Lenovo s10e won't start on battery power alone

Hi,
I have the following problem with my Lenovo s10e netbook:
On battery power, press the power button, I see a flash on the screen, the blue power led turns on, then off after a few seconds, I can hear a sound from inside the device but it does not turn on.
If I connect the power adapter with the battery connected the device starts up with no problem.
If the battery is not connected and I only use the power adapter I have no problem starting the device.
I tried using a different battery and still have the same issue.
Do you have any idea what is causing this?

hi icelexy,
Welcome to the Lenovo Forums.
The unit looks like it's not getting enough power on the battery. If you're using the original 6 cell, 4400 mAh. 11.1 V battery, there's most likely a problem on the charging mechanism at the back part of the unit.
Have you already contacted lenovo to report the issue? (they'll most likely ask you to send the unit in for diagnosis)
Regards,
neokenchi

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

Macbook won't start on battery power

I have a six-week old Macbook. Was working just fine until today.
Now it will not boot up on battery power. Works fine when Magsafe is connected and the battery is showing that it's fully charged (100%). When disconnected from AC power it powers off immediately and won't boot up.
Have tried a SMC reset. Didn't help. Any guesses what the problem might be?
Thanks in advance.

Currently, there are two very similar problems with the MacBook batteries, I've found.
The first is that the computer IS recognizing that the battery is there, and the MacBook shuts down almost as soon as AC power is removed. The usual diagnosis here is that you have a bad battery.
The second variant is that the computer is NOT recognizing that the battery is there (the X through the battery literally means the computer thinks you have no battery connected), and the omputer behaves he same way as the one in the first scenario. This usualy means that you have another type of bad battery, or the battery does not have a full connection.
Either way, I reccomend that you follow these steps:
1. test the battery by pushing the small button next to the set of LEDs on the battery pack, and make sure the LEDs light up. If they do not, the battery is most likely deffective.
2. Make sure there is no foreign object or corrosion causing a bad connection with the battery. You should be ably to do this by removing the battery and looking at the metal contacts on both the battery and computer.
3. Make sure your software and firmware are updated. To do this, click the apple pull-down menu in the top left corner of the sceen, and select "About this mac". Then, click the Software Update button.
4. Reset the PRAM, PMU, SMC, and make sure the battery is properly installed. Find instructions on Apple's website.
If all else fails (or if the battery proves to b defective in step 1), call Apple or visit an Apple store to get tested, and replacements.
I hope this helped. Nobody bothered to answer my post, and I had to find this information out from a buddy of mine.

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.

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?

PB won't start, has no power, won't charge BUT I NEED THE INFO desperately

Hello! As the subject states, it won't start, has NoOoOoOo power, cannot get it to charge (and it's been plugged in now for 2.5 days). While RIM CS said they might fix it, I need to get the information off the tab first as it's REALLY really REALLY important.
I did post in another thread, but it seems my issue is just a little more challenging that most, as I've tried ALL the "ideas" that I have come across - here and in other site forums. If only it were as easy as the pins being bent or getting another charger.....
So not only will mine NOT start up, and is COMPLETELY dead, but (and here's the fun part) the USB port has been busted since purchase. (Thought we'd manage without, but hah....)
- the battery was NOT fully depleted when it crashed as it does every second day (this was Friday)
- have a Rapid Charger, and have been using it all along
- it has been plugged in for DAYS and nothing IS happening; no lights whatsoever
NO light red, yellow, green, or otherwise that comes on when plugged in (or otherwise)
- Looks like this "stacking" that keeps coming up refers only to when plugged into computers, which I cannot do,
though I did try the 2 min interval anyhow for awhile
- I DID hold down the power button for 10, 20, 30 seconds per notes on these boards
- I DID hold down the power button for 2 whole minutes even per some suggestion
- I DID try the power button with Volume + then with both volumes and power all at once
- In fact, if anyone anywhere wrote to jump up on one foot, I tried that too!
AND the reason it matters . . . there are photos or someone who has passed away on there that I need to get off before sending for repair (or better yet replacement if there are any left anywhere) and really need to get this thing started again. Been a long time that I've been trying to get these images off, though I think that's another discussion for when it gets started hm...)
Anything, oh wise BB PB peeps??
Thanks in advance!!

chaosdivine thanks for the idea!
Had to laugh at the comment that the USB would be wobbly after some time had gone by. Mine was broken after first attempt to even use it!
Anyhow, good post, but did all that already. Plugged in and sit, plug and unplug, plug and try to turn it on, leave it off, etc. and then some etc.

Mac Book Pro will not start on Battery Power

Mac Book Pro will not start on Battery Power although battery at 98% need to connect charger. When started date and time incorrect, comes up as 1st Jan 2012.

What is the exact model of your MBP? The date change often is an indication of power loss to the MBP, such as disconnecting the battery.
If the SMC reset does not solve the situation, post this from your MBP:
Make certain that the power adapter is connected.
Ciao.

Battery power alone can be used to track Android phones

Now our phones can be tracked without GPS can you believe it ?
BBC News - Battery power alone can be used to track Android phones

     I'm trying to do the same thing, and have had limited success with an app called Control Plane. Please understand that I am pretty computer illiterate so this may not be the best way, or even a good way to accomplish this.   http://www.controlplaneapp.com/
     It allows you to automatically toggle bluetooth(and many other aspects) on or off under certain contexts. I tried setting it up to detect the display connection but sometimes it would detect the display, and sometimes it wouldn't. So I set it up to detect the specific power adapter for the display. So when I plug the monitor power adapter in it switches to the context i labeled "monitor" and I set an action to toggle bluetooth on under this context, when I unplug the power adapter it switches to a context I've named "battery" and turns the bluetooth off.
     Automatically turning the bluetooth on is specific to only connecting the monitor power adapter, when other power adapters are connected it does not turn bluetooth on. But it is limited in the fact that if I have bluetooth on in instances other than the monitor connection, and then disconnect any power adapter, it will automatically turn the bluetooth off.
     Also if my computer is in clamshell mode, and therefore asleep, when I plug the monitor+power adapter in it doesn't automatically turn on bluetooth, and I cannot use my bluetooth keyboard or trackpad to wake the computer. This forces me to open the computer momentarily to allow it to wake up and control panel to turn on bluetooth for me.
     Since my main issue was that I didn't want bluetooth on constantly to save battery life, this works for me, but it is not ideal. Ideally connecting the monitor to the computer in clamshell mode would wake it from sleep, but as of now I can't figure out how to make it do that. If you have any suggestions on how to make this process more efficient please let me know. Hope this helped.

SatelliteU300 Won't start with AC power connected and fully charged battery

I just bought a U300-13U. It works great when battery is charging and AC is connected. However if left to charge up fully it won't start with AC connected. Unpluging the power or removing the battery and running on AC makes it work fine. Is this a 'feature' to stop overcharging or overheating the battery, or just a problem with this machine. I want to run with AC and battery both connected all the time as I have done with all my other laptops.
Any help appreciated.

Hello Andy
Friend of mine has this small U300 and everything work well. I have had it few weeks ago to test WXp installation and it works perfectly.
Please test it again very carefully and if the same happen again I recommend you to contact Authorized service partner in your country. Let them check your notebook. I must be honest and say that described issue sounds strange to me and please do not wait too long. Contact service as soon as possible.
Bye and good luck!

Computer won't start with battery in it...

have an Aluminum 15" Powerbook G4. I have had this since 2001, when I bought it. I recently updated to OSX. I hadn't used the computer in months and when I went to try and take care of the computer and update to OS 10.4.5 I encountered a problem. When I turned it on nothing happened. I had to turn it off, hit the reset button and then plug in the computer. THe battery was dead so I expected that. But what happened next puzzled me and still does puzzle me.
I managed to get the computer on by holding in the power button. I heard the familiar start up sound(the sound splash if you will) and when that ended I heard this incredibly loud, white noise coming from my speaker. The noise occured about four times. I was in the room with my wife and mother and they both looked at me like 'what the heck was that?"
Now I thought maybe this was an issue with my one battery so I uncovered my second battery and the same thing happened. It won't start up with a battery in there. I took the battery out and found that when it seemed to turn on just fine, I managed to get online and run a complete update. When it came time for the software required restart the computer started up and didn't make any noise at all.
I guess I don't know what to do now. I ran the diagnostics on the computer, from the disk utility and it seemed to come up clean. I don't mind not having the battery in the computer but I don't always want to fix the date and time and the like.
THis is why I'm posting.
I also noticed tonight, when I was charging up the battery that I had to stop and take it with me someplace. When I went to turn it back on, with the battery in and it plugged in the noise came back on and I had to fix the date and time again.
Thanks to those who post, I really appreciate it.

not sure if this will solve your problem but you can try..
look at the battery exchange program if your battery is eligable for the replacement or take it to the local dealer so they can check if your board sound is ok.

Laptop won't start quickly but power wifi and caps lock light keeps blinking

Hi, it has happened before too but rarely but nowadays it happens on daily purposes.
When I switch on my laptop after leaving it for 8-9 hrs, it won't start up but instead power, wifi and caps lock light keep blinking. I tried removing battery and pressing power button for few minutes but nothing happens. Then i left it like that with lights blinking and after 15 20 minutes it booted. I did same yesterday too. I left it like that it booted after 20 minutes..so My question is "why is this happening? Is it a motherboard issue or is it because of cold moisturous weather here and laptop takes time to get warm up?" Should I show it to HP Service center?

Hi @Nishant5788
Welcome to the HP Support Forums. I see that you are having a problem getting your notebook to boot up normally. As for what is causing the problem the blinking Caps Lock should tell us what is causing the problem as it should be blinking in a pattern. This HP document Computer Does Not Start and LEDs blink has a chart that will tell you what the blink codes mean.
This is most likely a hardware issue and you can give us a call regarding repair options. You can reach HP Total Care at 1-800-474-6836 in North America or start here if you live outside of North America.

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:

There may be cheaper sources on eBay or locally.

Qosmio X500 won't start and the power LED is blinks every 5 seconds

Hi,
I need help my X500 won't start now. I tried to start the NB as usual and suddenly the X500 wont boot or even power up.
If I press power button it doesnt make any sound, the power LED on button and the second power LED just bliks once and turns of, and keep blinking every 5 seconds.
I tried to:
* remove battery and power up with AC only
* power with battery only
* remove battery hold power button for 30 seconds and more athen power with AC only, battery only
but it didn't helped.
I checked the AC & Battery LEDs, but they are not flashing, they are just RED, so there is not proble in battery or AC.
Any idea where could be the problem?
Thanks for help
