 Laptop Computer Temperature Monitor Apps That Could Save Your Hard DriveIf it’s really loud then it’s too hot, and that’s not a good thing. After years of dealing with this problem, I’ve learned that there are a few things you can do to silence that cacophony on your desk and hopefully stop your laptop from falling victim to heat exhaustion. Due to their nature, size and increasing amounts of power; laptops seem to just get hotter and hotter. As a rule, my old laptops would generally go for a year without getting too hot. Now they’re so small and powerful that a laptop cooler How To Make Your Own DIY Vented Laptop Tray is pretty much a necessity from day one. If you’re thinking of gaming, editing photos and video or just leaving your laptop on for hours with 30 tabs open then a cooler is a good start. They’ll differ slightly, but generally keep to the same format of being metal (of course) slanted or flat frames with a couple of fans inside.
Your laptop sits on top of the cooler which attaches to your laptop via USB 100 Portable Apps for your USB Stick (for Mac and Win) , and just so you don’t lose that extra USB slot many even come with USB hubs built-in. They’re not ideal for on-the-go, but they’re a wise decision if you use your laptop for any great length of time at home or work. Coolers should help control your laptop’s temperature, providing you with a chilled-out PC and little-to-no fan noise. The heat generated by the CPU is generally the main heat source within a laptop, and non-vital background processes only serve to make this worse Top 5 Free Computer Maintenance Tools You Should Know About Treat your computer right and it will stay fast and responsive for many years. But neglect proper maintenance and your system will suffer. So where do you begin? With the five apps we recommend here.The processor is working overtime, generating lots of heat that a very noisy laptop cooling fan has to try and get rid of.
By killing any unwanted programs, you’re doing your processor and your ears a big favour. One solution is to kill the processes before they even start. You can manually configure what starts up in Windows using the Microsoft System Configuration Utility How To Troubleshoot Your Windows With The MSconfig UtilityHit Start, find Run (you may need to search for it, depending on your particular version of Windows) and type in msconfig and click OK. Navigate to the Startup tab and simply toggle the items you’d like to run when your computer first boots. Many update managers and system tray processes (like Quicktime, Java Update Scheduler, etc) are completely useless and simply sit there wasting your precious resources. Another solution is to use a program like Soluto Use Soluto To Improve Your Windows Boot Up Time , which analyses your boot and lets you know what action is required and what’s not required. Your laptop’s number one enemy is dust, so removing this dust not only cleans and safeguards your machine but also increases airflow which in turn will boost your fan’s efficiency.
I wouldn’t recommend doing this if you’re not 100% sure what your doing (or if it voids any warranties, naturally). You’ll need a can of compressed air (often known as computer duster), a screwdriver and patience. Turn your laptop off, remove the battery and find the screws that secure the case. Once you’ve exposed the filthy mess that is your laptop’s inner workings, set about cleaning it with the air. Preserve the air and use short sharp bursts to remove any build-up around fans, heatsinks and vents. You might want to do this outside, especially if you’ve never cleaned your laptop in this way before, as it gets pretty messy. The above video relates to cleaning a desktop PC, but the technique behind cleaning a laptop isn’t radically different. Whilst your laptop case is open, it may be worth fitting a powerful “silent” fan (though they’re never completely silent) which should keep your machine cooler and quieter. If you occasionally find yourself in situations where your laptop cooling fan must be quiet at all costs then you might want to install software that controls the speed of your fan.
By limiting the speed you can vastly reduce the noise produced, though your laptop may cook. This isn’t the best idea if you’re having cooling problems, but freeware utility SpeedFan How To Use SpeedFan to Remotely Monitor Computer Health allows you to monitor and control your fans. You can turn them right down if you need to, just don’t forget to turn them back up again afterwards. I’m not suggesting you switch your primary operating system, but for when you’re on-the-go (and away from your laptop cooler) there’s a whole load of alternatives to resource-intensive Windows. Personally I find Ubuntu Ubuntu 10.04 - An Extremely Simple Operating System [Linux] (the desktop version) runs considerably cooler on my laptop than Windows 7. This could be because I have an anti-virus The 10 Best Free Anti-Virus Programs You must know by now: you need antivirus protection. Macs, Windows and Linux PCs all need it.
