Solved: battery indicator light flashing red when power button on my laptop is pushed

Q: Solved: battery indicator light flashing red when power button on my laptop is pushed

I just received my replacment AC adaptor. I put my battery back in and plugged the laptop in, but when i push the power button the battery indicator light flashes red four times. There are no lights on. Does this mean my battery is fried. Originally i thought the jack needed replaced, but the guy told me it was just my cord which Best Buy confirmed. So after getting the new cord i have this new problem. Usally there is a battery indicator light on when the battery is in and it is plugged in. I tryed taking out the battery, unplugging it and holding the power button down, but that didnt work. I also tryed it without the battery in. Is my battery just bad? Thanks for any help.

Thank you,

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.)

Try plugging the laptop in and then push the power button. I have had the same thing happen to me when the laptop would only work when I had it plugged in. I had to replace the battery.

Hi, I've got a Dell XPS M1530 laptop, and I just noticed today that the battery indicator light on the front of my laptop is blue for a few seconds, then flashes red, then back to blue, etc. I checked my battery's health and it says that it's able to charge normally, but my long-term battery life is decreasing. Also, it does not shut off right away with I unplug it; I left it out for a few minutes and it was still at 100%.

Should I just take this as a general warning to maybe order a battery sometime in the near future? Or is it blinking red for some other reason?


A:Battery indicator light flashing red...

Yes red lights on the battery indicator is a bad thing. If the laptop is under 1 year old and you have the warranty on the machine you can get it replaced under warranty if not you have to buy a replacement.

I am assuming you have unseated and reseated the battery with it keeping the same error lights? You may want to try that first since I have had times in the past this would clear errors.

My laptop has been distrubing since yesterday. Whenever I put in the power chord, the power light and battery light starts flashing together and the laptop does not charge. When I remove the chord, the flashing disapperas. Occassionally, it charges a little before going out again.  I tried using the laptop without the battery. It sometimes does not start and other times, it goes into the first few seconds of booting (the BIOS page) before going out again.  Do you guys know what this code indicates? Any help would be appreciated. Thanks!

This just started happening recently. The power indicator light (near the power plug) does not turn on and Windows does not recognize when the adapter is plugged in; the power icon and cusomized power saving "on battery" behavior reflect that. HOWEVER, the battery does charge. The "lightning bolt" charging light on the front between HDD and system power lights comes on and the battery recharges if not at 100%. Any thoughts on how to troubleshoot this? Is it more likely a Windows or hardware problem? The BIOS does not have the power adapter test mentioned here, and I could not find the software download for the Smart Adapter functionality (this laptop was installed with clean, non-OEM OS, so any OEM software had to be added manually). Thanks in advance,Kyle

Just a week ago my thinkpad T430 had refused to start after I had swapped out a battery.Just on battery power the laptop is completely powerless, holding the power does nothing, there is no indication of power as far as i can tell, nothing. When plugging in, the only sign of light is the battery indicator, there isn't anything else. Holding to the power does nothing.The battery LED pulses 2 short 1 long 1 short, stops and repeats. What can I do to fix this? Do I need a new FRU (motherboard), can I replace the motherboard for one with dedicated graphics without compatability issues?Can soldering fix the issue?

Hello everyone,  I am facing this problem from the past few days in my Lenovo G510. Whenever I plug in the charger for charging the laptop, both the power light and the battery light with orange color, starts flashing and the laptop stops charging.  The color of the battery light changes to orange, even if my laptop is nearly 50% charged.Can't figure out, what is the problem? Any help will be appreciated!

I have a Porterge R500 with Windows Vista from my work.

I was going on a trip so I got myself an extra battery.
Before taking the airplane everything worked fine. Both batteries worked and they were fully charged.

After I entered the airplane, out of the blue, the laptop didn't not start with neither of the two batteries (original both of them).

When I landed I connected it to the ac plug in, and it started. It says the battery is charging (70% and 80% respectively) but none of them seem to work because if I remove the plug in, the laptop shuts down.

When it is connected, the battery light does a sort of blinking (every now and then) but I don't understand what is the problem at all because the computer is working, I have two batteries going sort of dead at the same moment and even when they are charged according to the computer, they don't deliver the power.

Any hints?

A:Portege R500 does not run at battery power - indicator flashing amber

> After I entered the airplane, out of the blue, the laptop didn't not start with neither of the two batteries (original both of them).

Very strange that both batteries don?t work after you entered the airplane.
To be honest I?m not the expert on this area but maybe the radiation while checking the bags and personal items could affect the batteries.

However, fact is that notebook does not work using the batteries. I would recommend you to purchase another battery.

Hi Lenovo4g510i5,
Welcome to the Forums  
As per the query we understood that you are facing issue with power in your Lenovo G510 laptop.
Perform the power drain, to perform please disconnect all the external devices connected to the system shut down the machine and remove battery and adapter. Now press and hold the power button for 20 seconds. Now connect the battery and turn on the system and check for the issue.
This is to drain the static charge as the LED might be due to the static charge.
Best regards,

Hello! I recently decided to dig up my old Lenovo Ideapad Y410p, and to my surpise, it had been dropped before without my knowledge. I proceeded to attempt to plug in my PWR+ I7 replacement charger, and to my surpise the power button had lit up (the one on the palmrest/keyboard's surrounding area), and the power indicator (this one was white) and the battery indicator (this one was amber) were on aswell! I saw no signs of life from the screen, nor did I hear my fan, hard drive, or etc.. turn on as I tried to turn on my Ideapad. Furthermore, I tried using the Novo button, and used several reccomended methods of pressing the power button with and without the battery and/or charger, I don't know whats wrong with my laptop! I am capable of assembling and disassembling the system, as I have done it before, but what should I do in this case?

The battery light on my Latitude 7370 started to flash in orange and the laptop is not using the battery. It does not start when the AC is not plugged, and shuts down immediately after the AC is unplugged. However, the Dell online diagnostic test for battery passes it as working OK (the test for motherboards also passes). In BIOS, I can see the battery as 100% charged; however it also says "Health: Communication Error". A week ago the battery still had enough charge for up to 5 hours of office work. I have tried to unplug the battery, start the laptop without it, and then plug the battery back. I have also tried unplugging and plugging back the CMOS battery. Neither of these helped at all. I have been using the laptop with WD15. The behavior persists on 2 different WD15 units as well as on the default AC charger.

Hi. Tonight I had a problem with my laptop. It was in sleeping mode, and when I open the lid there were no mouse function and no touch screen function. So the only thing I could do was to press the power button for 3 seconds to turn it off, but it didn't completely, because the screen turn off, but the power button light is blinking just like when it is on sleep mode, and I'm not sure if the hard drive light was on, off or blinking before this, but now is blinking. I press the power button and nothing happen, I press it for 3 seconds and nothing happen. I even did the HDMI connection to another monitor, but both monitors don't show anything, not even recognize that something is connected to the HDMI port in the new monitor. There is no sound, nothing, just the 2 blinking lights. What should I do? Thanks PS: I'm not sure if it's Windows 10 32-bit or 64-bit. It was upgraded from Windows 8

Last night we had storms in Okla City during which I had an emergency and left home leaving my pc on - which I normally don't do. When I returned home several hours later, my pc was off and the power button was "dead". I checked all the obvious things, like checking the power strip, checking if the power cord was connected, and went to bed thinking "new pc" time (this one is 4 years old). However, this morning, on another pc, I found the video below - how simple it was to fix my pc. I just unplugged the power source at the back of the pc, punched the power button on the front for about 15 seconds, re-plugged the power cord at the back, and walla - when I punched the power button on the front again, the pc booted up! Just wanted to share with other users - considering this is the time of year for storms, lightning, etc. Needless to say, I am a happy camper this morning. Hope it helps someone else

Good evening guys. So I have a Lenovo B50-80 laptop. When the laptop is on and I plug in the charger, after a few seconds, the power button light (color green) begins to blink, the indicator light also next to the hardware indicator light becomes orange instantly (orange means it's low) and also begins to blink.  This happens only when the charger is plugged in. When it is out, the blinking stops totally. The blinking never stops when the charger is connected until it is removed.  I only get to charge it when the laptop is shut down.Please really need a fix for this. The battery is okay.

My PC wouldn't turn on on Monday night - just a green flashing light on the front. After a bid of fiddling with the kettle lead etc and moving the pc, it worked. After switching off as usual the same thing happened the next night. I replaced the kettle lead but now it just sits with the green light flashing. I've checked the forums but can't find someone with the same problem in that the pc DOES work every now and again. PC about 15 months old. Has anyone any suggestions (hoping its not the hard drive).

I have just been handed a computer from my next door neighbour, it seems to be a home build (or a computer shop build) so im unsure of the exact specs as it is not booting, they are telling me that until yesterday it was working fine... but now it will not start..

All I can tell from opening it up is that it is XP, has an Eagle power supply, a winfast motherboard and 512mb of Dan electric Ram..

when you switch the system on all the fans start and the hard drive spins up, but then there is one beep and the green power led on the front of the case goes from constant green to flashing green and nothing else happens..

I have removed and checked the HD wich is fine, I have reseated the RAM and even changed it from DIMM 1 to DIMM 2, but none of this makes any difference..

Could it be a power supply fault or a Motherboard fault?? or even a graphics card fault?? how can I find out which it is??

I have asked my neighbours if they still have the user manuals but they claim they threw them out when they moved in about 3 years ago...

Can anyone help??

Many Thanks

Welcome to the Lenovo Community !
Sorry to hear of your problem.  What model do you have ?
Try clearing the CMOS to see if that will resolve the start up problem.  Just do this....
1. Unplug the charger / adapter. 2. Remove the battery. (If your model has a removable battery, not an internal one)3. Press and hold the Power Button for 15 seconds. 4. Re-install the battery, plug in the charger / adapter if needed and power up the system to see if the problem was resolved.

Hi, I have Toshiba Satellite L855-14C and recently the DC IN/Battery indicator started flashing orange / amber. The frequency is constant, about every second. This is the indicator that I mean (outlined in red):

According to manual:
This can happen because:
Remaining battery capacity is low (if no charger connected)There is a problem with power supply / charger

I did some tests on my own and if I remove the battery and use just the charger, then the LED does not flash anymore and has white color. If I unplug the charger and keep just the battery in, then the laptop does not even turn on, or immediately shuts down (if I unplug the charger when laptop is turned on already). Windows battery status reports, that the battery is 99% charged and that it is not charging.

Here are some more details about the battery which I dumped using BatteryInfoViewer:

Hi guys well I just hope someone with some electronics knowledge in repairing notebooks would help me out in here.
I got a sager 5680 lappy, and when I plug the lap on AC power without the battery I turn on the unit and instantly goes off, ( I hear a low sparky noise like some sort of short circuit, when this happens the psu light dimms from rock solid ) .
Now if you leave the unit with the battery charging you may be lucky and the battery will charge and the only way the unit works is with the battery on it's bay, as soon as you remove the battery boom unit shuts off.

The Unit does work but only when you plug in a battery and when it charges if you leave it dunno a couple of nights never gets solid green

What I did :

- Could the PSU be bad not throwing enough amps ? even if it shows voltage
on digital meter

- This lap has a separate voltage daughtercard for the battery I removed it when diagnosing this card goes
plugged onto the mainboard and here the battery gets plugged.

- Measured PSU voltage it's working fine 20volts DC

- Checked SMD fuse on motherboard , fine

- Dissasembled the entire unit ripped everything off that might me faulty

- I've read the AC plug sometimes get's broken and I retouched the solder points, once I did this, by miracle the unit started without the battery plugged on. But guess what after I assembled the unit then again , when on AC power alone turned on , and then went off . So I don�... Read more

A:laptop not starting on AC , power light on , I press on button & goes off instantly

The power adapters and the power sockets have an extremely high failure rate in the Sager 5680 laptop. We have seen eight of them in our shop with identical symptoms. While still under warranty, Sager replaced those without a question.

The problem appears to be where the power meets the motherboard. New parts would need to be re-soldered into the system... expensive because it is very time consuming.

Sorry I don't have a solution for you. Working units are available on eBay, if you want to trace the problem between a working model and a failed one.

My Satallite R830 won't turn on.

The power symbol flashes orange 8 times then pauses and restarts. there are 6 quick flashes followed by a longer one on the 7th flash then another quick one. The wireless symbol is lit up (orange) all the time.

If I unplug the laptop and take out the battery and hold the restart button for 30s then without the battery plug in the charger the flashing stops and the power symbol goes green, until I try turning it on, it has a split second where it sounds like it's booting up then stops and the orange flashing resumes.

Same thing happens if I unplug the ac adaptor and the battery and then tried the above but with the battery and no ac charger.

I have tried with another adaptor (same amp and volt output).

Can anyone help?

Many thanks

A:Satellite R830 won't power up - flashing power indicator

>6 quick flashes followed by a longer one on the 7th flash then another quick one

If the power supply microcontroller detected an error the DC IN lamp sends a blinking code.
The short means 0 and long means 1.
I your case this means: 0000 0010

Since error code starts with LSB (least significant bit) you have to read it from behind
0000 0010 -> 0100 0000 -> 40 H (hex)
Now you will need to know what 40 H means

According to some details which I found in internet, the 40H could be the S3V output fault. (S3V voltage is over 3.47V)

However, such errors are mostly related to motherboard problem (internal circuit problem) and from my point of few only part replacement would fix this error.

Last night as I was using it, the screen suddenly went blank and I can't find any way to get it working again.
There's one clue though. When I press the power button, the light under the trackpad (which is, I think, the battery indicator light) starts flashing. It flashes amber twice and then white once. It repeats this a few times before stopping.
I assume this flash pattern is trying to tell me something, but I can't find any documentation for this. So can someone please help me out with a couple of things.
1/ A pointer to the documentation for these flash patterns.
2/ A suggest for a solution for my current problem.

On my NB10t-A-101 the old battery from 2014 got tired and I bought a replacement unit. But with this new battery (and the mains adaptor plugged in) only the left light indicator is flashing red in approx. 5 second intervals, no further action is possible.

When I take the battery out, the machine will boot up happily with only the 19V mains supply. When I then plug in the battery into the live system, the left red light starts flashing ever 5 seconds, the machine will run but not start charging. After shut-down with the new battery in, it will also not boot up again.

My questions: is the battery faulty (brand new, manufactured 2018) or could it be that the system is faulty in the computer itself which activates the battery charging process?

Is there a way to test the battery to see it's ok?

Many thanks in advance for every helpful advice!

So I might have an issue with my Y50 laptop, and I'm not sure what's going on.
Recently I've noticed that I periodically will have flashing lights when I'm on my computer. The power button and power light will blink a white colour, while the battery light will blink an orange colour. These do this at full battery, half, AC power or not, etc. The laptop also runs and works perfectly fine, it just flashes randomly while I'm doing work. I know the indicator lights and show a few things, but they don't seem to match the issue I'm having. Any help would be greatly appreciated.

Have tried all combinations of with battery and mains combinations but nothing changes.

A:Qosmio G20-139 wont power up Flashing DC indicator only

Hmm... sounds like a hardware problem on the mobo...
Check the memory modules.
Remove one and try to power up the unit using one module only.
You should check both with different combinations means you should check also the both memory slots.

My notebook didn?t boot up due to faulty module.
However, if this does not help you, then you will need to get in contact with an local service technician because the guy could localize the faulty part.
But i think it could be a motherboard problem which means that new board would be needed and this can be very costly.

When powered on charging light flashes yellow.
Battery does not charge and if battery removed the laptop shuts down.

At time this problem does not happen.

Moreover, when power cord is removed, battery charges for few moments and then yellow flashing light comes on and charging stops. When shutdown, the battery charges normal and 100% charged battery gives almost 4 hours time.

Can any one please guide about the problem. Is the problem in power adapter? or the battery? or the motherboard/hardware?

A:Satellite Pro L500: indicator flashing amber - battery doesn't charge

It seems that you already posted an thread about similar issue with your notebook some years ago.

In first case it seems that your battery was the troublemaker.

You are talking about charging indicator. I?m not quite sure what LED should it be.
There are 5 LEDs - from left: DC IN / Power / Battery / HDD, ODD / Bridge Media Slot

The first DC IN indicator glows green when power is being correctly supplied form the AC adaptor. However, if the output voltage from AC adaptor is abnormal or if the computers power supply malfunctions, this LED will go out.

The second from left Power indicator glows green when the notebook is turned on. If you turn the notebook into the sleep mode, this indicator flashes amber.

The third battery indicator show the conditions of the batter charge. Green indicates the battery is fully charged, amber indicates the battery is charging and flashing amber indicates a low battery condition.

Are you able to power up the unit without the battery but using just a connected AC adaptor?
Usually this should be possible even if the battery isn?t inserted.

Hi, my X240 laptop has suddenly stopped turning on. When I press the power button, the indicator light flashes green three times. I've switched out the AC adapter, same result. Can anyone tell me what the three flashes indicate? Is my motherboard fried or is it potentially something else I can troubleshoot? Thanks!

this is my first Lenovo computer, I bougth it form a friend that was not using the laptop because he lost the charging cord and was lazy to buy a new one, I bought the laptop for 300 bucks, and managed to find an used cord for 20 bucks, the battery was dead when i pluged it in, but it did turn on when I pressed the power button and the battery charging indicator light was blinking, just as normal, the problem arrived when I discharged it enough that windows asked me to plug in the cord, when I did nothing happend (the computer did not recognize the cord on the task bar and the battery light was not blinking), I was worried thinking that the cord was not good (since it is the 90w version), but to my surprise, the battery porcentage was rising up, but the time remaining was not rising, but when it reached 100%, the time refreshed and all is normal now. the only thing is that when I disconnect the cord it jumps form 100% to 95% instantly.. What should I replace?
