What do I do if my Macbook Pro isn't charging?

Hey , so I purchased my MacBook Pro early 2011 . I use it pretty much everyday and for maybe 4-6 hours in a day. I currently read that charging it all day while it was on sleep wasn't a bad thing. So I was charging it and using at the same time and when I was done using it I would just put it on sleep and leave it on the charger all day. But sometimes I wouldn't charge it while using it and left would put it on sleep without charging it because I would get lazy to get up and charge it. So, I charged it yesterday and used it . And today I was going to plug it in to charge and it wouldn't charge . I needed answers so I searched on google and there was so many suggestions like maybe considering buying a new charger or even changing the battery . The charger seems in good shape and I tried plugging it in to different wall sockets but nothing changed. I even left it for about 2 hours and then came back to try charging it again. I do not want to buy the wrong thing and spend a lot of money. Currently I have around 30% charged and I shut it off so it wouldn't die completely. Can someone help me out, please? I need some answers ASAP. Btw, sorry for the long paragraph. I don't want to miss a detail . Thanks Guys (also I am not completely sure about the type of operating system , down below)

What is the normal temperature for MacBook Pro's when charging?

I really wanted to know because sometimes I feel like my MacBook Pro is too hot. I don't want anything to melt in there. So I decided to download a temperature monitor.
What is the highest healthy temperature a MacBook Pro can reach?
Also ---
What is the average temperature of a MacBook Pro?
Thank you so much! Any help would be greatly appreciated.

Hi
I have a NewerTech external charger with an inbuilt battery calibrator. It provides 2 charging methods: it either fast charges or conditions (calibrates) the battery. Fast charging, which fully charges the battery in about 2 hours, causes the battery to noticeable heat up. However, conditioning, which discharges then recharges the battery, is so gradual that the battery remains cool (at ambient temperature).
The charger has 2 slots (for 2 batteries) and will charge or condition 1 or 2 batteries but not at the same time. For example, it will fast charge one battery and when finished switch to conditioning the second battery. This charging regime means the universal power supply connected to the charger can be less powerful (and smaller), i.e., it will deliver sufficient current to fast charge one battery at a time. Batteries may be left in the charger which automatically switches to trickle charge when continuous charging finishes.
The heat generated by the battery in the MBP is caused by fast charging and whilst I have never made any temperature recordings of the base of my MBP I can confirm that sometimes it gets so hot that it can be painful if in contact with the skin, e.g. resting on ones lap. This is normal. The battery also heats up when the MBP is running solely on battery power. Excessive heat could indicate a battery fault and it should be removed and examined immediately as any distortion, e.g., swelling, can damage the MBP.
An external charger/conditioner is useful if you have a spare battery, or two.
Regards
Phil

My MacBook Pro isn't charging

I've tried the options in the trouble shooting guide, checked the connectors, shutdown and restarted and still nothing. Can anyone help? Of course my warranty has just expired!!!

You may be having an issue with your power adapter (I'm assuming that there's no 'green' light on it? Is there an 'amber' light?) or a problem with your internal power management.
To see if it's strictly a system management problem, try both of these things:
Resetting the SMC
Resetting PRAM/NVRAM
...if no joy with either, then you'll need to take your machine into your local Apple Store/AASP for diagnosis.

How do I know what files to remove from my Macbook Pro laptop?

Apparently my hard drive is full and I need to remove files so I have space to download more music and movies. I don't want to delete important files. How do I go about doing this?

How do I know what files to remove from my Macbook Pro laptop?
Remove only files you yourself stored on the laptop; files in your Home folder. Don't delete any files from the system libraries, and if you want to remove applications, use the provided uninstallers.
For files in the media libraries - iTunes, iPhoto, iMovie use the application to delete music, photos, movies.
If you are planning on storing more movies and music on your mac, deleting old files will probably not suffice alone to free enough space. Consider to get yourself an external drive to store your media.

1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. XProtect, Gatekeeper, and MRT reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use the software unless a network administrator requires you to do it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

What wireless routers work with the MacBook Pro?

I have been having problems with my inconsistent D-Link 624 and I realize that I will have to replace it.
I would like to know what routers are compatible with the MacBook Pro. My D-Link worked fine with my iBook but I think it does not work with the Intel binary. Any suggestions?

I had problems with a number of different Linksys routers (dropped signal, couldn't connect to some iChat AV calls, etc). I'd been using some Airport express routers for music around the house, which I switched around a made a primary wireless router and a reange exapnder. I've had ZERO problems since.
BTW, I was having almost identical problems with my PowerMac G5 (with a wireless card).
I'm curious if something in recent upgrades (10.4.7?) has changed the OS's ability to connect reliably with non-Apple routers.
But at least my Apple routers seem to be working very well.

what can I do? my macbook pro rejcets to eject any cds or dvds I put on !!!

The drive accepts discs but they do not mount or are automatically ejected
Check the disc's surface for scratches and dirt, since these things can prevent the disc from appearing on the desktop.
Reset the Power Manager (PMU) or System Management Controller (SMC).
Ensure your drive can read the specific type of disc being used. For example a "combo drive" can read a DVD-R and burn a CD-R however it cannot burn a DVD-R. The utility System Profiler may provide additional information regarding what media your computer supports.
If the discs continue to not be recognized, please contact Apple, contact an Apple Authorized Service Provider, or make an appointment with an Apple Retail Store for additional troubleshooting, evaluation, or service.
