Whats wrong? Do i need new battery or adapter? Please help me guys, i don't wanna spent my bucks for new notebook now. Thanks in advance.

Is there a X on the battery icon ? How many charge cycles is on the battery? The macbook won't power up without the MagSafe plugged in . If your Mackbook is still under warranty then go for replacement.

The removable batteries in most notebooks are designed to be replaced. You use them for a year or two, then get a new one. It’s a process in which lots of batteries are used up and discarded. Because the battery in the new MacBook Pro lasts up to five years, it uses just one battery in the same time a typical notebook uses three. And to help ensure that batteries are disposed of in an environmentally responsible way, Apple offers a battery take-back program in 95 percent of the countries in which it does business.

The battery in the new MacBook Pro notebooks is made to be smart. It’s built with a chip that talks to each of its cells to determine their precise condition. The chip shares this information with the computer. And the computer uses an advanced algorithm to make delicate adjustments to the charging current, varying it to suit the changing conditions inside the cells. This Adaptive Charging reduces the wear and tear on the battery and gives it a much longer lifespan than ever before — up to five years.2

But charging is only part of the story. The battery innovations in the new MacBook Pro go deeper — into the very chemical makeup of the battery. Apple’s team of scientists and electro-chemists developed advanced chemistry that extends the battery’s lifespan even further.

The lifespan of a battery is measured in recharges. One recharge is a complete charge and discharge of a battery’s energy. A recharge doesn’t necessarily occur every time you plug in your notebook; many partial charges can add up to a single full recharge. The typical battery delivers about 200 to 300 recharges before its capacity declines to approximately 80 percent. At that point the battery still works, but its performance is diminished. Thanks to the breakthroughs of advanced chemistry and Adaptive Charging, the battery in the 13-, 15-, and 17-inch MacBook Pro can go through up to 1000 recharges before it reaches 80 percent of its original capacity — nearly three times the lifespan of typical notebook batteries

Try by Resetting the System Management Controller (SMC).

The System Management Controller is an integrated circuit (computer chip) that is on the logic board of the computer. As the name implies, it is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

Over time, the settings in the System Management Controller may become unusable, which can result in operational anomalies with the computer. Examples include not turning on, not waking from sleep, not charging the battery, or not recognizing the AC Adapter, among others.

Resetting the SMC is not intended for resolution of a stall or situation in which the computer is unresponsive. An SMC reset should not be necessary except as a last resort in cases where a hardware issue with the power management system is suspected. Performing an SMC reset resets the hardware power management functions.


MacBook Pro (Late 2008 and later)

1. If the computer is on, turn it off by choosing Shutdown from the Apple () menu.
2. Connect the power adapter to a working power source.
3. On the built-in keyboard, press (left) Shift-Control-Option along with the power button once.
4. Wait 5 seconds and press the power button to start the computer.

Note: You must use the keys on the left side of the built-in keyboard.

You should only perform an SMC reset when the MacBook Air or MacBook Pro (17-inch, Early 2009) has been properly shutdown. This prevents issues from occurring to the file system.

While the power adapter does not need to be connected to reset the SMC, it may be necessary in situations where the battery needs charging or if the computer has been without power for an extended period of time. You can also visually check the SMC reset by observing the LED on the adapter. It will momentarily turn off as the SMC resets.
