PC Refresh service – your computer renewed

Published by:

These days a PC that is a few years old will most likely still be quite capable of useful work, but might be held-back by particular components or original specification that can be easily updated. This is especially true for work-horse systems used for web access, database or document processing – rather than high end media work or gaming systems which do generally benefit from the latest processors & technology.

An internal spring clean with battery or main drive replacement or memory boost might be all that’s required to rejuvenate your system for a few more productive years at a fraction of the cost to buy new.

ZeroTier SSH Connection problem on Windows 11

Published by:

If attempting to SSH to a remote Windows 11 system using a ZeroTier network managed address leads to a connection timeout then a possible problem is that the ZeroTier network has been configured as a PUBLIC network on the target machine, changing this to a PRIVATE network might resolve the problem. The following Powershell commands can be used.

## To check public/private setting
Get-NetConnectionProfile | Where-Object "InterfaceAlias" -like "Zero*"

## To set all ZeroTier networks to Private
Get-NetConnectionProfile | Where-Object "InterfaceAlias" -like "Zero*" | Set-NetConnectionProfile -NetworkCategory Private

Lenovo V530S Upgrading problems

Published by:

Leaving off mains will result in a the system going through a couple of reboots when next powered-up perhaps as though the CMOS settings have been lost.

When off mains the systems RTC Real Time Clock will freeze and will show the time & date in Windows when last running. The system will synchronize after another reboot but the Sync function within Windows will fail with a Time Server related error.

The original installation has a McAffee Web Advisor app installed. This might have interferred with Time synchonisation [?]

Lenovo V530S Upgrade to NVMe SSD Problem

Published by:

This small form factor machine Type 10TX0013UK. BIOS Revision M22KT49A, Block Revision level 1.49. 11/10/2022

After fitting a NVMe SSD to replace the existing hard drive the machine booted once from the cloned image but then failed with a ‘Error 1962: No operating system found’. The solution to this was to enter the BIOS and go to the Devices > Network Setup settings for PXE and disable them. This included the PXE IPV4 Network stack, same for IPV6 and the PXE option ROM setting.
