Its my last attempt to get some insights with whats going on with my laptop. I had posted in the past a question about bad perfromance of my laptop (Unreasonable laptop performance) where I was explaining the behaviour of my laptop using Windows 10 and with a the default hybrid hard disk.
Briefly, my laptop generally had a delay in typing, delay in changing browser tabs etc. (and some other effects explained in the link provided before). And this was always happening around one week from a fresh format. One week of everything performing normally and after slowly this delay was starting and going even worst etc.
I had some recommendations of checking for updates for windows 10 and some recommendation of changing the hybrid hard disk with an SSD.
And here I am now: I have upgraded to an SSD and changed Windows 10 with Ubuntu. One week of great performance and after again some of the problems: Slow typing in browser, slow typing in installed softwares, delay to enter any website, delay to close a tab(both in browser and in installed softwares).
And my questions are:
What else can it be?? ..
Does this behaviour clearly indicates that there is a hardware problem? ( as most of the same problems occurred also with ubuntu).
How can 1 week of good performance and after that bad performance can be explained?
Is there a way to measure this performance (specifically the key delay performance and the delay to load a website) in order to evalaute that there is a problem and not everything is in my mind?
And if there is not a solution how can this problem be reproduced by LENOVO technical support in order to get a replacement? (I mean if i send it to Lenovo they will probably just make a format and see that the laptop is ok, and they will just give it back to me.)
Any insight for any question would be grateful. Thank you.

Edit:
Running sudo memtester 1024 5
in one of the tests i got the following error:
Bit Flip: testing 153FAILURE: 0x00080000 != 0x00000000 at offset 0x1cd43230.
Run again the test and had a failure in:
Checkerboard: testing 44FAILURE: 0xaaaaaaaaaaa2aaaa != 0xaaaaaaaaaaaaaaaa at offset 0x05edca38.
Could it be RAM problem then?
Edit 2:
I have also noticed that this behaviour is kinda random. There are times that I open my laptop and the behaviour is pretty close to desirable and there are times that that I open it and its super delaying in typing.
Edit 3:
Tried memtest86
for whole night gave zero errors. How much sence it makes that onse i had error from memtester
and using memtest86
didnt? I have read somewhere that I one time there was error output then the RAM has problems whatever happens with next tests. Any thoughts?
If you still have Windows 10 around, may be Performance Monitor can give you some insight about what is happening: http://www.windowscentral.com/how-use-performance-monitor-windows-10
– fernando.reyes – 2017-02-20T16:51:08.447The error you get definitely suggests RAM problem. You can try to run Memtest86, it works without an OS so the test will be more comprehensive.
– gronostaj – 2017-02-20T17:13:50.890When using Ubuntu, did you reboot your Laptop regularly, or did you just hibernate it (close lid etc.)? If the latter, what happens if you reboot it completely? – dirkt – 2017-02-20T18:02:01.307
I almost never hibernate it. I remember when using windows the behavior of the laptop was really random after reboot: Some times really bad performance and other times just bad. With ubuntu seems to have similar behavior. Where this can help in indicating the problem? – Mpizos Dimitris – 2017-02-20T18:06:56.937
