MacBook charger not working no light
You can not assume that the charger is at fault.
You need to,check the charger.
If you are not handy, and have like a voltmeter,,you may not be able to do that.
May be you could get to a store which sells,Macbooks and see if they have a charger that will fit your machine to see,if their charger will charge your machine.
Then you can say for sure your,charger is at fault.
Fixing could be a problem,especially if you are not knowledgeable in electronics.
Just get a new charger.
MacBook Pro charger not working
MacBooks have a long history of faulty charger connectors, my first doubt is your megsafe connector is broke.
Try any friends charger and see if it works.
If not take it to the service center because the second most common problem with MacBooks is shorted power boards.
MacBook charger not lighting up but charging
The original Magsafe adapters have a chip that communicates with the MacBooku2019s System Management Controller.
When the SMC u2018seesu2019 that the adapter is correctly connected, it gives the adapter the green light to start giving a charging current.
,The knock-offs donu2019t have that chip; these just give out a current immediately.
Thatu2019s also how you can tell if your adapter is an original; it takes a second for the charge indicator to light up.
nThis also means that, should you accidentally connect the knockoff magsafe like this:,u2026 you run the risk of frying the SMC on your logic board.
,Thatu2019s why you should buy the original adapter, not the cheap knockoffs; Logic board repairs are way too expensive to justify using AliExpress-shit.
macbook not charging usb-c
Can the MacBook Pro be charged with any USB-C charger?Thereu2019s some confusion in existing answers about how powerful the charger needs to be for a MacBook Pro.
It is NOT true that the charger needs to have the same power as the original provided by Apple, not by a long way.
,A large part of the reason for this is that nearly half the power rating of Appleu2019s charger is provided to power the MacBook Pro itself whilst the battery is charging.
In fact this excess is there to make sure that the battery charges just as quickly even when the MacBook Pro is working flat out.
However of course most of the time the charger is in use the MacBook Pro is relatively idle, or even sleeping.
,When the charger is connected then the MacBook Pro will take what it needs to run from the charger and then feed up to the rest thatu2019s available into charging the battery as required.
So as long as the charger can provide more power than the MacBook Pro is using itself then it will charge the battery.
,To put some figures on this, my MacBook Pro 13u2033 is supplied with a 61W USB-C charger.
When empty the battery uses at most around 35W of this, in that Iu2019ve never seen the charging power exceed 35W when the MacBook is sleeping for example.
Additionally when the MacBook is idling along whilst I do typical work, such as web browsing, messaging, viewing photos, watching YouTube, reviewing emails, etc.
then the MacBook usually uses less than 5W.
So any charger significantly exceeding 5W will charge the battery.
Iu2019ve even successfully used a 10W charger.
,In fact I regularly use an 18W USB-C power bank to charge by MacBook on the go.
If I use this whilst the MacBook is sleeping then it charges the battery at better than half normal speed.
But more than this, the maximum charging power used by the battery drops off progressively after around 65% full anyway, and for the final 15-20% of the charge the 18W charger is charging as fast as the 61W charger would.
The net result is that with the 18W charger a full charge requires around 2 hours 20 mins, compared to around 1 hour 40 mins using the 61W charger.
,Even if Iu2019m using the MacBook Pro normally then thereu2019s still typically 12u201315W charging power left from the power bank to go into the battery.
This obviously takes longer, but still has no problem charging at all.
,Itu2019s only when Iu2019m using the MacBook Pro to do intensive work like video processing that the 18W charger cannot keep up, and I need to resort to a more powerful charger on the rare occasions that I want to charge the battery at the same time.
But nothing bad happens if I donu2019t - the MacBook Pro just supplements the 18W provided by the power bank with power taken from the battery in order to run itself.
So running like this the battery in the MacBook Pro will last twice as long as when the power bank is not connected.
