Hi JLRR25,

 

I'm sorry to hear that you are having issues after your memory upgrade.

 

So we can check if your system can support 16GB of memory could you confirm the processor speed and also the screen size of your MacBook Pro?

 

Also can you confirm the exact part numbers of the memory you have ordered?  It will be printed on the sticker and look something like CT102864BF1339.16FE

 

Once we have this information we can look at what is causing these issues.

Hi JLRR25,

 

Thanks for the information.  If the system is picking up the memory and running then it seems to be fully detected.

 

When you say that you think the battery is draining faster, what sort of difference from the original memory are you seeing?

 

Do you know if you have all the most up to date EFI firmware updates for your Mac?

Hi JLRR25,

 

Thanks for your reply, what I would also recommend is checking that you have the correct boot order in your system.  With some Apple systems when you add or remove a new part it can change the boot priority causing the system to boot a bit slower.

 

To do this I would hold down the control key when the system is booting which will take you to disk management there will be an option to check boot settings and make sure it's set to your hard drive.

Hi,

 

I have the same problem. I can see that the battery drains faster when I am using my MacBook Pro. Also when I close the lid and the Pro goes to sleep, the battery looses too much power. A fully charged battery does not hold charge for more than 8 hrs in the sleep mode, literally the machine is dead.

 

pmset -g gives the below result

 

Active Profiles:
Battery Power 1
AC Power 2*
Currently in use:
standbydelay 4200
standby 0
womp 1
halfdim 1
hibernatefile /var/vm/sleepimage
sms 1
networkoversleep 0
disksleep 10
sleep 10
hibernatemode 3
ttyskeepawake 1
displaysleep 10
acwake 0
lidwake 1

 

I have replaced the RAM witm my old chip set and now it is all back to normal.

Any specific settings that need to be changed? I seriously feel that I am unlucky this time and received a bad kit.

Hi Naren,

 

Sorry to hear you are having problems with your upgrade.  Is this something that has always happened with it or is it just a recent issue?

Have you tried the steps mentioned above already?

 

In your reply, could you let us know your full MacBook model details, including the details of your original memory and also the full CT part number printed on the Crucial part labels?

 

Thanks

Re: MacBook Pro early 2011 - Battery issue with 16gb ram on mid-2012-mbp

[ Edited ]
in reply to Crucial_maulmod

Have there been any updates on this issue?

 

I'm having the same problem with a mid 2012 mbp.

 

Installed 16gb (CT3373648 16GB kit (8GBx2)). Battery life has signicantly dropped. Roughly from 7hrs to about 4.

The biggest problem seems to be when i put the computer to sleep and wake, this drains the battery, even if only asleep for a short time.

I'm very happy with the speed increase of the ram, has doubled the speed of many photoshop and after effects processes comared to 4gb. But obviously, battery life is hugely important for a laptop

Any advice on this?
