is it possible to upgrade a macbook pro 15 late 2008 memory upgrade to 8 go

Hi from Belgium,

Is it possible to upgrade a macbook pro 15 late 2008 memory from 4 to 8 go. And if yes would i have to replace both memory modules.

I'm also experiencing problems with the battery. Could you tell me if the new replacement batteries are based on the new techonology (long lasting) or if the replacement battery will be the same as the original one.

Thanks and have a good day.

According to this article, upgrade up to 6GB is possible. 4 plus 2

Thanks dominic23 it really helps.

Has someone an idea concerning the battery replacement.

I'm also experiencing problems with the battery. Could you tell me if the new replacement batteries are based on the new techonology (quick charge & long lasting) or if the replacement battery will be the same as the original one.

Thanks

The Mactracker database show 8GB is possible:

as does Other World Computing:

We are not Apple employees but, based on experience around here, a replacement battery will not have upgraded technology over the one your now have.

Can you expand on the battery issues? You can show us your battery condiditon by pressing and holding the OPTION key while clicking on your Apple menu. The first item, normally "About this Mac," will change to "System Information" -- launch it.

When the SI window comes up, select "Power" from the left-hand navigation pane to get something like this:

Please copy the lines starting with "Charge information" through "Voltage (mV)" and paste here.

Hi CMCSK and thanks.

Maybe it's because of the SMC reset I've done.

My computer wasn't responding to the power button when pressed and used to shut down unexpectedly so I did the SMC reset as per the procedure hereafter.

So according to you, the battery seems to work properly and doesn't need to be replaced.

Don't know if it's important but the figures I gave where the one with magsafe connected.

In fact for the time beeing I only use my computer with magsafe plugged.

I just unplugged the magpower and here are the new figures after 10 minutes.

Charge Information:

Charge Remaining (mAh): 3103

Fully Charged: No

Charging: No

Full Charge Capacity (mAh): 3491

Health Information:

Cycle Count: 245

Condition: Normal

Battery Installed: Yes

Amperage (mA): -1431

Voltage (mV): 11816

Are these figures still ok ? Thanks for your help and have a good day.

Appears to be ok. When was the last time you calibrated your Macbook Pro? Read the user manual that came with your computer for the calibration schedule.

Thanks CMCSK.

Actually I have never done any battery calibration and didn't know I should have done it until you told me in your mail.

I will do a calibration tomorrow (it's almost 01:00 am here in belgium).

Thanks to you CMCSK, to dominic23 and to Allan Jones for your precious help.

I can see Apple Support Communities are like Apple products ... very efficient.

Have a good night or a good day.

Thanks. 🙂
