I'm terribly sorry as this is the third topic about questions regarding the revival of my newly aqcuired 15" PowerBook, but I realised I better made a more general topic about it to gather all the questions I have. So I've got this 15" PowerBook (1.33 GHz, 768MB RAM, 40GB HDD) of which I recently swapped the logic board since the original one had a faulty graphics chip. Now, the laptop still has some of its original issues so I am wondering what the cause for those might be Issue #1 Whenever the PowerBook goes to sleep, be it via closing the lid or because of the power management settings, it won't wake up. The sleeping light will be blinking but I have to unplug the charger* and boot it back up; just pressing the power button (or any key at all) does not have any effect. My thoughts I've heard that a dead PRAM battery might cause troubles with power management, and since this PowerBook does not have a PRAM battery at all I think this might be the cause of this issue. I'm not sure about this, though. Issue #2 The PowerBook does have an AirPort Extreme card installed, but since my network is secured with WPA2 it won't connect with it. I do have a USB dongle which I currently use, but perhaps there would be a third-party wireless card to not lose a USB port? Issue #3 I have installed Leopard on the PowerBook. I did so because I think Tiger is too outdated and it has an odd workflow since I'm used to working with Leopard/Snow Leopard/Lion/Mountain Lion. However, the Mac is quite slow. My thoughts I was planning on upgrading the RAM to 2GB since I know that extra RAM will speed a Mac up, although I was wondering whether upgrading the HDD to a 80GB ATA/IDE drive @ 5400 RPM (currently there's the original 40GB ATA/IDE drive @ 4200 RPM) would be effective as well. If there are any other problems I might encounter with this PowerBook, I will post them in this thread to avoid polluting the PowerPC forum with my 'questions'. *the original battery is dead, so it will only run with the power adapter connected.
