DV4 Battery Issue - Battery Charges; But Laptop Won't Run From Battery Power

Greetings,
I have a DV4, and let me tell you - I am so over this laptop. I have had it for over a year, and in that time, the backlight went out 6 months into owning it, the battery died just after the one year mark, and the webcam has been broken since I sent this computer back to HP to have the backlight issue resolved. I will never buy a new HP ever again.
Now, the battery I have replaced in my laptop charges - but, when I unplug the laptop from the wall, the battery power does NOT switch over. I have had this battery a total of two weeks - it was working fine until last night. Any ideas?
Thanks!

Hi, SoCal Cal. Take a good hard look at your battery contacts: both the ones on the battery itself and the "prongs" in the PB case that engage with the slotlike contacts on the battery. Are any of them significantly darkened/tarnished? Is there any debris or fluff on or in them? Clean out any foreign matter, then insert and remove the battery at least a dozen times in succession to see whether doing so will wear away any tarnish that may be impairing the necessary electrical connections. There's not really any easy, better way to clean the contacts, at least not the ones in the slots on the batttery itself. Then test again.
It sounds to me as though not all of the battery contacts are making good contact — though some of them obviously are, at least some of the time. Perhaps "working" the contacts this way will improve matters.
I really don't know what's going on with your machine; these are just shots in the dark.

HP Pavilion battery healthy and charged but laptop is not running on battery

A serious and odd problem has developed with my Pavilion (HP 15-N096EA PC)
I removed the battery when the machine was switched off and pressed the start button as this procedure was suggested on a site for clearing malware issues.
Since then, my laptop has refused to run on battery. Behaves as if there was no battery in it. The Pavilion is relatively new, the battery is in perfect condition, charges to 100% and keeps the machine running for up to 6-8 (!) hours. Not kidding.
Even now, the mains connection charges the battery, the little icon says so in the system tray. It is now 100% charged.
But when I unplug the mains adaptor the whole thing dies immediately.
I applied electric contact cleaning liquid to the connection ends of the battery, even measured the voltage in the battery with the tipped ends of a volt meter. All reading perfect values, yet the computer has stopped working from battery.
An hour ago this computer worked completely well on battery, but since the current "draining" exercise absolutely nothing. Tried all sorts of options: Taking battery in and out while on mains, nothing doing. If I am correct, battery calibration can only happen with the computer running on battery and this computer refuses to run on any battery.
What has happened here please? ANY HINT,ADVICE, SUGGESTION from professionals, non-professionals most desired and appreciated. Thanks.

MACBOOK I had the battery tested it is fully charged but laptop will not run unless plugged in

My macbook (early 2009) battery is not working. After I disconnect my charger from my macbook, my macbook completly shuts off. So I ordered a new battery and the same thing is happening. Accordingly, I went to batteries-plus to make sure I didn't get a defective battery. The store said there was nothing wrong with the battery so it has to be my macbook. I've reset the pram and smc and that as had no effect as well.
Can you tell me what the problem is? Or other ways to troubleshoot?

One of the items which could have failed, is the 'magsafe board' where the
circuit is inside the MacBook, adapter attaches outside. This is similar to
a dc-in board, however can be tedium and difficult to repair if unskilled.
Not sure about troubleshooting this issue; a few topics on the subject have
been posted online and also in these ASC discussions; & are searchable.
At times, a google search may bring up more; while if you can find them,
the Support articles can be helpful if they go into a actual troubleshooting.
Some do not offer a level of technical help required, and a service tech
often would have the correct diagnostic tools to be able to test this issue.
The magsafe board replacement involves a take-apart process and there
are several parts that can be difficult to put back where they came from;
so if you go there, read up on how others did it. An easier said than done
if one has no experience with completing multiple step tiny tasks.
You could look into the repair guides at iFixit.com MacBook section
for some ideas; several DIY processes are shown in pictures.
Not sure about batteries plus. For their factor, you could get a fairly
nice third-party one from OWC with higher specs. Do they allow a
return if the product did not solve the issue? (seldom is expected)
Good luck & happy computing!

Laptop won't run on AC power

Hi,
I have a Compaq Presario CQ50 and just ordered a replacement battery. When I get it, I plan on only using it when I need to. The problem is, my laptop is not seeming to be able to run on solely AC power. Every other laptop I know is capable of running without the battery in it, so I'm thinking that either my budget-priced laptop was designed poorly and is incapable of this feature, or that something is wrong with my laptop and I need to send it in.
To be precise, it does actually run for a few seconds on AC power, when I boot it up. But when Windows tries to start, it shuts off. Just a detail worth mentioning.
Thanks,
Roman

This is usually a symptom of a bad power jack.
The part looks like this:

Sorry to say your jack is soldered to the motherboard and it is a pretty big job for the end user to try to fix it.

There are numerous repair services on the internet and you might have a shop right in your town that can do it.

Crontab won't run from root

Hi,
I'm on 10.3.9 with a crontab issue.
It seems crontab won't run from root. The crontab is set to run a test script every hour, 00 * * * * /Users/station3/bashscripts/cronscript1
but it won't. I can run the script from the terminal while logged in as root just fine so i dont think it's a path to the script or permission. I get no errors either, it just doesnt run.
I can run the script from the crontab of an admin user just fine.
Any ideas?

I can see that yes, when i run cron it's in a
different environment, but which one?
It uses the root environment. When you use sudo -s, you're getting root privileges, but keeping your regular login environment. If you want to truly become "root" with all the , you'll need to use sudo su -. That'll give you root's environment.
The simplest way to add an environment variable to a crontab is to just stick it at the top of the crontab. I always add my email address to my crontabs:
MAILTO='[email protected]'That makes it easier to control where I get the email sent if there's output of some kind. You can also add the usual ".bashrc" and ".bash_profile" files to root's home directory at /var/root, but I'm not certain how to make cron see those without rebooting the computer. Read the bash man pages, particularly the invocation section for more information.
When I run it from the crontab, several, but not all
subfolders have had thier USER permissions changed to
"system" and I cannot access them.
How do I get around that?
Try using the -p switch with cp. That's alleged by the cp man page to preserve user ID, permissions, mod time, etc.

Took apart Macbook pro 13 to remove broken headphone tip in the jack. Had to remove battery to get to the headphone jack. Now the laptop won't start. The power button is just not responding. Battery indicator showed charge of 3 dots initially but now only the last dot is blinking. The power cable used to light up green initially but now the green light is gone. I have tried SMC reset, which didn't work. What are my options?

Make an appointment at the Genius Bar. There is no magic that will fix broken hardware.

My iphone is fully charged but it won't let me slide to unlock

My iphone is fully charged but it won't let me slide to unlock or won't let me slide at all, what do I do?

Have you tried resetting the phone? Press and hold both the sleep button and home button until the screen goes blank and then the Apple logo reappears. It can take a little while so be patient.

I can't get my iPod to turn on. I tried charging but still won't turn on.

I can't get my iPod Classic to turn on. I tried charging but still won't turn on. This happened once before and someone told me a way to turn on by holding a series of buttons down at same time. Does anyone know how?

dkstahlman,
With the iPod still plugged into an external power source, press and hold both the Select (Center) and Menu buttons together long enough for the Apple logo to appear. This may take 1 or 2 tries.

Hi, I have adobe acrobat 6.0 but it won't run on windows 7, is there an update availabe?

Hi, I have adobe acrobat 6.0 but it won't run on windows 7, is there an update availabe?

I agree with Doc, but there may be a work around. Actually, your best solution is to just buy AA XI. The work around depends on what you mean by does not work. Do Acrobat and Distiller both install and appear to function? Is the problem one of not being able to print? If both of these answers are yes, then you can install an independent PS printer (maybe one from Adobe or one of the HP color PS printers), change the name to Adobe PDF for your use (not required), and change the port to FILE. Then to create a PDF you would print to that printer and open the file created in Distiller to create a PDF file. May or may not work. However, AA6 is so old, it is likely to cause other problems, even if this process works. If nothing else, it will not open some of the newer PDFs that are being created today (at least I would guess that will be the case). So buying XI is really in order.
Other issues that may crop up will be activation (will likely fail) and updates that have to be obtained from the FTP site and not the web.

I have installed the latest OS X Updaate 10.8.4 - several times on my iMac, with restarts, but it won't disappear from my App Store update list. Why?

I have installed the latest OS X Updaate 10.8.4 - several times on my iMac, with restarts, but it won't disappear from my App Store update list. Why? ..and how do I get rid of it?

I had a similar problem with trying to update using the App Store, and being told that the software was "installed" yet I was still only running 10.8.3.
The App Store was continually saying the 10.8.4 was available but with many tries I still could not download or install it.
And there are a few links to the OSX 10.8.4 (Combo) update that actually lead to a "Cant find this page error" on the Apple site and the App Store.
I did find a link to just the vanilla flavoured OSX 10.8.4 update here http://support.apple.com/kb/DL1658 which is a smaller download of 359mb rather than 849mb with the combo update.
The simple OSX 10.8.4 update downloaded fine with Safari and I installed it with no problems from the finder. A few opening's on closing's of the App Store app made the update flag finally disappear.
I have since come back here to report this and then found the link to 10.8.4 Mountain Lion Update v10.8.4 (Combo) at http://support.apple.com/kb/DL1659 above and found that this link also starts to download the update through Safari and while I decided that I no longer needed it, I would presume that it would still install fine from the finder like the OSX 10.8.4 update did.
So it seems to me that there is a problem with (maybe occasionally) updating from the App Store, but if you download from either of the two "hard" links above and install from the finder it should be fine.
