Yesa, Control Center is installed. I can honestly say that I've never opened it before. I've taken a look and can't see anything that might resolve the brightness slider issue.

Thanks for the reply. No, never had to reinstall Windows.

Hi all, I have recently had the 4K display on my 5 1/2 year old Optimus 17.3" laptop replaced by PCS. Unfortunately, the brightness function key and Brightness and Colour slider in settings now no longer works properly, I'm unable to reduce from maximum. When the laptop is newly booted the Fn...

Update: For some inexplicable reason the keyboard illumination has come on. However, it does still flicker when in use. I'm now inclined to think that there is a loose connection. Before I dig out my screwdrivers and attempt a repair... are the internal keyboard connections relatively easy to...

Hi all, I bought the Optimus Series: 17.3" Matte 4K LED Widescreen (3840x2160) laptop about 5 years ago (April 2018). I've been very happy with it, there's been absolutely no problem with it, until about 3 weeks ago... The illuminated keyboard started to flicker. The Fn F4 button altered the...

Thanks for the reply. Having run through a couple of games with my son last night, it appears that different components are lacking, depending on the game being played: Minecraft is very CPU heavy, running between 95-100%. GPU at about 30%. Playing Spellbreak shows CPU 25-30%, GPU at 100%...

Hi all, My son has the desktop PC as below. He mostly plays games on it, but has recently been saying that it's generally quite "laggy". What would be the best option to improve his gaming experience? RAM is a relatively cheap upgrade. Would doubling up make much difference. Or would I need to...

Just want to post an update for anyone else that may have similar PC problems as above in the future. Apparently, the random speakers and monitor shutting off was due to a faulty motherboard, which PCS have replaced. Now awaiting delivery. Fingers crossed that all is now ok.

Update: After messaging PCS yesterday, I received an email today stating that the problem was a faulty motherboard, which has now been replaced and tested. Now awaiting email confirming dispatch.

Hi, I'm posting this here in the vague hope that someone from PCS will see it and step in. 3 weeks ago I sent a desktop back to PCS for repair: Forum Query Here The only communication I've had from them is "RMA Received" on 7th July. I called the support number on the 22nd July for an update...

Attempted to install Windows via Installation Media... No joy! Everything was installing fine, until I got to the Microsoft Login: While entering my son's Gmail address the monitors and speakers shut off. Waggling the mouse got them back, but for only a couple of seconds (not long enough for...

Many thanks UBUYSA. I'm in the process of downloading Windows Installation Media. I'll report back if this remedies the problem... or, if it doesn't. Thanks again.

Ok, test finished. I have to say... most of the results left me baffled. However, It did show 0 errors. I have a feeling that it's not actually the result I want! :(

Thanks UBUYSA, Am running the test now. I assume using default settings is the best way to go! Additional info: The monitor & speakers remain on while in BIOS, Windows downloads to reset and while running the memory test.

Just under a year ago I purchased a desktop (spec below) for my son. Over the last month or so the has developed a fault: At random times while using the PC, the monitor and connected speakers will shut off (PC remains active). Moving the mouse around will eventually turn speakers and monitor...

Hi all, Yesterday, I received a new RAM module from PCS . I turned the laptop over to begin installation and noticed 3 screws were missing :( It's no big deal, but I would like to replace those missing. Amazon sell all sorts of laptop screws. But they only describe use for the popular...

I've now tried a clean install. I still get the "The Device pages have been refreshed due to a hardware change" alert. It doesn't affect the display, as there is no user profile loaded, but does make me think that there is a problem as I wouldn't be able to load a user (Spyder) profile without...

Many thanks for your reply. The image I installed was very basic, it was created immediately after initial windows setup, It is effectively a clean install, but after all logins, accepting of Ts&Cs etc. No user installed s/w. So, was before installing Spyder. To be certain though, I'll do a...

Hi all, The display on my PCS Optimimus 17.3" has recently started playing up. Despite lots of Googling, I can't get to the bottom of it. When using the laptop, after 10 to 30 minutes the tint changes (bluer). Then after another few minutes the display reverts to the correct colour (redder)...

Now I feel stupid!!!! Thanks Bastet. I didn't even think to check the Function key - duh!! I stupidly assumed that if there's a camera it would show in Device Manager - you live and learn! Think I'd better edit my previous post about my previous PCS experience:oops: Thanks again
