I had some odd issues at first with it apparently 'not booting' (nothing but a black screen), but after three tries it did work. I noticed there wasn't any battery in it (still isn't) and, obviously, it only worked when I plugged it in to the power supply, so I didn't think too much of this 'not booting'.Now after I've installed Windows, restarted a couple of times, did some updates and I didn't notice the problem again so I thought it was fixed. But then I unplugged it, put it away for two days and the problem is 'back', it was probably never gone. So I decided to open the laptop, clean some of the components, plug them in and out. All to no avail, still the same problem. It will only boot 'properly' after a couple of boots, not the same number, seems just random.I believe I've found the source of the issue which is either the RAM in combination with the video card or the video card by itself. I think so because the laptop does seem to boot (I know because there's different shutdown behavior after some time, for instance I start it and then immediately press shut down, it won't do anything, but if I start it, wait a minute and then press shutdown it will shut down (which probably means I ended up at the login screen, which would explain this behavior)), but I just can't see it.Now: if I get it to work, shut it down, leave it plugged and boot it again an hour later, there are no problems at all, but if I get it to work, shut it down, unplug it and boot it again a minute later, it won't work and I'll have to try 3-10 times to get it 'booting' again.There was also some odd stuff going on with the fan, but I don't think it's related as the behavior of the fan and the display didn't match (sometimes the fan would work, but the display wouldn't or the display would work and the fan wouldn't or they would both not work or they would both work, so no pattern. Also I cleaned it by removing it from the case and well, cleaning it and now it seems to work 9/10 times, rather than 1/4 times before).Any ideas?(Updating the BIOS and updating the integrated videocards firmware are next on my list, but I don't think the BIOS update will do any good as there are no similar problems mentioned in the changelog and I'm not able to find a firmware update...)
