Z510 automatically shuts down at 99% battery, when running on battery

My Lenovo IdeaPad Z510 shuts down after 30-40 minutes when running on battery, without any notification. The battery level displays 99% battery.I've tried various troubleshooting steps, including gauge reset, charging for 10 hours when shut down, charging couple of times in BIOS mode. The energy manager says battery health is "normal". Battery report says :DESIGN CAPACITY43,200 mWhFULL CHARGE CAPACITY48,000 mWh My laptop is under warranty, but service center has refused to replace battery because report says it's healthy. Kindly provide some solution.

If the battery says its health is fine, it seems to me like its an issue with the motherboard. I'm not really sure how you'd go about checking that though especially since the service center won't let you send your laptop in. Might have to wait for someone else who knows more about it than me, sorry .

Automatically shutting down at 20% battery

I've recently experienced this twice. The first time I didn't really look much into it because I thought it was an isolated incident. But today, it happened again. I was in a lecture, and the lecture hall had no powerplugs, so I had to use the battery for an hour or so. So, the battery reaches 20%, and it just shuts down on me. Is there a major problem? Shouldn't the battery at least get to 1% or 2% before shutting itself down?
My MacBook has had problems before, changed the heatsink, and replaced a battery (didn't detect). I hope this isn't another problem because my warranty ran out last month.
Thanks.

Have you done the battery update? About Battery Update 1.2.
I had this happen to me but at 23%. Apple replaced my battery with no problem. If your MacBook is the original core duo which it sounds as it is then you are in luck. The battery for the original has had it's warranty extended an extra year. Even if you MacBook warranty is dead the batteries isn't. If the update doesn't work contact Apple at the number listed in the update.
One point is be firm but polite. I had no problems getting mine but others have had to argue some to get the battery replaced.

When I start iTunes on my home computer (Not a MAC), it automatically shuts down, and gives me the message that the Data Execution Prevention security feature has shut it down...what to do?

When I start iTunes on my home computer (Not a MAC), it automatically shuts down, and gives me the message that the Data Execution Prevention security feature has shut it down...what to do?

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it, which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

my ipad automatically shut down and now i lost al savings and in-app purchases the battery was on 50% what happened and can i get my purchases back

Hi there,
This seems very frustrating. An iPad can shut down randomally for many reasons, just like a computer can crash. If it begins to happen regularly, then do contact Apple, but there are no signs that your iPad is malfunctioning from just one shut down like this.
But, you should be able to get all your in-app purchases back. In some apps, there is a 'restore purchases' button, which will download all the purchases you made for free.
In some cases, you can tap to make the purchase again, and it will be downloaded at no charge, however this does not happen with consumable items such as coins and credits.
I reccomend contacting iTunes Store Support at the link below, they will take a closer look at your purchases and give you further steps on redeeming them. They may also refund you if they have been lost.
iTunes Store Support
You can also contact the developer of the app, and report the crash and missing purchases. If you tell me the app, I'll give you the relevent contact in the developers.
Other than that, sorry for the problems, and have a great day,
Nathan

You probably need to restore your iPad now. Pay attention to the last part of this kb article where it explains about using recovery mode. You may need to restore the iPad using that method.

EEM -automatic shut down or switch over of WAN link in OSPF when packet drop increase

Hi,
Need help..
can any one help me how can EEM help for automatic shut down or switch over of WAN link in OSPF when packet drop increase a predefined level.
I have a set up different branches connected together...OSPF is the routing protocol and need to communicate with two branches via hub locations.
need to shut or switch some percent of traffic from primary to back up when packet drop in the link.

I am not sure EEM can do what you want.
Another option could be to use SLA tacking/monitoring. But you will fall back to the new route when you lose some percentage of pings, you can't switch only part of the traffic.
I hope it helps.

I usually remove my earphones and shut down the nano. When I attached the earphones it automatically turns on. Any solution?

You have 10.6 on that machine, I suggest you stick with it for performance, third party hardware and software reasons as long as possible.
Consider 10.8 (not 10.7) when it's released, because 10.7 and 10.8 will require a new investment in software and newer third party hardware as it requires newer drivers the old machines won't have. (forced upgrade because of software, really nice of them)

1: Software Update fully under the Apple menu.
2: Check the status of your plug-ins and update (works for all browsers) also install Firefox and see if your problems continue. You should always have at least two browsers on the machine just in case one fails.

No it doesn't, you would need an external download manager to get a feature like that.

Computer automatically shut down when Nano is connected

Whenever I connect my iPod Nano 4gb to my computer, my computer automatically shuts down. Just like that. Without any warning. Sometimes iTunes has the time to open, but most of the time it doesn't. Can someone please tell me what must I do? My nano has been working well for the past year.

Hello urrein, Did you enter the BIOS and set the day, time, and year after you replaced the CMOS battery on the motherboard?

Powerbook 17" G4 automatically shuts down in sleep mode

Powerbook 17" G4 automatically shuts down in sleep mode intermittently. When press power button to bring it back up, it takes a very long time to reboot and the date is set to Dec 31, 1969. It comes back up finally, but this is irritating.
Thanks for any help,

Hi Reaskt
Have you tried using Temperture Monitor to monitor your temps? Maybe it is overheating. Also it sounds like your backup battery is dead, that's why the clock reset's it's self. If you still have applecare I would give apple a call a soon I could. To me it looks like you would need a new logic board. I realy hope that you have applecare. Also have you tried an Erase and Install? Have you tried running Disk Utility booted from your install CD?
Post back when you get more info

Compaq Presario CQ60, overheating and automatically shutting down.

Hi.
I have a Compaq Presario CQ60 that is about a year old. These days I have been experiencing problems with my laptop. The problem is that the top hand corner gets hot, and then my laptop automatically shuts down itself. There is plenty of battery on my laptop, and it also happens, while my charger is plugged into it. This mainly happens when I am at school, where I do not bring my notebook fan cooler. I can basically do nothing, because every 30 minutes it will automatically shut down itself. It even happens when I am in "Battery save" mode. This is starting to irrate me, because I have only had this laptop for about a year, and my warranty just expired so there isn't much I could do. I have read about this being a problem to a lot of people...
I am wondering if it has something to do with my battery, because it is really bad. It only lasts for about 30 minutes from 100% to 10%. I do not know what the problem is, because I have no expertise in laptops.
I hope you can help me.

HI;
The easiest thing to do is to spray canned air into the vents by the fan and heat sink. If a lot of dust comes out, that will probably take care of the issue. If no dust comes out, then you have other issues causing overheating and thermal shutdown. Take care not to overspin the fan blades when you blow the air into it.

IPhone automatically shuts down.

My iPhone is currently updated to 4.3.5 but i have this problem that when ever i use an app at battery percentage of below 80%, my iPhone will automatically shut down and display the no battery sign. But after about 5mins when i start my iphone again, it will be left with 50+% battery. This problem has already happened for almost 1 month but there seem to be nothing i could do to solve it, it is very annoying as i cannot do anything except to listen to music after my battery percentage drops below 80%. And that my iPhone charging time seems to be much slower, my mum takes the same time to charge her iPhone from 18% to 100% with me charging my iPhone from 75% to 100%, my battery percentage also decreases much faster than hers. Can anyone tell me what to do with my iPhone??
