Hi guys,
My Macbook Pro laptop started to shutdown randomly when I have been
running my laptop off battery power. I've done some searching for a
resolution to this issue on some websites and it appears to be a
common problem with both Macbook and Macbook Pro laptops - http://
www.macbookrandomshutdown.com/.
My (relevant) system information.
Macbook Pro 15", 2.16 GHz Intel Core Duo, 1G 667 MHz RAM
Mac OSX 10.4.10
Production year: 2006
Production week: 23 (June)
Battery Information:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 4748
Remaining Capacity (mAh): 4237
Amperage (mA): -1693
Voltage (mV): 11418
Cycle Count: 267
I've attempted to resolve / troubleshoot this problem by:
- Running a Apple Hardware Test - no hardware issues identified
- Did a PMU reset but this did not resolve the issue
- Update latest software updates - Identified there was a firmware
for Macbooks to resolve this issue but there isn't a similar update
for Macbook Pro - http://www.apple.com/support/downloads/
macbooksmcfirmwareupdate11.html
- Thought it might have been a Battery issue as officially reported
by Apple but I have not encountered their prescribed symptoms -
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
I've looked at some other websites and other people have resolved
this issue by:
- Replacing the heat sink - http://maba.wordpress.com/2006/09/01/
macbook-shutdown-solved-at-last-hopefully/
- Replacing the logic board
- Replacing the battery
- and other possible solutions suggested at http://
www.macbookrandomshutdown.com/.
I guess I will call Apple Centre tomorrow and attempt to resolve this
but I'm currently in the situation where I can't really be without my
laptop for more than a day so the only viable option at the moment
would be to get the battery replaced.
I was wondering if anybody else has experienced / resolved this issue?
Cheers,
Kevin
