VMWare Player keeps autoinstalling Visual C++ redistributables even when they have been uninstalled and the computer is without network

21 December 2024 @ 1:44 pm

I am preparing a document about installing VMWare Player. I did the installation once, and I remember the installer asking if it can download the necessary Visual C++ redistributables from the network. Now, I want to do install it again to test if I can point the user to do manual redistributable installation first, to make it possible to install stuff offline. However now I have a problem. Whatever I do, reinstalling the VMWare player automatically pulls the redistributables from somewhere. Affected software I have uninstalled redistributables and VMWare Player, rebooted the machine, removed everything relevant in disk cleanup, and it still finds from somewhere the redistributables. I tried even without network and Windows was still able to automatically find the redistributables. How do I remove the redistributables co

Lenovo 20e3 computer boots but the UEFI is a total mess. Any Idea on how to fix this one?

21 December 2024 @ 1:26 pm

I've been playing with a Lenovo 20e3 for a while now, and I ended up breaking the UEFI at some unknown point in the past 8 months or so? To be honest I don't remember what I was doing at that time, but I think I was playing with mint or something... The computer boot fine, but I can no longer acces the UEFI menu and the output of efibootmgr is now super wierd. I'd like to fix it a little just so I can finally change the settings in the UEFI again as some of them aren't very friendly to my KDE neon install. This neon istall is curently the only OS on the system, also the computer original came with some customized version of Windows 8.1 if this is of any help. I don't have access to a recovery disk as Lenovo in pure Lenovo fashion dropped all support for this machine. Here's the output of efibootmgr: BootCurrent: 000B Timeout: 2 seconds BootOrder: 000B,0009,000A,0000,0005,0004,

Monitor's refresh rate drops to 60hz when certain windows are focused

21 December 2024 @ 12:57 pm

In windows display settings or intel graphics command center, the refresh rate of my monitor is set to 120hz. However, when certain application's window get focus, the entire screen's refresh rate drops to 60hz, which is noticeable by mouse cursor moves. I know that there is an issue with Windows Presentation Foundation (https://github.com/dotnet/wpf/issues/2294), and my monitor is Variable Refresh Rate capable, but I have disabled that in intel graphics command center. Also, the issue occurs when all the applications are minimized and only the background wallpaper is being shown. When certain "modern" application windows is un-minimized, the refresh rate goes up to 120hz again. When a Firefox browser windows is focused, and the browser is displaying mostly static contents, the refresh rate drops to 60hz; When some animation kicks in in the webpage, the refresh rate goes

SCSI, IDE, SATA on PCI cards (chipsets) for booting from ODD with largest x86* MB/OS coverage

21 December 2024 @ 12:34 pm

I would like to have 1...3 PCI cards that could connect my optical disk (CD or DVD-ROM) drive to a variety of mainboards (x86 machines, including servers) so that I could boot from the inserted disk. What cards/models matches this the best, please? System firmware (BIOS or UEFI) of the mainboards would support booting Optional ROMs from such add-in PCI cards. My drive would be connected via SCSI / IDE (PATA) / SATA bus. I would like to cover a very wide range of commodity operating systems too: Windows (from 3.1 and NT 3.1 to w11) Linux (from 2.0...2.2 through 2.4...2.6 to the current 6.x) FreeBSD and NetBSD preferably the illumOS kernel too I mean that OS should have an built-in, integrated driver (that works out of the box). Early versions of Windows supported both SCSI and cheaper IDE (PATA) buses. The latest versions seem to have trouble with running drivers for at least some SCSI car

What is the pinout for the 9-pin connector on a 97Wh Dell laptop battery?

21 December 2024 @ 12:18 pm

I'm working with a 97Wh battery from a Dell laptop, and I'm trying to understand the pinout of its 9-pin connector for troubleshooting and possible repairs. I know the pins are used for power, communication, and monitoring the battery's status, but I need more specific details on the exact pin configuration. Could someone provide the pinout for the 9-pin connector on this type of Dell laptop battery, including which pins correspond to positive (VBAT), ground (GND), temperature sensor, SMBus communication, and other functions?

BSOD on connecting laptop to projector. PC won't boot now and no HDD/SDD shown in BIOS

21 December 2024 @ 8:19 am

Problem: So my Toshiba laptop ran into a BSOD (I didn't note the error msg) the moment I connected it to a working projector screen using an HDMI I think. I disconnected the projector but now on boot it says: Checking media presence. No media present And on pressing a key: Reboot and select proper Boot device or Insert Boot Media in selected Boot device and press a key Some context: This was the first time I connected it to a projector. And the BSOD and boot issue never happened before. (It did boot successfully randomly once but then ran into a BSOD again.) Note that in the BIOS: No HDD or SDD are present No boot manager is showing Highest priority is HDD/SDD UEFI is chosen I don't see any PXE related terms Finally, the laptop has an SSD and HDD. Both have always worked. Wind

5 beeps for 5 times when boot computer with no display [closed]

21 December 2024 @ 8:18 am

I have an Intel Core i5 but it is not booting up, there's no display on the monitor. I actually took the ram sticks off the slots and didn't put them back properly. But now, I have installed them. Changed the ram slots of each other. Tried installing only one ram stick in each slot. Nothing worked bruh. I don't have a graphics card and only have 2 rams slots and the ram sticks are 4 GB each. I ran it very easily before,I played many games on it but from that day when I unplugged the ram sticks and didn't install them properly it keeps doing the same.

Folder robocopied from a portable USB drive to a laptop PC hard disk unaccountably becomes system+hidden

21 December 2024 @ 4:36 am

I just copied many files from a portable disk to a new laptop PC using robocopy /MIR in a cmd window, under Windows 11. It all seemed to go well; I can open files and folders under C:\X\, e.g. in C:\X\A\, C:\X\B\, etc., which I take as proof that 'something' has been copied and the folder exists. However, folder 'X' is not displayed in File Explorer, nor is it listed by dir C:\. Path This PC \ Acer(C:) \ X appears on top of the File Explorer window, and I see all folders under 'X', but then when I navigate a level up, and path This PC \ Acer(C:) is displayed on top, 'X' is not listed... How can this be explained? As per previous post title, I thought that the folder was not hidden; I did not do anything to make it hidden, and when I selected the option to show hidden objects, some semi-transparent folders appeared in C:, but not that o
