Using a non-grounded outlet

will using a non-grounded outlet damage my macbook? i just found out the outlets in my apartment are not grounded...i've only been living here a few weeks, and i haven't noticed any problems, but i don't want to risk frying my beloved laptop.
any advice?
thanks!
--p.trina

Shouldn't be a problem since the two prong adapter that is on the magsafe adapter is not grounded.

Non grounded HP Laptop have electrical feeling on usb ports

I am living here in the Philippines now and have brought my Hp laptop dv9000. Whenever I turn on the laptop with the AC I get this electrical feeling in the usb ports. When I run with the battery I feel no electricity. Since the AC can take a 100-240V input, the outlets here in the Philippines are 240V, it shouldnt have any problems. But the charger has a 3rd prong that is used as a ground, but the wall outlet only has 2.
To better understand by setup: 1. the electrical outlet has 2 prongs that lets out 240V, 2. I have and AVR (automatic voltage regulator) so I can lower the voltage for my, 3. UPS (uninterrupted power supply) that only takes in 110V. I plug in my AC charger to the UPS to power my computer.
So my question is what can I do now to stop the the electricity coming out of the usb ports? Do I need to install a grounded socket?

Have you tried restarting the laptop? Many times we get simply put the machine to sleep or hibernate- a full shutdown/restart can help with usb problems.
You might also try disabling "USB Selective suspend" in your Power Options plan.

No grounded outlets and the Mac Pro

I live in an older house w/o grounded outlets and have been using the small plug adapters that go on the end of the power cord.
What are the ill effects (if any) of using my new Mac Pro in this configuration?
Thanks

Not a lot of risk. Electrocution and fire.
I assume it (house) is not so old as to not have plumbing?
Get a 2 to 3 prong adapter with a ground tab. Connect a wire from the ground tab to a water pipe with a clamp for this purpose (from Home Depot) . Plug the MacPro into the now grounded outlet.
http://www.trianglecables.com/polarized-grounding-adapter-3-prong-outlet-to-2-pr ong-plug.html (75 cents plus the wire and clamp)
These ones use the screw for the cover plate to ground the adapter to the house, though you need to make sure there is a metal box and that box is grounded. Or use the pipe.

Power adaptors - some require connections to grounded outlets others not. Why difference in advice ?

For my elitebook 2570 P laptop:
Some 65 Watt HP adaptors require grounded outlets (e.g. series PPP009H part no. 519329-002) and 80 watt travel adaptor HSTNN-DA22, part no. 601-485 001, but others do not require grounded outlet: series PPP009L, part no. 384019-001.
Why does HP give different advice on the correct uses of these adaptors ? What should be the advice ?
rgds,

Now just a filter & hub plugged to the bottom of the master socket as request.

First off, i think it's sad that i have to use my non apple device to post this question... Why has my iPad become absolutely useless after updating to iOS 8.1? I am unable to use my mini because it crashes, slow performance, major battery drain.

Restore iPad to Factory Default; do not restore from backup. It may be the cause of the problem.

Trying to use the same ground for more than two channels (RSE configuration) with usb 6000

Hello,
I'm currently trying to set up a LabView code in order to get readings of voltage using 5 different locations simultaneously. I want to only use the first location as ground and obtain 4 voltage measurements between the ground and each one of the other 4 channels. I'm using a usb 6000 which for now allows me to use the same ground for only two channels. Is there a way to use the same ground for 4 channels?
Thank you,
Maria

You're right it is confusing the way I describe it so I ahve attached some pictures of the set up. The first figure is the cell filled with soil and the 5 probes inserted in it. The anode is placed at the left end of the cell and the cathode at the right end but they do not appear in the figure. I'm trying to use location 1 as gournd and take measurements of voltage from the following pairs: 1-2, 1-3, 1-4, and 1-5. The second figure is the DAQ I'm using. When I was trying to set up the RSE configuration, it was ussing ground A for the channels 6 & 7 (locations 2 and 3 in figure 1) but ground B for channels 4 & 5 (locations 4 and 5 in figure 1). What I am asking is which is the best way to use the signal from location 1 as the ground for all 4 channels. Is this more clear?
Thank you for your time!

Can I use a non apple wireless hard drive with time machine?

Can I use a non apple wireless hard drive with time Machine?

Some NAS (network storage) systems do claim to support Time Machine, with varying levels of success. For example, the Synology units have this feature. They're not officially supported by Apple, though.

Can Jdeveloper Be Used For Non-Oracle Databases

I have been trying to evaluate Jdeveloper 9i and Jbuilder 7 Enterprise for Swing database development. I am particularly interested in the productivity enhancements such as BC4J and Jclient. The underlying database might be Oracle, SapDb (excellent, easy to use, and free), SQLServer, etc.
I evaluated Jbuilder Enterprise tools and it worked flawlessly with SapDb. This emphasized using their DataExpress and DbSwing components which provide many useful capabilities similar to BC4j and Jclient. It also involved using their DBPilot tool which allows browsing similar to that provided via a Jdeveloper connection.
I tried to use Jdeveloper for the same SapDB and it is essentially non-functional. I followed the instructions for using a non-default driver and tried to define a connection. It behaved inconsistently: often saying no suitable driver can be found and yet when you edit the connection and test without making any changes, it works. If you try to establish a BC4J definition, it is very inconsistent and fails to recognize important details as foreign keys. Even if you define a ViewLink manually, it still does not work properly if you attempt to define a Master-Detail Jclient form. As I have stated, all these types of capabilities worked flawlessly in their Jbuilder equivalent. Furthermore, I really like the fact that Jbuilder gives many of BC4Js benefits without needing a BC4J J2EE container.
Has anyone had real success using Jdeveloper's advanced features to develop for non-Oracle databases and if so, how did you get around these types of problems?

Hi,
generally, SCAN can be used for 10g databases and you discovered the first half: for 10g databases you will have to modify the REMOTE_LISTENER entry for each 10g database instance to point to the SCAN listeners (as opposed to pointing to the remote local listeners, which is the default in 10g). You could even have the databases registers themselves with SCAN and the remote listeners, if you wanted to... It's more or less a matter of configuration. But for simplification reasons, I will stick to the case where you have your 10g databases register with the SCAN listeners only.
Now the other half is the client and the client configuration. An 11g Rel. 2 client configured for RAC would have a TNSNAMES entry that has only one address line for the RAC databases. The host entry in this one address line should point to the SCAN (the SCAN name is ideally resolved in DNS). A 10g client configured for RAC would have as many address lines in the TNSNAMES as you have nodes in the cluster.
The 10g client SCAN configuration would then be in the middle so to speak: You would have 3 address lines in your TNSNAMES, in which each host entry would resolve to one SCAN address (I assume you will use the recommended default of 3 SCAN IPs). If you choose, you can have a name resolution for each of your SCAN IPs, but this would not be required. Now, why would you do it this way? Because this configuration will always work and does not make you dependent on certain functionality that your DNS server may or may not offer.
For the remaining questions: SCAN is a DNS entry resolving one name to more than one (typically 3) IP addresses. OID is short for Oracle Internet Directory, which is a complete LDAP server. And you are right that there is no document how to configure 10g clients for SCAN from Oracle yet. However, there is a quite good document on SCAN on otn.oracle.com/rac, but I am sure you are aware of it already.
Hope that helps. Thanks,
Markus

Can i use a non-apple keyboard with my imac?

can i use a non-apple keyboard with my imac?

Welcome to the Apple Support Communities
You can use the keyboard you want with your iMac. However, note that some keys, as the Command key, aren't present in non-Apple keyboards. For example, in a non-Apple keyboard, you have to press the Windows key because that's the replacement of the Command key of an Apple keyboard

Use the Non-Touch Version of Aurora

In Windows 8 (and 8.1), the touch version of Aurora completely dominates the Start Menu, making it very difficult to use the non-touch version.
I also try pinning a shortcut to the non-touch version, but in Windows 8, every time there is an update, it overwrites my shortcut with the new touch-enabled icon. In Windows 8.1, I simply cannot pin a shortcut to the non-touch version. Additionally, pasting a shortcut into the Start Menu folder doesn't work either. Previously, in Windows 8, I could paste the shortcut, and it would appear "as is," but that no longer works in Windows 8.1. This is getting extremely annoying.
I have tried to submit feedback about the before, but in the past few weeks, the issue has remained unresolved.

I can see that they are entirely different, but I am looking for a workaround, since, as I said, I don't use desktop icons (nor do I want to). Other applications have two different Start Menu icons, so if there is a workaround where I can create a new icon that opens the desktop version, then I would appreciate that.

Using NI & non-TDM plugz on HD/2 system with Logic 8 as front-end

For the life of me I can not figure out why in Logic 8, using a TDM Configuration, why I can only use what looks to be TDM plugz in my session?
I used to love being able to run Guitar Rig as a DAE channel in Logic...
Did Apple do away with RTAS support in Logic 8? This config worked fine using my G4 with a mix plus system in Logic 7.1.1
So now the only way I would be able to use my non-TDM plugz in a Logic 8 TDM configured session would be to use the Core Audion functionality alonside the DAE/Direct TDM functions as well? One would think this could create many problems for my lit'l MacPro to not flake-out on me having two audio configurations running at the same time.
Any input or similar issues with this matter would be greatly appreciate.
Thanks,
Ryan

There was never "RTAS" support in Logic, you are referring to "HTDM" support way back then.
But it was Digidesign who abandoned "HTDM" support.

Thinking about GuitarRig and the needed audio input you should run CoreAudio in addition to DAE and deactivate DTDM (DirectTDM) because of missing audio inputs.
Any input or similar issues with this matter would be greatly appreciate.

Planning using the Non-Cumulative Key figures

HI,
In my reporting requirement for IP, I need to get some actual values from the cube 0IC_C03. The key figues which I required are 0VALSTCKVAL and 0TOTALSTCK, but these 2 are non-culative key figures. When I selected these 2 key figures in my aggregation level, it is throwing an error message as "InfoObject 0VALSTCKVAL(Version A) is not compounded and Aggregation level is inconsitent".
I read in some document that, it is not possible to use non-cumulative keyfigures in ALVL.
I searched in SDN and SERVICE also, but some documents are saying that, in new path level (19) it is possible. Now I using the path level 18 only. In this case how we have to use these non-cumulative keyfigues,, please sugguest me...
Thanks in advance...
Regards
Rajesh

Hi
Non-cummulative keyfigures are not supported fro planning and teh error thrown is correct.Please find the help link which gives what are supported and not supported as part of aggregation levels.

Can I use a non-sinewave inverter to power my macbook

Some power supplies can not tolerate the output of inverters that are not sine wave. I don't want to experiment using my non- sinewave inverter and find out that the Magsaf power adapter smokes.

You should use your serial number to lookup the Technical Specifications for your MAC. The current MB specs are:
Electrical and operating requirements
Line voltage: 100V to 240V AC
Frequency: 50Hz to 60Hz
Operating temperature: 50° to 95° F (10° to 35° C)
Storage temperature: -13° to 113° F (-24° to 45° C)
Relative humidity: 0% to 90% noncondensing
Maximum operating altitude: 10,000 feet
Maximum storage altitude: 15,000 feet
Maximum shipping altitude: 35,000 feet
You can go ahead and test it on the inverter. The voltages produced by the inverter - whether a proper sine-wave or a chopped square-wave - are safe for your adapter.
What you need to test is that the adapter does not "need" an accurate clock signal. It is common for desktop computers in North America to use the 60-hz sine-wave for a timebase in the DC output regulator.
Square waves don't have the same zero-cross timing as a sine-wave, so the output voltage would not work with anything but a true sine-wave inverter.
I doubt your adapter will care since I have yet to see any laptop or portable with an external p/s that does.
Pop out your battery, and see if you can boot from the adapter on the inverter. If you can, then your good to go!
Let me know how it works out.

How to use a non-standard true type font that won't be changed by the native environment on others' computers when they open the document?

We are using a non-standard true type font (Zurich Ex BT) when creating a .pdf document but when others view it, the font is changed on their computers. How do we use this font and keep it from being changed when others look at it?

This is actually good stuff and well written but I hesitate to advise people to use either the "oven trick" or really even the heat gun method as both are notriously short-lived even if they appear effective. Your far better bet is to send the board in to one of the vendors on the internet who are set up to do a proper reball. Even those fixes are good for maybe 12-18 mos. But again, you get a high grade for spelling it out.
