HP Notebook PCs - System Fan (90b, 90f) Error Message on Startup
This document pertains to HP and Compaq notebook PCs.
When starting the computer, the system fan might spin faster and become louder, and one of the following error messages might display on the screen:
The system has detected that a cooling fan is not operating correctly.
Continued operation is not recommended and may cause unpredictable behavior that could result in random shutdown, data loss or possible system damage. The system will shut down in 15 seconds. To prevent shutdown and continue operation, press the Enter key now.
System Fan (90b)
System Fan (90f) This error indicates that a problem exists related to the heat removal system.
This message indicates that the system fan is not spinning at the expected speed or a problem exists related to the heat removal system. This message occurs to help prevent costly damage to the computer.
To fix this error, use the following steps:
Press Enter to clear the message and allow the system to boot to the Windows Desktop.
Shut down the computer, and then inspect and clean the exterior vents to remove dust buildup by blowing air through the vent openings. Dust can accumulate inside the vent openings and around internal cooling components, preventing the removal of heat.
After you remove the dust, turn on the computer. If the error message persists, continue with these steps.
Perform a hard reset. Performing a hard reset can reset recorded thermal values in memory and enable you to use the computer again, even if only for a short time to access and save any important files before service.
In some cases, updating the BIOS might help prevent this error from occurring.
For more information on how to update the BIOS, see Updating the BIOS.
Have the computer serviced to clean internal components and replace the system fan if necessary. Make sure to address the following items when servicing:
Thoroughly remove dust from all internal cooling components.
Make sure wires from the system and CPU fans are connected securely to the motherboard.
Confirm the system fan blades spin correctly, and the fan is not producing loud noises. If not working correctly, replace the system fan.
Remove old thermal compound from integrated circuits and heat sinks and replace with new thermal compound.
Nowadays it isn't uncommon to have more than one computer in a home, even if the owners aren't tech savvy. Transferring files between these machines is a simple process, but not everyone knows how to do it. If you or someone you know has yet to learn how to share a folder over your local network, this beginner's guide will show you how.
To see a demonstration and hear an explanation of the process for both Windows 7 and Mac OS Xv 10.6, be sure to watch the video above. The text below will help you through the rest of it.
Windows
Here's how to share a folder on your Windows machine:
Locate the folder you want to share and right click on it..
Choose "Share with..." and then select "Specific People".
A sharing panel will appear with the option to share with any users on the computer or your homegroup. You can also choose to share with "Everyone", which means the files will be accessible on your local network (basically just in your home) to anyone even if they don't have a password. This is convenient but not secure. If you want to choose this option, you can find it by click on the drop down menu towards the top of the panel.
After making your selection, click Share.
After you've clicked Share, Windows will take a moment to set up your new shared folder and it'll be accessible from other computers on your local network. To access it, simply look for your computer's name in the Network section on your other computer. When you choose it, you'll have a new option to connect to this folder.
Mac OS X
Sharing a folder on Mac OS X isn't as straightforward as it is with Windows, but it's still pretty easy to do. Here's how:
Go to the Apple menu and choose "System Preferences".
From the System Preferences panel, choose "Sharing".
On the left you'll have a few options. Towards the top should be "File Sharing", which is what you want. Click on it and make sure the box next to its name is checked off.
When the File Sharing section loads, you'll see two boxes. The left box will contain shared folders and the right box will contain the users that can access them. To add a folder, click the + sign underneath the Shared Folders box. Select the folder you want and press the Choose button.
This folder is now shared, but to the right of it you'll see what users can access this folder over the network and what they can do. For example, if you want them to be able to only read the files in the folder but not make any changes you would choose the "Read Only" option. Whatever you choose, this folder will now be shared across the local network.
To access this new shared folder from another computer, simply make a new Finder window in the Finder (by press Command + N on your keyboard or choosing "New Finder Window" from the File menu). In the bar on the left side of the window will be a section called SHARED. Beneath it will be a list of shared computers. Click on the name of the computer that has the folder you just shared and want to access. After a moment, a list of shared folders will load. Double click on the shared folder you want to access and you will be able to access it (possibly after entering your username and password, if you didn't allow access to "Everyone").

When you decide to build a PC for the first time, or the first time in a long time, you are embarking on an epic journey into the unknown. There are hundreds, even thousands, of different components to choose from, but the first and most important question you should ask yourself is a simple one: AMD or Intel?
Yes, like Apple vs Microsoft or Quake vs Unreal Tournament, AMD vs Intel is one of the great debates for PC users. One of these two companies, these two purveyors of finely-wafered silicon, will produce the beating heart of your new PC. Intel and AMD are just as different from one another as the products they produce, however, so let’s dig into the details to find out which one would be the best choice for your new PC.
Intel vs AMD: Value
With cost being such a major factor in PC building, choosing the right CPU often comes down to finding the one that offers the best bang for your buck. Just looking at price, AMD’s chips are generally cheaper than comparable Intel chips. Low-end, dual-core AMD Sempron, Athlon, or A-series dual-core processors start at about $30. In comparison, a low-end Intel chip, like the G3930 dual-core processor will cost around $40.
You’ll find similar pricing as you climb the performance ladder, with Intel’s offerings almost always coming in a little higher than AMD’s.
This is the typical scenario that most PC enthusiasts have been used to for the better part of a decade, but AMD’s new Ryzen CPUs shook up that formula when they debuted early in 2017. At the top of the consumer-focused end of AMD’s spectrum, the new Ryzen 7 1800X stands out. It’s an eight-core behemoth with a turbo-clock of 4.0 GHz, and even for $460, it’s among the least expensive eight-core processors on the market today. The Ryzen 7 1700 is even more affordable, at $300. In comparison, Intel’s most affordable octo-core costs $600.
Although not aimed at most consumers, new Intel Core i9 and AMD Threadripper CPUs offer even more performance and continue to shake up the traditional bang for buck dynamic of the processor market. Intel’s currently available i9-7900X offers 10 cores, with 20 threads, and a boosted core clock that maxes out at 4.3GHz. Its price tag is set at $1,000.
In comparison, AMD’s previewed Threadripper 1950X has 16 cores with 32 threads and a boosted core clock that reaches 4.2GHz with extended frequency range (XFR) overclocking. Its price is also $1,000. More cores at the same price gives AMD the edge in most scenarios.
What does all that mean for you? In short, it means that the age old Intel vs AMD contest is much more competitive than it’s been in years and offers much more choice for the consumer. Both companies are producing processors that are within striking distance of one another on nearly every front — price, power, and performance. Intel chips tend to offer better performance per core, but AMD is compensating with more cores at a given price.
Intel vs AMD: Gaming
Gaming is one area where picking a CPU can get tricky. AMD offers many processors which are sold as APUs, which means they combine the processor with Radeon graphics on the same chip. These offer excellent value for low-end gaming. Intel also has on-die integrated graphics, but its performance isn’t up to par with AMD’s Radeon video cards in that respect.

That said, those who take their gaming seriously don’t tend to use on integrated graphics, they use an add-in graphics card. In those scenarios, Intel tends to win out in gaming performance because of the way the two chip giants build their processors. AMD’s chips, and specifically its latest Ryzen CPUs, are excellent at multi-threaded scenarios and good at running applications that support multiple cores. Intel’s chips almost offer the reverse of that, losing out in heavy multi-threaded settings, but excelling in more restricted thread settings.
Games, although much more multi-threaded today than they were in the past, still rarely use more than two to four threads, which typically gives Intel the edge — even with Ryzen’s optimizations.
That gap is less pronounced than it used to be thanks to improvements in the new Ryzen architecture though. We saw a net loss of about 10 FPS when running Civilization VI‘s internal benchmark on the Ryzen 7 1800X, compared to the i7-7700K. The gap narrowed when running a more graphically-demanding game like For Honor, with the Ryzen CPU providing an average of 109 FPS, while the Intel Core i7 averaged 110 FPS.
As for Threadripper and Core i9 — there, too, Intel has a small edge. With that said, we wouldn’t recommend either for a gaming system. Games don’t benefit from the extremely high core counts in these processors.
Ultimately, Intel chips tend to be better for gaming of today. That doesn’t mean you should count AMD out, though. It does have processors that can be a great gaming value. The Ryzen 5 chips stand out, in particular. Check out our Ryzen processor buying guide for details, including benchmarks.
Remember, though — the CPU is rarely the limiting factor in games. Springing out for a more powerful graphics card — if you can find one at a good price — will usually yield better results than doing so for a more powerful processor.
Intel vs AMD: Overclocking
One of the first figures you might look at to compare one processor to another is its clock speed — 2.7GHz, 4.5GHz, etc. It’s a good metric to compare processors, but it’s important to keep in mind it’s not a fixed figure. Boost clocks offer temporary performance gains under specific scenarios, but if you delve into the realm of manual ‘overclocking’ you can net yourself a nice bump in performance, too.
extremeoverclock
Overclocking a processor is straightforward, depending on your chosen method, but not every processor can do it. Most CPUs ship with “locked” multipliers, which prevent users from overclocking them.
Luckily, both Intel and AMD offer unlocked CPUs at a variety of price points. If you opt for an Intel CPU, look out for those with a “K” or “X” after their name. In comparison, all of AMD’s Ryzen chips support it — though not all have full support for the automated overclocking, XFR feature.
Overclocking, in general, is very much dependent on the chips themselves . In our tests, the Ryzen 7 1800X performed well after an overclock, but we weren’t able to squeeze too much extra power out of AMD’s octo-core processor. The more mid-range 1700 and 1700X chips, however, are said to be much better overclockers.
Intel’s latest generation chips that do allow overclocking are a little more even in their potential, though their maximum is very much down to luck, as some chips can go further than others. You’ll also need decent cooling for most overclocking scenarios.
If you’re buying a chip exclusively to overclock it, then Intel’s higher-end solutions have a more established overclocking scene. Ryzen and Threadripper chips have strong potential too, though, and with a host of new memory options, may be more suited for those looking to deep dive into pushing their chip to its maximum. And you can overclock affordable AMD chips, while most affordable Intel chips don’t offer that option.
AMD vs Intel: Who wins?
During an everyday workload, a top-end AMD chip and a top-end Intel chip won’t produce radically different outcomes. There are clear distinctions in specific scenarios and benchmarks, but the CPU isn’t the keystone of PC performance that it once was.
That said, AMD’s CPUs, especially at the mid-range and lower-end of the spectrum, do tend to offer slightly better value than Intel’s. Conversely, Intel chips have stronger single core and gaming performance than even AMD’s best Threadripper CPUs. In return, those looking to use applications with a heavier multi-threaded focus, should derive more benefit from a modern AMD CPU.

When it comes to choosing your next upgrade, looking at the individual performance numbers of the chip you have your eye on is still your best bet, but considering these general guidelines will give you a good foundation of where to start. Thanks to Ryzen’s leapfrogging of previous AMD chips in terms of power and value, this is the most competitive the CPU market has been in years.
Arguably, Intel is still the safe bet, especially for gamers, but AMD’s alternatives are more viable than ever. If you’ve got deep pockets too, its Threadripper chips are incredibly powerful, so keep your eyes peeled on upcoming benchmarks.
AMD’s older FX and A-Series chips, meanwhile, are not competitive with Intel, and at this point never will be. So if you’re looking to older generations of hardware for whatever reason, our Intel recommendation is far more firm.
Microsoft's Windows OS isn't any one thing. It arises from a patchwork of finely tuned features. Each individual feature is, in turn, the result of a team of dedicated engineers who create the best (often personalizable) experience possible. So, with such a complex, nuanced, and vast piece of software, it makes sense that there are little tricks and UI flourishes that most people don't even know about.
Windows 10 Bug ArtAs it turns out, there are all sorts of tricks hidden beneath the surface of the sprawling beast that is Windows. All it takes is a little digging.
Here we present a list of 10 cool tips that will help you get a little bit more out of your Windows 10 experience. Or, at least, there are some things you may have not known about. Some have been available in Windows for a number of generations, while some are native to Microsoft's most recent OS.
PCMag has some dedicated Windows fans in our readership, so you likely know at least some of these features, but you probably don't know them all. I tested these on a pair of Lenovo laptops, one running Windows 10 and the other (when accessible) on Windows 7 Professional.
1.Secret Start Menu
If you're a fan of that old-school (i.e. non-tiled) Start menu experience, you can still have it—sorta. If you right-click on the Windows icon in the bottom-left corner, it will prompt a textual jump menu with a number of familiar popular destinations (Programs and Features, Search, Run). All these options are available through the standard menu interface, but you'll be able to access them quicker through this textual interface.
