How do I get all the memory of my PC available in Linux ?

[sling-shot]

I have not seen the manual. I have not seen the box in question. I have not seen many boxes in general.

But of all the boxes I have seen, all have had a sticker and a warning that breaking that sticker would void warranty. And it is not possible to open the box without breaking the sticker in those boxes.

That is the practice of brand name manufacturers around here,

Read your Warranty agreement. You may have already voided it by installing third party Software, Secondary Operating System PCLinuxOS, you have all the details, read them.

Get down to the shop you bought the Box and see if they are happy to see PCLinuxOS on there ?

Actually, phone them, to save a wasted trip.

I truly think they never intended anything other than what was installed when you bought the Box, to be the Waranteed Operating System.
The Warranty will cover the OS and Hardware, I guess.
Trying not to be pessimistic, but generally a Retailer will use their corporate key, and reinstall Windows, they won't troubleshoot a problem in Linux. They'll replace a bung CD/DVD Drive, etc. If RAM shows as Good in Win 7, no problem deemed by retailer.

Best to give them a call.

How long is the Warranty ?

Once we know were we stand, ... tests can /can't be carried out.

Best of luck.

It doesn't!

Just discovered that Windows 7 and the BIOS both mention 8Gb Ram memory ....
So no discrepancy between systems and BIOS .

It appears to me that there is 8GBs of ram installed and not 16GBs as Bruno53 says.

I linked to the manual, I suggest you read it.

The manual explicitly tells the user they should maintain their PC properly ......  including cleaning the inside of the case!

Sorry that I did not read the manual.
That seems unbelievable!

I have never had a purchased PC that claimed to void the warranty if I opened the box .....  so anything else is unbelievable to me 

TBH, I fail to understand how they can guarantee the hardware without maintenance being carried out to ensure it continues to run properly.
How else can one add an extra card, or drive or correct a loose plug?
The case must be opened.

Technical specifications :

Lenovo Ideacentre B540P All-in-One PC 58,42 cm (23")
**************************************************
    Operating system: Windows 7 Home Premium 64bits
    Processor: Intel® Core™ i7-3770 Processor (8M Cache, 3.90 GHz)  -  integrated Intel HD Graphics 4000
    Memory: 16Gb (4x4Gb) DDR3 1333MHz
    Memory Slot: 4

I remember having checked the preinstalled Windows immediately after I got this computer and it then confirmed having 16Gb .

Good call Just17, and please excuse my oversight; still however I would ring the store, and talk to the manager of the Computer section.

I trust nobody in these predicaments.

What if you're 80 years old, and never taken the case of a Computer ?
They're generally tricky people to deal with, retailers, that's why I would ring first.
 
State you'd like to check the RAM as it isn't showing in Hardware Section as 16 GB's of RAM, rather 8 GB's.
See what they say.

Generally when a retailer sells a Computer, THEY want to perform the maintenance, even if: "The manual explicitly tells the user they should maintain their PC properly,..."

That could be construed as meaning taking to the qualified Maintenance section of the retailer. Who would know till you talk to the people ?

I have a throwaway HP P4 with the "Void if broken" sticker on it, which barely sticks on it's been taken off so many times, so the confusion about said sticker should be heeded, but is up to Bruno53.

Just how I see the situation, as these retail company's are pricks as far as my experience.
Once Bruno53 tells he has 8 MB of RAM showing in Device Manager, not 16MB I'd think they would say ,"Bring it in". Not, "open the case, and do what you believe is the right maintenance procedure."

Just my two cents, plus I'm totally with you Just17, your reasoning is sound as stated in the Manual.

If I bought the PC on the understanding that there was 16GB ram fitted (and not 16GB ram max) then I would certainly be ringing the store ....  and visiting them too!

Me too, it's a situation which requires checking out, Bruno53 is under warranty and should do so.

Some motherboards have a feature in their bios allowing you to enable/disable the ram channels. check to make sure all channels are enabled.
There are programs such as Everest free edition that examine the entire computer and report on all the hardware it finds. The true amount of ram in your box will be listed. You can also use CPUID to find out how much ram you actually have.
