My laptop won't start without battery mounted

Hello! I have a Compaq CQ61-200sq laptop and recently my battery just got "old". So for the time untill i will buy a new one a just took it out and try to use the laptop without battery, just with the AC adaptor pluged in. But, just i said it won't start if i don't mount the battery. If i took the battery out while it's on there is no problem.
So, my question, beside what could be the problem, is if the problem will disapear with a new battery. I don't want to buy a new battery and still have problems.
Thank you!

I updated it about two to three times and would still experience the same problem.
Why update 3 times?!? If you run an update, and it installs normally, that it - done!
There's a world of difference between running BatteryUpdate 1.2 and installing a new battery. In fact, if you read the linked page above, it states that the after you run battery update if you experience any of the listed problems you should contact AppleCare. Their first step will be to replace the battery. Could it be a logic board problem? Sure. Is that the first thing they'll do? No. By that reasoning, the first thing to try if your car fails to start on a cold morning is to put in a new engine...
So, to the OP, contact Apple - or better yet, if it's convenient, go in to an Apple Store. Get a new battery. If the problem persists, go from there. The advantage of taking it into a Store is that they'll test it on the spot.

Laptop won't start without charger!! (battery fully charged but worthless)

My Macbook Pro won't turn on unless its plugged into the charger. If I turn it on without it being plugged in, it'll begin starting up, then immediatly shut down (the battery is fully charged). Does anyone know how to fix this problem? It's really getting me worried!!

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?

MacBook won't start on battery/shuts down when power adapter is removed

Help & advice needed please.
My MacBook won't start without external power, it gives a whir then a click then nothing. Once started up, if I remove the external power it just shuts off.
The battery shows at 98% & charging. Coconut Battery shows the following:
Current battery charge 4126 (& increasing as I type)
Maximum battery charge 4200
Current battery capacity 4200
Original battery capacity 5200
80%
Battery loadcycles 111
Age of your Mac 6 months
Charger connected yes
Battery is charging yes
Does anyone have a clue why the Mac won't power itself on the battery when everything else seems like it works?
Cheers!

As of today, my MacBook and I have been together for 40 days. Yesterday, while I was happily surfing (on battery), it powered down with no warning. Okay, these things happen. I plugged it in, restarted, and all seemed to be fine. Battery was about 70%. I did other things on my other machines and when it was about 90%, unplugged it and everything was good. This morning after using it unplugged for 1.5 hours it did the same thing, but decided to only work with the power adapter, not on battery alone. When trying to boot without AC, it would try to spin the CD and then fall back into off. When on AC, if I pulled the adapter, it would last two seconds and go blank. I made an appt. with the Apple store (Fashion Show Mall, Las Vegas) for 3:20pm. I got there right at 3:20pm and the monitors showed I was 5th in line. Store was fairly packed, at least one patron at every display item. Monitors also said the next MacGenius appt. was "approx. 8:30pm." Glad I made an appt! I was served about 15 min. later, during which time the monitors had changed to "No more MacGenius appts. available today, please try tomorrow." However, one guy came by without an appt. and was told he would be put on standby and to come back in 30 min.
Once I explained my issue with my MacBook battery, my Genius tried one of his batteries. "I just want to make sure it's your battery and not your motherboard." My machine worked fine, so he said "No problem, I'll have you out of here in 10 minutes." He got me a brand new battery, tested it, and put my old one in a box on the rear counter with four others. He pulled the serial number from the "About this Mac" area, didn't need my receipt for purchase date or anything. I had even printed this page: http://www.apple.com/support/macbook_macbookpro/batteryupdate/ to use as ammunition, but didn't need it. He did approve highly of my dashboard widget "iStat pro", available here: http://islayer.com/.
So the battery issue is a very common problem, and one that Apple has tried to deal with as painlessly as possible for the consumer. My Genius did ask if the battery showed an "X" in the icon bar, and I said no. Just wouldn't run on battery. On the way out of the store, one of the 3 MacBooks, in fact the one closest to the door, had an "X" on the battery icon. When I unplugged the power, it shut down immediately! The moral of the story is to contact Apple immediately with problems and give them a chance to fix them. Hope this helps others.

Sattelite L300D won't start on battery, needs adapter to start

Hi!
I've have my Sattelite L300D since April last year, and suddenly my laptop won't start when the net adapter is not connected. Battery says 100% (Fully loaded) when I'm connected, and started the system.
Anyone any idea why my laptop's not starting on battery alone?
I already updated the BIOS to version 1.50 but that does not change a thing!
(My warranty is till April, so should I send it in for repair?)
Thanks a lot in advance!

Hi!
In your case I would go to a local ASP (authorized service provider) and let check your laptop from these technicians.
I think its a hardware problem, maybe the battery is faulty and so you can only start the laptop with AC/DC adapter.
Bye

What can I do if my Windows 7 or Windows Vista laptop won't start?

I have joined many forums in my short computer life. This is by far the best forum that I have been a part of. It really up sets me when people come on here and complain before they have even given any of the staff or advisors a chance to help them with their problem.

This is a great tutorial. Step by step to get your PC up and running and a lot more.Seriosly, if you can't follow this tutorial, you shouldn't have a computer. There will times when this won't work and you will have hardware problems. There are some great people here on the forum that can help you find those problems also. I have tried all these recovery options; they work, and I love my Toshiba laptop. That's why I donate my time to help and that's why others here donate their time.

Hi!! You should try the recovery feature in W7. Some times it can be accessed through safe mode. On my model it's easier to use the system repair disc. You can find out how to create that here.

PS Some day I'm going to convince staff to make a sticky of these things; which would cut their work in half, but then I wouldn't have any thing to do.
Here's what the recovery looks like. You have 5 options to help you. The Dos option can really help if you are familiar with Dos. In Dos you can do a chkdsk---sfc /scannow--- and a whole lot more. Start with the Repair option first and work your way down.

Could macbook starts without battery by using adapter as power source!!??

Hi all
I have macbook black early 2008 model. My battery is damaged as it falls in water.
I have experienced that If the adapter is plugged with macbook and macbook is on and then i remove the battery ...its remain on...
My question is this that could macbook starts without battery using the power adapter as power source.
Thanks
Regards
Abdul Azeez

Yes it will start and run. The downside is your MacBook will run slower and if you accidentally pull out the plug it will shut off immediately and you'll lose any work that hasn't been saved. I suggest replacing the battery when you can.

IMac won't start without install disc

Hi, I'm new to all of this. I tried resetting my admin password using install disc on my iMac as I'd forgotten it. Now iMac won't start without disc. If disc is ejected on restart apple logo flashes between no entry sign and folder with "?" on it. Will start up with install disc in, but then wants me to choose language and install OS. Tried repairing and verifying HD and all seems ok. Tried holding option key and selecting HD on startup, but same outcome - choose language and install OS. How do I get back to normal desk top? Do I have to install OS again? Will I lose data? Please, please help! Thanks.

It should only take a minute or so at most to boot from the DVD.
If your sure you have the correct Install Disk for that iMac, I'd start over. Then if it still doesn't work then perhaps a trip to your Local Apple Service Provider with the Disk or Disk and iMac is in order.

Alternately using the correct Disk as per the following article, see if you can run the Apple Hardware Test? > http://support.apple.com/kb/HT1509

I have tried to update from Leopard to Snow Leopard using disk. New OS wouldn't load and now laptop won't start at all

I have tried to update from Leopard to Snow Leopard using disk. New OS wouldn't load and now laptop won't start at all. Simply get the Apple logo and the clock below and then after about 10 mins the laptop switched itself off. The Snow Leopard disk is a brand new family edition. Error message when attempting to install was that "this software cannot be installed on this disk".

Thanks Fred, but I've tried '''ALL''' that already.
I '''THINK''' I might have found the problem - the Profiles folder has been locked by inherited properties from the levels above. I have had to go all the way up to my User folder and reset ALL the properties from there down to be unlocked so that I could remove the prefs.js file so that it could be recreated on the next launch of FF. Exactly why my User folder is locked in such a way as to stop me/FF making changes when I have been able to alter preferences at will in the past, I don't know ...
So far, so good. I have since done a complete shutdown and when I restarted this morning, FF seems to be behaving itself ...

My laptop won't start up, I want to back it up via firewire, but it is filevault protected. How do I login and turn off vilevault?

My laptop won't start up, I want to back it up via firewire, but it is filevault protected. How do I login and turn off vilevault? When I connect to another computer via firewire and try to transfer files, finder freezes.

To use FireWire target disk mode
Make sure that the target computer is turned off.
If you are using an Apple portable computer such as a PowerBook or MacBook as the target computer, plug in its AC power adapter.
Use a FireWire cable to connect the target computer to a host computer. The host computer can be powered on.
Start up the target computer and immediately press and hold down the T key until the FireWire icon appears. The hard disk of the target computer should become available to the host computer and will likely appear on desktop. (If the target computer is running Mac OS X v10.4 Tiger, you can also open System Preferences, choose Startup Disk, and click Target Disk Mode. Restart the computer and it will start up in Target Disk Mode.)
When you are finished copying files, locate the target computer's hard disk icon on the desktop of the host computer and drag it to the Trash or choose Eject (or Put Away) from the File menu.
Press the target computer's power button to turn it off.
Unplug the FireWire cable.

T21 won't start on battery only. Starts OK with charger, which can then be disconnected!

My Thinkpad T21 will not start on battery only. Indicators turn green (ventilator and disc try to run) for only less than a second and nothing more. If a charger/adapter is connected the machine starts OK, and then I even can disconnect the charger and continue to work. I only see a slight decrease in backlight intensity. This started after I connected a defective charger to the computer . I'm afraid some FET switch 'died'. I've found elsewhere suggestions to discharge a certain "overcharged capacitor" and tried it by disconnecting the battery and pressing the ON button continuously then repeatedly but without results. According to the service manual I should replace the main board, but before I do that I'm ready to benefit from my possibility to access SMD repair tools. I've nothing to loose. Does anyone know the startup circuitry or point me to the possibly bad FET? Does anyone have the keyboard circuit or at least the connector's pin designations (or at the very least: which pins are wired to the POWER button)? Thanks, ANTIK

Repeating my response to your thread at TPF in case you (or anyone else hasn't seen it):
It does sound possible that one (or more) of the MOSFETs on the motherboard has died. As far as we know, there are no schematic diagrams publicly available for any Thinkpad. Assuming that you want/need to know the pinout designation for the keyboard connector in order to turn on the laptop without the keyboard attached, then you can use the simple port replicator (FRU 02K8668) to do that. Mount the laptop in the port replicator (without the keyboard) and you can then press the power button on the replicator to turn on the system. These port replicators are available on eBay, like this one:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=350196508319
There may be cheaper sources on eBay or locally.

Lenovo G510 won't start when battery is on and it's fully charged

Hi there. I have my Lenovo g510 i5 notebook for 10 months, and my battery is wrong. I haven't used it on battery too much, but when I used it, I empty all of it and then charged it when it's turned down. Couple of days ago, the battery was empty I put it to charge, the orange light appears that it's charging, and day after when I put the battery on the notebook won't start, but with the battery and adapter start normally and show that the battery is 100% (fully charged). Why I can't use it on battery? Please help me.

Hi Kocevski_91,
Welcome to Lenovo Community!
As per the query we understood that you are facing issue with system not starting with battery in your G510 laptop.
Please remove the battery and connect only adapter and check for the issue, also try to perform a power drain by removing all the external devices connected to the devices and shutdown the system, now remove battery and adapter, press and hold the power button for 30 seconds, connect battery and adapter and check for the issue.
If still the issue persist, perform battery gauge reset, go to power manager select advance mode and select battery tab and click on battery maintenance under this option click perform under battery gauge option. Please perform and reply with results.
Hope this helps. Do post back if issue persists!
Best regards,
Ashwin.S
