Question about Dell Inspiron 6400 Notebook

8 Answers

Flashing icon at the top right of my Dell Inspiron 6400

I have a flashing red and green light next to the power light at the top right hand where the screen is joined to the body. The one that is flashing is the battery icon with danger sign inside it. It flashes when it is plugged in and when it is running on battery. When I switch it off and it is still plugged in it continues to flash. However, if I take the adapter out of the computer it stops flashing. What is it and how can I resolve it? Thanks in advance! Aileen

    I have the same identical problem. The battery light flashes red 4 consecutive times then turns green, then repeats. I swapped out with the spare battery and the light glows green as normal. I put the first battery back in and the red fashing light reappears. I will try letting this battery completely discharge and see what happens after that. This is the 83Wh battery and the spare is the 53Wh. The battery does not appear to be overheating, it's actually barely warm, and it appears to be holding a charge well. Incidentally, I haven't used the spare in over 3 months and it still had an 86% charge. Both batteries are manufactured in Japan by Sanyo.

    I had the similar problem. It is 24 months that i got the laptop. Suddenly one day the batter indicator started blinking into red for 4 times and next with green. The batter was charging. Even though we remove the power cable from the laptop, and laptop is running on Battery and still the same blinking with red continues. When we connect the power cable it is the same blinking red and green. never stable to green at all.

    What does that mean? can't i use laptop with power connected?

    my dell inspiron 6400 is barely 18 months old and i am seeing exactly the same problem of bllinking orange and green light which stops after i remove the battery and work only on ac adaptor but otherwise the blinking continues. Is that all the life of the DELL battery? what is the solution ? Is it a problem if I continue using the same battery till it drains out. Can it possibly cause damage to my laptop

  • paulfp May 07, 2008

    Yep, I have the same problem too. I've had my Inspiron 6400 for less than 2 years.... about 21 months I'd say. About a month ago it started doing this and continued for about a weekish, in which time I emailed Dell who said to buy another battery (they're almost £200!!!) - then it stopped, but yesterday started doing it again.



    This seems to indicate an actual fault, not just the battery losing its ability to hold charge which I would expect as normal. But if this is an actual fault then I think it's unacceptable that within 2 years of spending £700, I have to spend another £200. Products must be warrantied for a "reasonable" amount of time, so I will be emailing them again to protest!

    I have an Iinspiron 8300 with the flashing orange battery light problem. I think I found a solution. Unplug the power cord and boot the computer. Go into the bios settings and access the battery life and power settings. You can't make any changes, but merely going into these settings seems to re-sync the battery with the computer and solves the problem. Shut the computer down and replug the power and no more flashing orange light. Note that if you go into the bios settings with the power cord plugged in, the batter is not recognized and this routine does not work.



    Good Luck.

    I have a Dell Inspiron 6400 with the green/orange flashing icon issue. I'm not sure if this will help anyone or not, but mine appeared to come on after I unplugged the adapter twice while looking for the cord of a usb drive I had attached to it. The second time I plugged the cord of the adapter back in it seemed to snap a bit, like it was charging the capacitors in the supply. I am wondering if this fault can also indicate a voltage spike, or brownout. I was also thinking that maybe when I unplugged it the batteries were not up to the task of running the laptop. I don't think that this is the case though as the laptop runs for 2 to 2.5 hours on the battery. Mine has been flashing for about a week now and has not shut off. My laptop is about two years old.

    I too hav the same problem, I hav replaced the battery but the problem not sloved.

    It is the problem in Motherboard not charging all cells in the battery


  • blue_cat Dec 11, 2008

    I have the same problem, flashing orange light of doom. This is the 2nd time this has happened. The first time Dell replaced the battery not a problem and it was out of warranty. This time they simply said that the battery is out of warranty so no help for me.

    My big problem is that now the battery won't charge at all, its at 0% and Charging, but not actually charging. About a week ago I could take it of the main power and use it for maybe 10 mins. This week if I take the main power out the laptop shuts down. This is so frustrating! I tried to flash the bios but I need at least 10% battery to do that.

    Any suggestions on what I can do? (aside from buying a new battery)


  • jpndpeace Mar 12, 2009

    ok so i have a inspiron 1501, and it is a LITTLE over a year old (well i bought it new last year around this time) and all of a sudden when i start up my computer it says that the AC Adapter was not recognized. SO my cord always gets knocked out, so i didnt realize that my computer wasnt ever charging, so now my computer is at 0% battery, plugged in, NOT charging. but my computer still works plugged in. nothing was showing up on my battery icon for about a week after this happend, and NOW all of a sudden, its doing the 4-orange 1-green blink. i dont know what i should do :(

  • ohshi Mar 27, 2009

    I am having the same problem. I bought this Dell 6400 maybe three years ago and maybe two months ago the battery just stopped charging. However, right now that's alright as I mostly use it in my room and have it plugged in all the time. But that it's started flashing red while plugged in is worrying. I don't know much about this sort of thing, but if the battery itself dies can the laptop still be run on AC power? I'm at the end of my semester here so if it dies before that I'm in real trouble.

My Inspiron is 3 years old and I just had the battery life indicator start blinking to suggest it is near the end of it's useful life.

Strangely enough, I still can run it for about 2.5 - 3 hours on battery so I think it's just the bios sending out a false message because it's just outside the 3 years since I've bought it.

I'm just ignoring it until it croaks.

Posted on Apr 05, 2008

I've visited a few forums on this topic, and it appears most dell laptops have this odd issue of the battery "dying". It is generally about 2 weeks out of warranty when this happens, and the people posting on the forum stated they had physically taken the battery apart after the fact and tested it, just to see it work absolutely fine. The running conspiracy theory is that the BIOS that communicates with the battery is rigged. I can't validate any of this yet, all I know is my Dell Inspiron 6400 is now getting the 4-orange 1-green blinking light cycle and I'm trying to fix it.

(I posted this above on the "Blinking Red Light" question.)

The batteries are terrible on the 6400. I hardly ever use it on battery, but my first battery died after only about 12 hours (really) use. The backup battery is failing now. It says it's fully charged when I check, but the power disappears after about five minutes of use.

The Dell forums show this is a common problem but Dell hasn't issued a battery recall or a fix. The batteries aren't covered, even though they are hardly ever used, and as far as I know, there's no way to know how much they've been used.

I agree with this solution in general, but do not think it will absolutely work.  The primary battery on my Inspiron has been having some sort of problem for quite some time; pulling the primary battery and unplugging it (leaving the extended battery installed), will frequentlly let the PC start. At the moment, my primary battery is 89% charged, power state is blank; while the extended is 96%, power state discharging,  yet the red power warning flashes continually in three-flash bursts.  Pulling the primary battery stops the flashing, leading me to suspect that the primary battery has to be repaired or replaced.

Seems your battery cell is the one having that issue. try replacing the battery or plug the laptop and let it recharge the battery to full.,

Dell inspiron 6400 touchpad and keyboard work intermittently. battery light was flashing red this morning. i have to hit the keys several times before they work. laptop is plugged in.


sounds like your main battery needs replacing,move your mouse over the battery icon in the system tray(by the clock),to see if the battery is charging. If it is battery needs replacing. This can cause all kinds of strange issues .

Flashing battery icon


The machine is telling you the battery is not charging or is otherwise no good.

The battery for this unit is subject to a recall, if it has part #OU091 or W1435. This recall started in October 08. Go to:

for more info.

Alternatively, bring your power supply to a Radio Shack, and make sure it is putting out the requisite 19V DC power.

The first thing I would try is to get a new power adaptor. You can find a OEM on ebay probably for about $20. Just type in your model number on the search section on ebays homepage.

Flashing green and orange battery light on body of laptop


The flashing orange light indicates that the battery isn't working properly. This could be due to either the battery being worn out, or a battery fail safe has kicked in. Either way the battery will need to be replaced in order to fix this. Since the performance isn't quite right, I'm going to say that a fail safe has engaged, you can confirm this by running the computer without the battery and see how the performance is. You will need to replace the battery, and the replacement will make the machine work properly.

Flashing red and green battery light dell 6400


Ok, probably not the battery. With Dell machines, once they overheat to a significant level, it locks an overheating code into the bios, so you will have the light codes at start up. I've had three C840 machines with an overheating issue come through my shop. In order to get the machine working again, you will have to fix the problem that caused the overheating, then there is a download at Dell's site to clear the code. If the initial problem isn't fixed the code won't clear. On the machines that I worked on, 1- had a hair wound in the fan and the other 2 had bad fans one burned up the processor. I believe the 6400 and the C840 is basically the same machine. It's been a while since I worked on those machines so I can't remember exactly where the clearing download is at Dell's site, I do remember reading several forums at Dell on the subject. I hope this approach helps a little more than my last. If you have any more questions please ask.

Flashing battery icon


Battery is shot, time for a replacement. Keep in mind that a Dell battery can aquire a dead short, this won't hurt the system, but it can keep the machine from starting up. If you find that your machine won't start up try pulling the battery.
