Lenovo won't turn on with battery, without battery turn on!

Q: Lenovo won't turn on with battery, without battery turn on!

Hi!

I have lenovo ideapad g585gc 59-356202 e1-1200, dvdrw, 4gb, 500gb, radeon hd 7310m, 15.6" led, ....
Almost 2 years old.
Yesterday it didn't want to turn on, and then I took out the battery and try without it and then turned on and everything is ok.

So,
1. with battery (with or without ac power) won't turn on
2. without battery (of course, with ac power) turn on

The problem is evidently in the battery. I want to buy a new one, but how can I be sure that the battery is really dead?

Preferred Solution: Lenovo won't turn on with battery, without battery turn on!

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Lenovo won't turn on with battery, without battery turn on!

There are no good practical ways the average owner can test the battery. You have to go on the evidence.

My laptop is not charging when it is turned on. I use Ubuntu 17.10 and Windows 10. Battery only charges when laptop is turned off.Also when I try to turn on my laptop without battery, it turns on for 1-2 seconds and suddenly sutts off, (and it does not boot). Changed power jack but same thing. Also tried another AC adapter. Even computer master cannot find a problem.I guess the problem is with motherboard, but cannot find which part is not working. Who had such problem and how have you solved it?

Hello, As the Title suggests, I am not able to turn on my Lenovo Yoga 2 13.When I try to turn on the Laptop, the White Light on the power button comes up for 6 Seconds and then goes off. Keyboard lights do not turn on, & the same effect with pressing the Novo recovery key.The battery does charge (The lights change according to the charge levels.) Things that I have tried so far: 1) Remove the power cable and press the power button for 30 Seconds, 60 Seconds, & 90 Seconds. No Effect. 2) Open up the backside, remove the battery cable (and battery), remove the power cable, and power discharge by pressing the power button. Turn on the laptop using just the Power cable. No Effect. 3) Remove the heatsink, clean it and then reapply the Thermal paste. No Effect. 4) Remove the hard disk and then try turning on. No Effect.  Despite trying all these steps, the effect is still the same. I honestly do not ahve any idea what to do now. Can anyone suggest something?  Any help would be appreciated!Thank You!

Hello Lenovo Community!I own an Ideappad Z400 Touch and I had issues with trying to charge it. Obviously I turned to the forums here and I found a possible solution here. When I tried to perform a battery firmware update, it went smoothly and then suddenly turned off and had a fast flashing orange light. Obviously I knew my battery and/or charger let me down in the middle of the process. I'm kind of scared because I don't know what to do nor have the money to afford a new laptop. What most likely happened to the battery is that it got "electronically disconnected" and technically only relies on the AC adapter which now I have found out is pretty screwed up and stops charging once Windows actually boots up. Is there any way to fix this? Please help! Thank you and have a wonderful evening!

If you have a normal warranty, the battery is covered for a year.  I suggest calling support. In U.S. the number is 1-800-426-7378

A:My hp 250 g4 won't turn on with the battery

Does the battery charge when the notebook is not turned on?That is the critical bit. If the battery does not have enough charge, it certainly won't be able to supply enough power to boot the notebook.  How long have you had the notebook? If it has been a year or more, the battery might no longer be serviceable.

Hi,

I bought a new battery for my Sony Vaio (VGP-BPL9) about 2 months ago. It worked for a while, but all of a sudden my laptop would not turn on with my battery in there.

The battery is fine, it's new. How can I fix this?
 

A:Laptop will not turn on with battery

It could be that the Charger can no longer handle chrging the battery and running the laptop at the same time. But how have you confirmed that the battery is good? Just because it is only 2 months old? Or has it been tested in another compatible laptop to confirm this. Also did you buy this battery from Sony or some where else?

If I unplug the adapter the screen dims, so I assume the adapter is working.

I've got an older Dell Latitude that I've turned into something of a netbook. It has to only have a 4 cell battery because it only last's an hour and a half give or take 15 minutes (depending on brightness).

How much battery life can I save by disabling Wi-fi? I don't have just a switch on the side of the laptop that I can turn off/on. By disabling it, I would go into Network Connections and right click on my wireless connection and disable it there? Would that save any battery life?

Hi, my laptop (HP ProBook 450 G0) won't turn on without the AC adapter although the battery is charged (97%). When the adapter isn't plugged in, the adapter/battery LED (on the left side of the laptop) is flashing really fast (like 20times per sec). When I press the power button, nothing happens. When the adapter is plugged in, I can turn the laptop on. The adapter/battery LED is off, Windows say "plugged in, not charging". I ran battery test and system hardware test and everything's OK.

Turn it off again and again it will not power up. If I leave the CMOS battery unplugged, then I can restart the machine, but only after I unplug the power cord and plug it back in; kind of like a reset between each poweroff/power on cycle. If laptop battery is inserted, it will not power on no matter what I do. It will only power on with the power cord. Laptop Battery checks out fine. I tried a new CMOS battery as well.Solution???

I would encourage you calling in technical support for inwarranty repair.
The hardware manual here do offer power checkout guide (page 21-22) to help isolate the ac charger but since it can charge the battery from purple to white, then internal parts should be checked further.
 
I hope this helps you on how to proceed.

Last week the fuses in my bedroom suddenly blew. At the same time I heard a loud crack and the smell of burning and smoke. Nothing was on fire so I thought it was something in the wall. I checked the fuses, turned them all back on and everything was fine. I went back to my computer, finished with it and turned it to sleep mode. When I woke up the next day it wouldn't turn on again. Everytime I press the power button I see the light by the plug flash 3 times. I've looked this up and tried removing the battery, draining it of electricity... I've tried everything but I only get those 3 flashes. Have I maybe broken the charger and has my laptop drained of electricity? I can't think of anything else, but that the burning smell might have been from the charger. Can I check this somehow?

When I disconnect the mains, the laptop immediately turns off and doesn?t swap to battery mode. When trying to turn the laptop on with just battery power, the laptop does not turn on. However, I can hear a high pitch noise every time the power button is pressed in this situation. I have attempted this with three different batteries. At the moment I have my machine dissembled trying to work out if there a short from one of the circuits that connect to the battery. If anyone has had this problem or knows anyone or anywhere to fix it, please advise me. Also if anyone knows where or if there are any circuit layout diagrams of the motherboard that will also be a great help as I can see if any of the components are shorted or burnt out. ThanksMcMillan1810

When you plug the power lead into the laptop, the battery light is lit but when you try to turn the laptop on it goes off- there's also a small clicking sound each time I try to turn it on. I've tried running the laptop without the battery and still no success. Also if you leave the power lead in the battery light goes off within a minute...I'm absolutly stuck with what to try next- I've used compressed air etc to try and clean everything out...still nudda.

A:Laptop wont turn on- dead battery?

Sounds like a failed HardDrive (if it is you will need it replaced)

Just in case though:

Remove all power (battery and adaptor)
Hold down the power ON button for 30secs (dispersing all internal voltage)
Plug the power adaptor in only (for the moment)
Turn on

If it still doesn't work, I think the HardDrive has gone (ie clicking noise)

However, the battery wasn't being recognized by the laptop. I didn't have time to deal with it then so i just left it, but now I've come back to it a few hours later, and the laptop will not turn on at all.Even connected with my charger, all the laptop does is flash the power indicator light 3 times.
