Hello all the wonderful people and welcome to our new article where we take a little different turn than usual and discuss why keeping old electronics around the house is not such a good idea. We all have some drawer or in some bag around the house and in the end of the day if that electronic has battery inside it is probably not the smart thing to keep it.

So naturally, the question comes why it is a bad idea to have old electronics with batteries in them? Well unlike a battery failure with, say, some AA batteries jammed in the back of an old toy, the risk with a lithium-ion battery failing isn’t just some leaking and corrosion in the battery compartment, it’s a potential fire as the battery swells up and the gases (combined with the stored energy) turn the battery into a potential fire hazard.

Good thing is that the battery will not explode just like that, it will swallow over time and get bigger and bigger until the breaking point is reached and all the fire breaks lose. So if by any chance you have some old gadgets lying around you can check up on them and see if has swelling process started, if yes, dispose properly of that piece of the old device immediately.

How to keep old electronics

If you’re not ready to get rid of the gadget then it’s best to charge it properly for storage. Proper charging keeps the battery cells and circuits in optimum health.

While recommendations vary by manufacturer and application, the general consensus is that lithium-ion batteries should be charged to approximately 40%. (Some manufacturers recommend charging 50% or 60% instead.)

Really, the important part here isn’t the exact percentage. What’s important is ensuring that the battery is charged to roughly half capacity and not stored with a completely discharged or completely full battery.

Discharge rates on lithium-ion batteries in completely powered-off devices are very slow, but you should still plan to top off the charge every 12-18 months or so to keep it around 50%.

If you wanted to go above and beyond, a metal storage container with a snug lid on a basement shelf with a desiccant pack inside to control the moisture would offer optimum conditions.

About Browser Hijackers

If you’ve ever downloaded software via the internet (shareware, freeware, etc,), it’s quite possible you’ve unintentionally installed unwanted programs on your PC. Potentially Unwanted Programs (PUP), also referred to as Potentially Unwanted Applications (PUA), are applications that you never wanted in the first place and often come bundled with freeware. Once installed, the majority of these applications can be tough to get rid of and become much more of an annoyance rather than a necessity. It is clear by its name – unwanted applications – but did not really constitute “malware” in the traditional sense. This is because, the majority of PUPs get into a computer not because they slip through the security holes, for instance, but because the users have got installed them themselves – 100 % unknowingly needless to say. A PUP might not be regarded as malicious or dangerous but nevertheless, it is a common reason for clunky OSs; some PUPs are a lot more aggressive by deliberately slowing down your PC.

The harm unwanted programs could do

PUPs come in various forms. Typically, they could be seen in adware bundlers that are known to use aggressive and misleading advertising. The majority of bundlers install many adware programs from a number of vendors, each of which features its own EULA policy. Safebytes Anti-Malware totally eradicates this threat and safeguards your computer against PUP or adware infection. Additionally, the majority of free programs nowadays come with a few unwanted add-ons; in most cases a web browser toolbar or browser modification such as a homepage hijacker. They can modify browser settings, change the default search engine, replace the default home page with their own websites, slow down internet speed, and also will damage your system as well. PUPs carry a dangerous bite if left unchecked. The most detrimental part of installing a PUP is the spyware, adware, and keystroke loggers that might hide inside. These are programs that don’t really do anything good for you; in addition to taking up space on your hard disk drive, they also slow down your PC, often modify settings without your authorization, the list of frustrating features goes on and on.

Tips on how to avoid getting a PUP

• When installing anything on your personal computer, always study the fine print, including the license agreement. Do not accept terms of use that are for bundled programs. • Use ONLY custom or manual install method – and never thoughtlessly click Next, Next, Next. • Use good antimalware software, such as Safebytes Anti-Malware which offers real-time protection against PUPs. • Think carefully before you download any kind of shareware or freeware. Turn off or get rid of toolbars and browser extensions you don’t actually need. • Always download applications from the original website. The majority of PUPs find their way onto your laptop or computer is via download portals, so steer clear of it entirely.

The MP4 MIME-type is a video type that is mainly configured in IIS or Internet Information console. It is the one that instructs a web browser to use the default video application when running MP4 files from websites. MIME which stands for Multipurpose Internet Mail Extensions which offers a way to identify files on the Internet-based on their format and nature. For example, when a content-type header value like MP4 is defined in an HTTP response, the browser can be configured to open the file with the proper plugin.

Error Code 0xC004F00F – What is It?

Error Code 0xC004F00F can appear during the Windows 10 installation and activation process. It is a fairly straightforward error code that occurs when a product key is entered in that is unable to be used to complete the final activation of the new operating system. This error code is most commonly related to the installation of new pieces of hardware on a machine that was already running Windows 10 at a previous time.

Error Code 0xC004F00F can also appear on other versions of the Windows software, so if you are not specifically trying to install and activate Windows 10 when this message appears, you may want to contact a qualified Windows technician to help resolve your system error, as the error code has different causes and resolution methods on other versions of the Windows operating system.

Solution

Error Causes

In some cases, Error Code 0xC004F00F will show up if you are attempting to install Windows 10 on a computer in which the hard drive has been replaced or significantly altered. It can also appear when other major pieces of hardware, like the motherboard, have been changed out.  These pieces may be changed as part of an upgrade to new or better hardware or be changed due to the malfunction of the original pieces of equipment. Because it may appear to the Windows activation servers that you are attempting to use the same product code that you have used before to activate what appears to be a new machine (even if the machine is the same one, just with some new parts), you may see Error Code 0xC004F00F arise.

Error Code 0xC004F00F can also come up if you have installed Windows 10 on your machine in the past and have already used the product key that you are attempting to use again.

Further Information and Manual Repair

Error Code 0xC004F00F most commonly appears for users who have made major hardware or software changes done on their machine. Because this error specifically arises from the Windows activation servers believing that your computer is a new one, you’ll need to get in touch with the Windows support team in order to resolve the error. From their database, they will be able to confirm that you are not using a new computer and will be able to bypass the error, allowing you to complete the Windows 10 Activation process.

If you haven’t installed or replaced any of the hardware on the computer, but are still seeing Error Code 0xC004F00F arise during your Windows 10 installation, you will still need to get in touch with the Windows support team to bypass the error code.

Calling the Windows' Support Team

When you call into the Windows support team, you’ll want to specifically have a list of the following information readily available: Which pieces of hardware have been changed out on your computer prior to the installation and activation, what method you were using to install Windows 10, which version of Windows 10 that you were attempting to install, whether it was a single-use or multiple-use license, and basic details about your PC like its make, model, and age.  You may also want to have the product key that you were attempting to use when Error Code 0xC004F00F first appeared.

By having all of this information ready and on hand ahead of time, you’ll have a greater likelihood that your error will be able to be resolved quickly and efficiently, avoiding long periods spent on the phone with customer service. Make sure that you specifically mention that you are experiencing Error Code 0xC004F00F during the Windows 10 activation process when you call into the Windows support team so that you can be connected to a representative who is equipped to help you resolve this specific problem.

Getting a Qualified Technician

If you are not comfortable in working with the Windows support team or have not been able to successfully resolve Error Code 0xC004F00F even after getting in touch with customer support, contact a qualified technician who is familiar with the Windows 10 activation process and can walk you through the things that you will need to communicate to the Windows support team in order to have them bypass or resolve the error code.

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.
