APC Smart UPS 3000 RM not detecting new battery pack

Problem: you replaced battery pack in your APC UPS with brand new batteries, but they are not detected by UPS unit. Failed battery LED is on, you hear alarm beeps and PowerChute console show no battery alarm.
Solution: The UPS batteries have self-discharge rate around 3% of capacity per month at 20oC (average). If you or your supplier has stored batteries for a long time, batteries may come totally discharged and UPS will not detect them. What you'll need to do in this case is to disconnect battery pack from UPS, open the battery pack cover and install one new battery into the old battery pack, connect it to UPS, let it charge for a while, then add second new battery and so on, until you fully charge all 8 batteries in the battery pack.

Xerox 116-324 fault when printing .doc or .pdf containing callibri fonts

Image
Problem : You are unable to print .PDF or .DOCX documents which contain Calibri fonts. The Xerox 7345 or similar model sends 116-324 error code and needs to reboot. Resolution : Update you computer with the latest drivers from Xerox website. If you are on PCL driver - disable the Print Optimization feature in the driver. If you are on the PS driver set the PostScript Output Option to Optimize for Portability. The print file will be larger and printing will take more time. Another PS driver setting may screw up the text in your PowerPoint slides (as shown on the picture below). It is "PostScript Pass-through". If you have printouts like on the picture below, you better enable "PostScript Pass-through" (Printing preferences> Advanced> Driver section. )

Create Outlook calendar item with Python

I've created this script when I needed to keep track of my street workout performance. I was needed to have a reminder for each day that will tell me how much repetitions I should do today. So this script will create a bunch of Microsoft Outlook appointments in your calendar according to the "table" dictionary. The table is reduced for this example. It is easier to create such table in MS Excel, then convert it to text and paste into your favourite Python IDE. Please note that this code is using PyWin32 library. def addevent(start, subject):     import win32com.client     oOutlook = win32com.client.Dispatch("Outlook.Application")     appointment = oOutlook.CreateItem(1) # 1=outlook appointment item     appointment.Start = start     appointment.Subject = subject     appointment.Duration = 20     appointment.Location = 'Sprortground'     appointment.ReminderSet = True     appo...
