Hello guys, I don't know if anybody will see my message after a year.
Anyway, my Lenovo Ideapad is the same (Ideapad 310-15ISK) as Pob786 have, just as I live in other country, my specs are different.
It came with Intel Core i5 6200U and 4GB of RAM soldered to MB and an additional removable 4GB of RAM in second slot.
One day I realized my PC is running much slower as in the first years, then I realized, I am using only 4GB of RAM. I have never touched the removable RAM before, so I don't even have a guess what and when happened, that suddenly the removable RAM was not recognized.
I bought a new RAM, to my knowledge it should have been a compatible one, AND magic happened
. Sometimes it worked, sometimes not, also with the original RAM, when I removed it and put it back, sometimes it showed 8GB, sometimes only 4GB. However, when I was on my PC working, with 8GB of RAM, after few days it used to go into BSOD, probably because while the PC was running, something happened to the removable RAM and it disconnected. After I restarted the PC, only 4GB were recognized.
Now I resigned and I am running on 4GB of RAM which is quite painful since it is mainly eaten by chrome
.
My guess is that the motherboard is not ok and the slot is damaged. If I am right, the motherboard needs to be replaced, which is not economically feasible.
My last guess is that the updated BIOS version (latest is 0XCN45WW) could mess up with my PC, as I have read in some other forums. Now I am trying to flash older BIOS versions and I will see what happens. I could download the 0XCN44WW, 0XCN43WW and 0XCN37WW. So now I am on 0XCN44WW and it seems no magic happened
.
Other thing which irritates me is a noisy fan, which also could be connected with an updated BIOS version. I hope at least one of these problems will be solved by going back to the older BIOS version.
I remember when I was updating to the latest BIOS, however, I do not remember what was the original BIOS version and I could not find it anywhere on the internet.
