Does the power cord offer surge protection?

I have a MacBook Pro and was wondering if the 60W MagSafe Power Adapter protects against power surges without being plugged into an additional surge protector?

Nope.

Does the power-on password fully protect user data?

Hi,
I am a T61 user.
First question
Does the power-on password fully protect user data, or could someone just boot from the optical drive or another source?
Second question
If I were to use full disc encryption, could I easily unecrypt it in the future?
Thanks in advance!

As mostly with everything in life, there are pros and cons related to all sort of data protection schemes. At least in therory, everything that can be encripted may also be decripted in some way, be it via reverse engineering or some other technique. - But of course some sort of protection is always better than no protection at all, especially if you deal with lets say sensible data.
The power-on password is not a full data protection at all, to get an idea of the different password protection schemes take a look at the following short descriptions here...
--> http://www.tech-faq.com/ibm-thinkpad-bios-password.shtml
...there are some ways to reset a power-on password and informations how to do so can be found on the net. Further it doesn't help much if somebody takes out the whole harddrive of your Thinkpad.
Performing a full HDD encription, via an embedded ATM hardware chip inside the Thinkpad, or even using some OS related encription mechanism would be more secure for sensible data, as long as you don't get hardware or software trouble with those parts, which are responsible for the build-in encription/decription scheme. So it's always also a good idea to also perform additional periodically backups of your sensible data, so if some worst case scenario might appear, that you are still be able to restore your valuable data.
Hope this gives you at least a little idea about the pros and cons of both of these security schemes.

Does the power cord have a surge protector built in?

Does the "brick" at the end of the power cord have a surge protector built in? I'm wondering whether it's ok to keep my Macbook plugged in and charging during a thunderstorm or not.

So I shouldn't leave my Macbook to charge during a thunderstorm if I don't have a surge strip/adapter?
That is correct.
Get a surge protector for everyday use.
Unplug the charger during thunderstorms. Surge protectors do not protect against the damage that a lightning strike causes - they just protect against electrical surges.

Does a Laptop Warranty Cover the Power Cord?

Hi, I bought a HP Envy Touchsmart 15 and it is still covered by warranty. However, I cannot find any support help online such as the support chat which I find very odd since I just used it about a month ago when my battery died! Where did all the support go?
Anyways, when I plug in my laptop, the LED by the power port does not come on, and my laptop will not charge or turn on at all. My battery is dead, but I know it works becasue it is less than a month old. Since my laptop will not run on AC power even with the battery removed, I feel the power cord is the problem.
I would really like to know if my warranty covers the power cord, and if so how do I contact HP, since there is absolutley no information when I go to "Contact Us" besides the consumer forums.
I am a ECE student at UT in Austin, and every day I go without a laptop is hurting my grades. So I need help ASAP

Hi
Yes, power cord, adapter are covered under limited warranty. HP would replace it for you if it's faulty.

My macbook pro has been shutting off on its own. The power cord "shuts off" (does not work) simultaneously. Does anyone know what is wrong? or what could be the problem?

Does the battery recall affect the power cord jack?

My computer battery is part of the recall. However in addition to the battery problem, the jack where the power cord plugs in is not working. I brought it to an authorized repair location and was told the "bronze wore off" and that the entire interior piece would have to be replaced. At a cost of approximately $500. since it is 2 years old. My question is this: could the faulty battery have affected the jack and therefore shouldnt this problem be covered under the recall?

Absolutely. And if they give you a hassle about it at the apple store explain to them quietly that a policy which does not factor into account the damage caused by defective parts is a marketing strategy that is admonishing the proper use of a computer. Furthermore it relegates the status of a consumer to the level of non-interest in furthering the aim of the company.
Hows that? It's the best I could come up with but in light of the trouble with the SEC that this and other companies are facing this should be ample enough ammunition to accomplish the mission [but don't hassle with applecare take it to the store unless you have a warranty and in that case it would be covered].

The power cord doesn't seem to work properly. It doesn't charge my Iphone 6. Does anyone have this problem?

It looks like there's a problem with the power cord or with the connector. When I plug in the phone it starts to buzz repeatedly that sound that notices the charge is starting, but it doesn't go on. On the screen, also, the battery symbol changes constantly from black to green to black again to green and so on, so I understand it's trying to charge, but it's not working.
Does (or did) anyone have this problem?
Thank you

So today I went to an official Apple store and did some tests. As you said, the problem was the cord itself. My Iphone it's only two weeks old, so I guess the warranty will carry with a new one. As I need the phone, I decided to buy another cord. In the end, I guess I'll have two cords, which is not such a bad deal.
Thank you all for you kind answers and help.

The power cord to my hp photosmart plus printer b209a does not work. what can i do?

The warranty for my computer's printer is up, but the printer has not turned on for quite a while. After going through the HP troubleshooting - nothing seems to work. When the power cord is plugged in, the green indicator light does not light up and the printer will not turn on at all.

Here's the steps to follow if your printer isn't turning on.
If you've gone through all those steps and you still don't have power, there are a lot of places that sell a replacement cord and supply for that printer.

Does anyone know the power cord part for HP A532 printer? I need a replacement cord. THANKS!

What to do when the power cord does not connect to MacBook Pro?

This morning I went to turn on my MacBook Pro and the power cord is not "lighting up".

Try a different electric outlet.

New (3mo) macbook air screen goes black and sometimes won't come back on after I unplug it from the power cord. Any ideas why it is doing this? Sometimes I have to hold power button for 10 seconds for it to shut off then back on.

New (3mo) macbook air screen goes black and sometimes won't come back on after I unplug it from the power cord. Any ideas why it is doing this? Sometimes I have to hold power button for 10 seconds for it to shut off then back on. Sometimes holding the power button for a second is enough for it to come back on.

I took it to the Genius Bar, and they identified it as a hardware issue. Just got it back today. Parts replaced were:
620-5629 Display Module — Symptom: Distored/blurred/focus video issue
605-3284 Top Case with Keyboard — Symptom: specific key(s) do not work
So far so good. I'd suggest taking it in and not trying to work around it — it's a rare hardware issue (given the number of threads about it) and should be replaced.

My MacBook Pro 13'' shuts down randomly while connected to the power cord.

Alright, so my Mac is shutting down while being connected to the power cord. Though, when I unplugged it, it runs just fine.
I've read up on the other random shut downs but they seem to be different in my case. I was only surfing youtuve on Firefox, granted I had a few other tabs open but they weren't doing anything that would run the computer hot, and it shut down out of no where. The battery was full and it was still connected to my power cable. The screen went blank and the computer was completely off. I noticed that the light on the plug in wasn't on and switch the outlet that the computer was plugged into and replugged it into my computer. The light came on and after about three or so times of pressing the power on button it came back to life. Though, it stayed on the start up, white apple page and just spun. After a while it looked as if it was about to go to my password page but it shut down after gently moving the computer. The power cable light went off once again. I unplugged it and replugged it into my computer but the light would not come back on. After just removing the cord and pushing the button a few times my computer came back to life and I logged in as normal except for the fact that after it came back on the date and time was reset and several applications needed permissions. It also randomly logged me out of my Facetime account as well.
All in all I was wondering if anyone else had a similar problem and know what's going on or if this is new. Could it be some kind of spark in the power cable from a broken wire that made my computer shut down or is it something attacking my computer?

Please make a Genius Appointment and take it in for service.

Running an old MacBook Pro 2.5ghz core 2 Duo. Battery went chemical meltdown and expanded out of its housing. Removed it and was running off the power cord. This worked for a while. Now it won't start up. Have a Replacement on order. Is there a bigge

Running an old MacBook Pro 2.5ghz core 2 Duo. Battery went chemical meltdown and expanded out of its housing. Removed it and was running off the power cord. This worked for a while. Now it won't start up. Have a Replacement on order. Is there a bigger issue or does a battery need to be in the compartment to boot up? Appreciate any help. Thanks.

Working battery needs to be in for the computer to function.

HT4061 I updated my phone this morning and now it is stuck with an iTunes logo and arrow pointing to it and a pic of the power cord - the phone was plugged in when I started the update...now I can't access my phone at all

My phone is plugged in and the screen shows the power cord connector and arrow and the iTunes logo. I have made sure the plug is in and power on. Touching the screen does nothing. I have turned it off and back on I get an apple pic then back to the iTunes logo pic, arrow and plug....

I installed new update and have had the connect to iTunes all day. I got home connected to iTunes and it said my phone couldn't be updated it needed restored to factory settings. I was reluctant to lose everything so I ignored this and clicked update. After it installed it said to restore again. Again I ignored it and this time it updated my phone and my phone turned back on with everything there.
So glad I ignored the previous messages asking me to restore! You could try this if you have iTunes and don't want it restored to factory settings.

I attempted to update to the latest IOS version. Then it seemed to "Lock UP". Now all i get on display is a graphic of the power cord with an arrow pointing to an iTunes icon. Home button is not responding.

I attempted to update to latest version of IOS. Now all I get on the display is a graphic of the power cord with an arrow pointing to an iTunes icon. Ipad does not seem to power down or power up correctly. Home button is not responding.

I am new to this, could you provide me with a little more detail on how to do this? Thanks so much!
