Under battery power supply Tecra A7 works slowly

I have a notebook TECRA A7, and I have some problem with the battery. When I don't use alimentation AC, the notebook gets too slowly with programs like Netbeans.
How can I solve this problem?

Hello
To save battery power and allow longer notebook usage Toshiba has designed Toshiba power saver tool. As you can see there are few different power profile available. If you use battery power supply it will be automatically switch to Normal profile and there is CPU speed set to lower level. You can change it manually and set to maximum performance.
NetBeans software is not known to me but it is possible that notebook runs slowly if software needs more CPU power.

Dead B&W G3 ? Only the power supply seems to work...

Hi Everyone...
Here's my setup:
Powermac G3 B&W Rev.B
Processor: Powerlogix G3 750FX (1Ghz)
Ram: 1GB (4x256Mb)
OS 10.4.9 (latest OS supported by Powerlogix)
HD: IBM desktar 120MB
DVD-Rom: Samsung DVD-/+R
PCI 66Mhz -> Radeon 9200
PCI 33MHZ -> M-Audio 2496 Audiophile Audio Card
PCI 33MHZ -> Sonnet Tango 2.0 (USB/FW)
PCI 33MHZ -> Sonnet Tempo ATA133 (my main drive uses this card)
The B&W G3 has been one of my hobby machine for a year (I mostly use it as a jukebox to listen to AIFF disc images in PCM / uncompressed sound).
Anyway... it died on Saturday night... just after upgrading to a Sonnet Tempo ATA 133 card...
As I've been a Mac user for a long time (and I've been there before with a Gossamer MB in my beige G3 which died out of the blue once), I completely did empty the motherboard... adding one element at a time to isolate the issue but the fact is that:
a) no startup sound
b) black screen (nothing comes out of the Radeon 9200)
c) only the power supply seems to work
d) even when plugging the HD into the MB IDE socket, the HD doesn't even activate itself (no boot).
Of course, I went through the CUDA switch, tried to reset the PRAM, checked the jumpers on the HD (master position)...
I also tried to boot the system off the OSX Tiger Install DVD but nothing...
I have a feeling that my MB may be DOA.
What do you think ?
If this is the case, since I'm using a Tempo ATA 133 PCI Card, does it make any difference to replace it with either a REV.A or B MB ?
Thanks for your help,
Pierre André.

Hi Grant,
I posted the following on another thread, but I haven't gotten any response.
I'm having a similar problem with a B&W 350 MHz (rev 1 I think). I get the start up tone and nothing appears on the monitor. Not sure if the machine is actually booting or not.
I am trying to repair this machine for a friend. They had been having a problem with the machine booting into a blue screen. I suspected a corrupt directory, so I ran Disk Utility (from another machine) and also Disk Warrior. Both Disk Utility's Disk Repair feature and Disk Warrior found problems. Disk Warrior was able to successfully rebuild the directory.
I had removed the hard drive from the machine and put it in an external casing in order to run Disk Repair and Disk Warrior. Upon putting the hard drive back into the B&W and booting the machine, I was able to successfully boot the machine into Tiger. I tested the machine for a few minutes and it seemed to work fine.
Next, I ran software update and installed a new version of Safari and then after the required re-boot, tried to repair disk permissions. During the repair of disk permissions, the machine froze up completely. The clock stopped ticking and there was no mouse or keyboard response. I tried using the re-boot button on the front of the machine, but the machine would not fully re-boot. I get a boot tone, but no video.
I tried re-setting the CUDA chip by pressing the re-set button on the logic board, but to no avail.
Finally, I did take the battery out and had it tested at Radio Shack. The battery is showing a good 3.6 volts.
I have a second B&W (300 MHz) that is basically doing the same thing. Do you know what could be causing the lack of video signal?
Cheers,
Thomas
PS: I tried re-setting the logic board as described in another post (unplugged machine, pressed power button, removed battery, waited 10 minutes). I have tried the CUDA reset several times, but I only press the button for a second, not 15 seconds. I have re-seated the RAM. I have removed all the RAM and tested each. Nothing seems to work.

HT201263 my ipod touch 4th gen isnt work after a long time with 0 percent battery power.Then its not working. computer doesnt respond to my ipod .only black screen is appearing it even not wake up after reset it what can i do please help me

my ipod touch 4th gen isnt work after a long time with 0 percent battery power.Then its not working. computer doesnt respond to my ipod .only black screen is appearing it even not wake up after reset it what can i do please help me

After being connected to a charging source overnight try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Satellite C660 - WLAN disconnects on battery power supply

HI
I have a new Satellite C660 which is a great wee machine BUT every time I disconnect the power cable the wireless connection looses the internet connection. Wireless is fine and all settings accurate. I have checked the amended the power settings and they are set to be ok whether on battery or power.
But still I cannot disconnect the power cable without losing the warless connection. The modem is still on and functioning and even more strongly I can access other peoples wireless connections whilst being off line.
Please any ideas?
Thanks

When you use notebook on battery power supply and use FN+F8 can you enable and disable WLAN module properly?
Ave you checked WLAN settings in device manager properties (click here )?

My MagSafe Charger / Power Supply is not working

I am using mid 2009 13" MacBook Pro with 85W MagSafe . My operating system is Lion 10.7.4.
I heard a "click" coming from the direction of where my charger and just before and now its not working.
The light is not coming on the charger itself
No power is shown be coming into the computer on the Desktop toolbar either, nor does my computer that there's a charger plugged in.
I have tried the charger in a number of the different sockets around the apartment and still no joy
The transformer "block" is cold
Could this be a s simple as a blown fuse in the plug or something else altogether?
I need to fix this asap. No power = no computer. All help much appreciated.

I've copy and paste info from under AC. The MagSafe charger is physically connected, the report says that is not connected and not charging.
Any tips on where I can get cheap new Apple charger (60W MagSafe)? Thanks to you
both.

New battery/power supply problems

i bought my ibook on ebay, put in some upgrades and am pretty happy with it. One thing keeps making me extrememly angry. Randomly, without warning, the power supply cuts out. When I look at the port, the light's still on. This wouldn't be so bad because usually the battery would kick in. However, mine came without a battery. So, everytime my power supply cuts, the computer shuts off. What's the problem?

Mike,Check your Energy Saver options (Apple Menu > System Preferences > Energy Saver > Options Tab > 'Schedule' make sure this isn't set to turn off your iBook.
I'd also try resetting the Power Management Unit. (Click this link and follow the instructions).
At least your clamshell's a good deal lighter! (Doesn't it tip back too easily without the weight under the front?).
The problem with running a machine like this is that the Clamshell has no internal battery (unlike every other Mac ever!) this means that you really do need the main battery for correct operation of the system. You'll be forever re-setting date/time etc so it may be worth inv a main battery - even if it's a really cheap one that only gives you 10 minutes run time - it will guard against this type of problem.

17"display with extern power supply won´t work

Hi there,
my second display a 17"apple studio display (CRT with VGA) just works every now and then. Can´t locate what´s wrong, I already changed the graphic card, no result. In system profiler both displays are listed mostly, also in the display menue on the topbar, though as soon as I tell to recognize the displays only the main display remains. The 17" display has the extern power supply, but it´s a original apple as well. Thought it might be a bad contact, but can´t find anything. Living here in spain I nearly have no chance to check the display by a dealer. I would be grateful for some help, Michael.

Re: Equium L350-10L - first start with battery power supply

I have just bought an Equium L350-10L. When it arrived it was powered up using the battery and the Windows installation began. However the battery expired and I cannot get past the "unexpected shut down" message even after rebooting.
How can I get back to square one and restart the installation process? Advice.

Oh buddy, so silly idea. I really can not understand you. After weeks or maybe months in the box, it is logic that battery can not run with full capacity.
Anyway, connect your notebook to AC power supply and leave it for a while. Start notebook again to see what will happen. If the setup procedure can not be finished start notebook again and press F8 immediately. Chose first option Repair my Computer and follow the menu on the screen. The OS will be installed again and you will be able to finish OS setup procedure.

Auxiliary Battery Power Supply

Does anyone have a good source for an auxiliary battery-pack for my mobile Apple Devices such as the iPhone, iPad, an iTouch. I'm looking for one that doesn't plug-in to an electrical outlet either at home or in a car. Just a pure battery pack for my mobile iOS devices. I had one offered by Richard Solo online, but it wore-out quickly and then wouldn't retain or absorb any power after re-charging with an electrical outlet.
Thanks in advance.
Tony

I use a HyperJuice Mini when I travel. Works great. It fully charges an iPhone and gives about a 50% charge on an iPad2. Comes in cool colors too.

Satellite 2450-201 wont start with battery power supply

Can anyone please help, I cannot power up through the battery at all. When connecting the AC supply, the laptop powers up no problem. And after the intitial power up, I can switch to the battery without any problem. But it won't let me power up through the battery at all.
Can anyone advice, is there any settings that will help or do I need a new battery?

Hi
How about the battery charging status?
Is the battery fully charged?
Try to disconnect the AC adaptor and remove the battery from the notebook for a several time (15-30min) then plug the battery again and try to power up the notebook.
I think also you should check if the issue happens also with the new power pack. Possibly there is something wrong with the battery and you need a new one.
Sorry for such general suggestions but you know, we can only speculate about the issues.

My ipad power supply plug isnt working

When i charge my ipad i have to unplug and plug it back in again about. Ten times before it works and same thing when i plug it in to itunes on a mac

Try a different wall outlet to test.
If that didn't help, try a different cable and power adapter.
If you don't have a spare, might be time for a new one.
And try a reset ..
Tap Settings > General > Reset > Reset All Settings

Macbook powering off under battery power while still showing 20% remaining.

My Macbook is randomnly shutting down, even thought it shows anywhere from 20-25% remaining. I have tried to run the calibration, but I can never discharge my battery entirely as the computer shuts down before I ever get that far.
Anyone have any ideas?
System Profiler:
Charge Information:
Charge remaining (mAh):          972
Fully charged:          No
Charging:          Yes
Full charge capacity (mAh):          3265

Kabby,
Thanks for the quick reply. Does the system profiler look to you like it's actually at 0% I grabbed the data off the profiler as soon as I plugged in and restarted my computer, so it hasn't had the opportunity to charge or anything yet. The profiler should be representative of the system at the time of shutdown.
Is my battery possibly caput? Just trying to diagnose here before having to pay the geniuses to look at it, since the computer is 3-4 years old and out of warranty.

Power Supply is not working in Germany

Hi, I bought long time ago a notebook in USA. When I was back in Germany the notebook didn't charged any more. I asked for support, because of the guarantee, but they said there guarantee is for supplies only six month. I forgot the notebook in the cellar. Now I'm asking myself, if the is a possibility to get a "new" notebook running. I just used the notebook 2 hours. Thanks and regardsMosesKama P.S: I wouldn't recommend the service in Germany to somebody. I wrote them before months and I'm still waiting for a feedback.
