For a new battery, we advise that you update the BIOS of your laptop, and open the hardware automatic identification port of your laptop. When you use it firstly, you need to full discharge till the laptop shut off, then charge it about 11 hours. Usually, new battery need to fully discharge and charge for three or four times, which can achieve the best performance. About the new battery, please set the power management of your laptop: Property -> Screen Saver -> power -> Power scheme -> Portable / Laptop -> please cancel about low battery alarm and serious shortage of battery alarm when use the battery. You could try to take out the battery from your laptop, and put it back again, repeat several times. Make sure that it isn't a poor contact problem between the battery and your laptop. If the battery works in higher temperature, the battery protection plate will work and the laptop restart program will make a termination order. You can take out the battery, put it back again, and avoid work in high temperature. In order to avoid some damage to the battery, please note: Please don't take out the battery when the laptop is in run status. Please don't pull out the ac adapter frequently when the battery is charging. Please use high quality and reliable Dell Studio 1745 laptop ac adapter, not to use the universal laptop charger. Avoid the positive and negative short circuit. There is an overcharge and over discharge protection device inside the battery, so short-circuit may cause the battery damage. Is there the battery problem if the new battery cann't charge? That's not usually the case. When equipment for the first time to recharge the battery, the instability of the voltage and current may cause the battery charge to 50% (sometimes more, sometimes less), and equipment stop charging the battery. If this happens,don't worry. You just remove the battey from the equipment, recharge again. First charging a new battery may need several repeated process. Please be assured that this is normal.
Hope it can help you.
I recently installed apple updates 4 days ago. Since then I have issues with the headphone jack working on and off and now its my charging point. My macbook is out of warranty but in vgc and not used alot. Could there be something dodgy in the updates that has prompted this?? since my macbookpro has not been exposed to any new conditions and this just seems so odd. Im not sure what to do but read something online that it is possible to send an undetectable bug to the laptop so you have to purchase replacement/ additional hardware. Does anyone know about this or can help what the issue might be. I have never had this kind of issue with a immaculately maintained machine just going on the blink out of the blue shortly after accepting these updates. Please help!! I need this to finish a project that is all set up on apple software that I am on a deadline for !! I already tried 1) reset SMC and 2) a different charger but none of these do anything...very frustrated!
