BSOD or Blue Screen of Death errors are one of the most common errors you can encounter on your Windows PC. One of these BSOD errors is the “ACPI_BIOS_ERROR”. If you suddenly get this error, it means that there is some problem in booting the operating system from your hard drive or Windows was not properly installed on your PC. In addition, this error could also mean that there is something wrong with the CMOS battery located in the motherboard. Unlike other BSOD errors, the workaround for this error is a bit different as these workarounds require a bit more expertise in updating the BIOS as well as setting the correct boot configuration. If you know are capable enough in troubleshooting the problem, refer to the instructions laid out below to fix the BSOD “ACPI_BIOS_ERROR”.

Option 1 – Try to remove the SSD and update the BIOS

The first thing you have to do is to check the primary storage devices on your PC. If you have just installed a new hard drive or SSD recently on your computer, then it’s most likely the cause of the BSOD error. Moreover, you should also ensure that your BIOS is up-to-date to the latest available build.

• Remove the SSD/HDD and inject a different HDD that was already preinstalled in your Windows PC.
• After that, update the BIOS to the latest available build. After updating it, insert the old SSD/HDD and then try to boot your PC again. The problem should be fixed now. If not, refer to the next given option.

Option 2 – Try to check the CMOS battery and reset the CMOS module

As mentioned earlier, the CMOS battery might also be the one that’s causing the problem. It is a physical component of the motherboard and is a memory chip that contains all the settings configuration on your computer and is also powered by a battery. So if your battery loses power, the CMOS will be reset and as a result, all the configurations will be gone as well. It is also possible that the CMOS module is not properly working and every time things are saved, they are properly written due to the battery. That’s why you have to consider changing the CMOS battery and see if it fixes the problem. In addition, you also have to make sure that you completely reset the CMOS module and then try booting your PC again.

Option 3 – Try to check the BIOS settings

If the BIOS settings are incorrect, chances are that’s the reason why you’re getting the “ACPI_BIOS_ERROR” BSOD error. Every BIOS has different settings which you can make use of to enhance your computer experience. So make sure that your BIOS is up-to-date and that the settings are in accordance with your requirement. Another thing you can try is to disable the Legacy USB and the Legacy BIOS in the BIOS settings if you are trying to install a 64 bit Windows version. Make sure that you also enable AHCI before plugging in the installation drive on your PC. Moreover, ensure that your PC is using IDE or Integrated Drive Electronics mode instead of SATA or Serial Advanced Technology Attachment. Aside from that, try to check the extracted setup if it is in NTFS format, if it is, you should extract the ISO in FAT32 and use it to install Windows.

Option 4 – Try to reset the ACPI Compliant Control Method

ACPI or Advanced Configuration and Power Interface provide an open standard that operating systems can use to detect hardware, perform power management, as well as monitor the status of your device and provide information for other processes. Chances are, there are some misconfigurations with this module on your PC that lead to believing that there is no battery present. That’s why you need to reset it and see if it fixes the BSOD error or not.

• Boot your PC into Safe Mode.
• Tap the Win + R keys to open the Run dialog box.
• Type in “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After opening the Device Manager, go to the “Batteries” section and click it to expand it and then right-click on the “Microsoft ACPI-Complaint Control Method Battery” option and click on Uninstall.
• After you disable the module, click on any empty space and then click the “Scan for hardware changes” option.
• Then check if you can now boot your PC normally and without the BSOD error.

After Plex, DoorDash, and LastPass, Samsung has also confirmed that they also have experienced a data breach and that some customer data has been stolen.

On Friday, September 2nd Samsung announced that an unauthorized third party gained access to some of the company's U.S. systems in late July and that Samsung learned in August that some personal information was affected. It was also stated that affected information is: names, contact information, demographics, dates of birth, and product registration information. Also so far it was said that no Social Security numbers nor credit card number information have been compromised.

For now, Samsung is sending an email directly to anyone that has been affected by this data breach, however, they did not state what service or product has experienced this breach, we just know that it has happened at Samsung Electronics America which sells everything, from smartphones to debit cards. Also keep an eye on your inbox if you are a Samsung user since it took them a whole month in order to go public with this information and there is no justification for this, if it was reported on time people could change their information and take other steps.

Scammers have decided to target Windows’s 10 App installer process in order to infect your computer and steal your data. As in most usual online scams, everything starts with a strange email containing threats and other poorly written and composed speech. At the end of the given email, there would be a link claiming that you, of course, need to read it and follow instructions about the threat, if you click the link it will open a web page where you will have an innocent-looking PDF file with more information about the threat itself. If you click on a seemingly innocent PDF file it will summon Windows 10's AppInstaller.exe tool, kickstarting a download-and-run process that'll put you in a bad place very quickly. From there, you'll have to deal with the dangers of malware BazarBackdoor, including data and credential theft. This kind of scam is nothing new but the interesting thing here is that it uses App installer and by clicking on a link you are opening and giving permission for a malicious crook to use it. So, stay safe and do not click on any links from unknown emails no matter what.

If you are trying to connect to the internet using the Microsoft Edge browser but encountered an error message instead that says, “Can’t connect to the proxy server”, read on as this post will show you how you can fix this error. This kind of error in Microsoft Edge could be caused by incorrect proxy settings or worse, malware. To fix this error, here are some suggestions you need to check out:

Option 1 – Try to check your internet connection

The first thing you can do to resolve the “Can’t connect to the proxy server” error in Microsoft Edge is to check your internet connection. There are times when your internet connection or Wi-Fi router can cause such problems. In such cases, you have to ensure that you have a valid internet source and if you are using a Wi-Fi router, you can try to use another connection and then see if the error is gone or not.

Option 2 – Try to disable the manual proxy set up from the Settings

In case you miss it, there is actually an option in the Settings panel that you can use to set up proxy in your Windows 10 computer. So if you encounter the “Can’t connect to the proxy server” error, you should disable manual proxy for the meantime and check if it fixed the error or not.
