How to sum a cell with another cells in different worksheets

Problem: To sum cells from another sheets in Excel

 Formulae for the example shown on picture is:
=SUM(A1;+February!A1;+March!A1)

to sum sheets named after months- in this example with cells to be summed are found at A1 address, and result to be displayed in first sheet (that's why it's called A1 - it doesn't have January in name)

If we want sum to be displayed in new sheet, the same formulae would be:
=SUM(January!A1;+February!A1;+March!A1)

or with cells we want to calculate are found at A1:
=SUM(name-of-the-first-sheet!A1+name-of-the-other-sheet!A1)

Word - removing extra page

Problem: Microsoft Word - The last (blank) page can't be removed

In this instance, blank extra page at the end of document appeared because user tried to delete last line on the first page - which didn't do anything.
The cause of annoying extra page was between cells (as showed on picture). Positioning cursor at the right spot between cells and hitting del key here removed that extra page (but also joined two tables together).

Printer Samsung ML-2851 behaving erratically

Problem were drivers on Samsung web page.

http://h30434.www3.hp.com/t5/Notebook-Lockups-Freezes-Hangs/100-CPU-Usage/td-p/200791/page/3


Quick solution is to unplug the power, to finish all instalation.
Safe mode works without interruption.

This didn't help at all:
Power options - HP Optimized selected, or if choose Power saver - it goes back to CPU 100% usage.
Options - Processor power management - lower than 100%, CPU usage still high.
Screen birightness - Windows mobility - Display Brighness - to 50%.
