Adding 4Gb of memory to my HP Stream Mini had an unexpected effect and I'm wondering what anyone else can recommend to fix the issue. After running the machine for a day or so, adding the software I needed, I ended up with about 5Gb of space free. I left the machine running updates overnight and it must have hibernated. The resulting space left on the machine was about 128Mb. Looks like the hibernation file which is set to 75% of RAM expanded to about 4.5Gb and filled up all the space. I thought Win 8.1 didn't use hibernation, and the option is unchecked in settings, but clearly its still creating the file. Anyone else come across this? Any advice on how to get back some space?
I'm no expert but I think 8.1 includes a hiberfil not only for hibernation but also as part of the fast-boot procedure. If you don't need hibernation you can delete hiberfil but you then probably have a slower boot. Alternatively I think you can reduce the % of ram figure but I'm not sure by how much. Also note that 6GB of ram probably results in an increase in the pagefile size so maybe you need to reduce that as well. Search for optimization of SSD's etc.
However, although HP calls this a desktop PC, I suggest you need to remember it's a ''mini'' desktop and it's not built to load up with stuff in the same way you cannot load up a mini car with as much stuff as a truck. So whether or not you have enough space on the SSD depends on how many updates to Win and other M$ programs and on how much other software you install/download. I have 6GB of ram and when I installed Office 2007 and set windows update to automatically download/install all important and recommended upgrades then, like you, I immediately ran out of space on the SSD.
So I re-set to factory settings; updated Windows Defender as anti-virus; set Windows Update to download/install only important updates and only for Windows. With all the current 8.1 important updates installed; hiberfil at 4.8GB and pagefile at 0.5GB my SSD used space is 13.3GB and free space is 8.3GB. I think I could probably re-install Office 2007 and still have free space if I refused to install the Office updates but I'm OK using portable LibreOffice and I have that and all the other software I need from portableapps on a 16GB SD card. However all that software comes to only about 1.5Gb so would easily fit on the SSD free space. So it's a ''mini'' desktop and I've found I use it as such. If I want to use it for heavy duty stuff then I'd need to upgrade the 32GB SSD.
