There are many other scenarios where only one of those is needed: mobility or performance.Ī desktop, such as a Mac mini, can provide performance but it won't be mobile. Is the mobility of a laptop an essential part of what you're doing? For example, if the non-performant program is a game, and you travel to networked game competitions a lot, then that game is what you're doing, and mobility is essential. That is, what are you doing, and what programs are you running that are non- performant? 1.75 TB, maybe.Īlso please explain exactly what causes you to be unsatisfied with the current machine's performance. If you're referring to a disk (HD or SSD), then it's quite likely to be movable directly to a new model. If you're referring to RAM, then it's a lot larger than 1.75 Gb.
I'm not aware of any storage on your current model with 1.75 Gb capacity. Trackpad/keyboard not working - Replacing the trackpad cable may resolve this issue.As a reason for not simply buying a replacement machine, it makes no sense.Random shut downs - After ruling out obvious issues (liquid/RAM/battery), repairing the logic board resolves the issue.You must rule out liquid/bad RAM/software issues/battery, etc. This requires logic board replacement or possible repair if approved. Random shutdowns - This is caused by low voltage in one of the cores of the CPU if that core is unstable.Please rule out other issues in order to confirm.) (Note: This is not the ONLY cause for this symptom, just common. Repairing the logic board resolves the issue. Start up issue where fans spin, but display remains black and does not fully boot - This is caused by a power issue with GPU.Mid 2012 - Early 2013 MacBook Pro retina 15" A1398 Running off of one RAM stick in the good slot or replacing logic board resolves issue. LCD flickering/system freezing - This is due to defective RAM slot.You may need to reinstall the OS after replacing cable. Hard drive cable failure - You may see a very slow, yet healthy drive, CRC errors, failure to complete updates, prohibitory symbol upon start up (circle with slash), or folder with question mark.Run GPU/VST test in order to confirm.)Ģ012 MacBook Pro 13" A1278 (non-retina, with optical drive) (These are typical symptoms and not all inclusive.
