Question about Dell Inspiron E1705 Notebook

4 Answers

Dell laptop (E1705). Battery won't charge. Battery is charged to 7% (therefore I can't flash the bios.) If I unplug the AC Adapter, I get the warning that the battery is low. BUT the laptop remains powered up (therefore the OS "sees" and uses the battery). The Battery icon in the task bar shows the "AC Plug" icon when plugged in. The icon switches to the battery when the adapter is unplugged; BUT THE BATTERY ICON has a red X thru it. When it worked properly, the icon would show a lightning bolt with the plug icon to indicate the battery was charging. It never shows the lightning bolt anymore. The LED's on the battery work. I am tempted to put a volt meter on the battery terminals until I find voltage, then trickle charge the battery with a DC power supply (I work in electronics and have variable power supplies at work). I also have had trouble with the OS NOT seeing the AC adapter from time to time. I've seen a pre OS start up warning that says "does not recognize AC Adapter" but not lately. Is the utility that manages the AC-battery-charging circuit corrupt? Can these drivers be disabled-removed-reinstalled? Do I use the device manager for this? Do I simply need to throw the battery at the dog that is taking a **** on my lawn, and get a new battery? The battery is 3 years old. RED X on battery icon makes me think I need a new battery, and the occasional ?does not recognizing AC Adapter? error makes me think I need a new adapter. If I need new both, I?ll get a new laptop 1st. It ain?t worth the cost of both. Please help. And Thank You!

    hey thanx. I kinda figured the battery is bad. I still want to reload the utility or software that manages power. I'm trying to figure that out now. thanx for the quick response.

    I bought a brand new DELL battery. The real deal. It has 31% charge. My laptop won't charge it either.

    So strange. The AC power icon shows or the battery icon shows in the task bar. BUT IT WONT SHOW THE CHARGING ICON. I flashed my BOIS, now that i have a battery with more that 10% charge. charging. Do I need to buy a battery charger?

    NOTE: the battery icon does not have a red X thru it, so I guess it is really a good battery.

    Do Dell laptops simply loose the capacity to charge a battery after they are a few years old?

    I've had this problem several times... I bought a new battery and it was NOT the battery that was the problem. The problem was the adapter cord... I've gone through so many cords and I've found that after awhile the adapters give out enough energy to keep the laptop running on 'ac' power but not enough to actually charge the battery... weird, I know.

    Try getting a new cord, they are a lot cheaper then a new battery.

    I really appreciate the input...really. But, It's not the battery. I have a brand new OEM Dell 6 cell battery. The laptop will not charge the brand new battery.

    I'm going to break down and try rtrahan's solution. I wanted to avoid buying more useless products because I think it is the utility that manages power for the Opreating System. (WindowsXP) I simply do not know how to get to that utility.

    I may delete the utility in the device manager and let the OS reload it. I tried flashing the BIOS, hoping ACPI would fix itself to no avail. I may try setting the BIOS to it's default setting...I don't know. Oh well...Keep the idea's coming...please. And rtrahan, I will rate your solution after I borrow an AC Adapter...I'm too cheap to buy a new one...especially after paying $80.00 for a new batery.

    Edit last comment...It was the "Guest" Solution to get a new AC Adapter. I tried rtrahan's solution of a new battery. I think trahan was correct as the battery icon no longer has a red "X" thru it. But the laptop will not charge the new battery. L8r

    The problem is FIXED! FYI it's the BIOS...not the OS, that checks the adapter.

    Dell had trouble with AC Adapters burning up but it was caused mostly by people using inappropriate adapters for their laptop.

    SO...Dell has a hardware solution of a chip in the adapter and the BIOS looks at this chip. If it doesn't like what it sees, it will let you power your laptop with AC, but you can NOT charge the battery!

    When you flash the BIOS, be certain you have the proper AC Adapter. can boot your laptop and enter the BIOS. Navagate to the AC Adapter, then you can unplug the adapter and plug it in, and watch the BIOS identify your adapter...or not. This is valuable info.

    l8r all and thanx for the help.

    I am trying to flash my bios but the program requires 10% battery life. I've already bought a new battery and determined that isn't the problem. Now I have 2 discharged batteries and can't flash the bios to see if that's the problem. Help!!!!

Try hitting Fn+F2 - that worked for me - it's a BIOS setting that disables battery charging.

Yes you definately need a new battery. Three years is not too bad..but they do wear down after a while and don't hold a charge, no different than a car battery, its gonna go out eventually just don't know when. Once you get the new battery and its charged to 100% you'll be able to stay on the computer for about 3 hours without the adapter. If the adapter is only doing problem sometimes then keep it for now anyway..maybe six months from now it will also need to be replaced..get the battery from your computer manufacturer and make sure its Lithium Ion. That is the lastest, the one you have now is problably Nickel..don't throw it at the dog, it don't know, throw it at the owner of the dog, it's his fault...Good Luck, let me know if you have any questions.
Please rate this solution.

    If you're talking about being able to manage the power like sleep, hibernation etc, then the BIOS update is to include ACPI, or Advanced Configuration and Power Interface. Good Luck..if you have any questions about that just repost we'll take care of it.

    ok you ready for my battery lecture :)..Sometimes batteries have a problem with battery memory..battery memory is a condition that occurs with some types of batteries where the battery becomes internally conditioned to run for less time that designed capacity. For example, if you routinely operate the computer using the battery for an hour and then plug it back in to an AC source, the battery can become conditioned to run for only that amount of time. To correct it, fully discharge the battery and then recharge it for at least 12 hours. Repeat the process several times and it will slowly change it operating times. Some batteries just get old and die. Nickel metal-hydride (NiMH) have a life of about 600 charges. While Lithium batteries last for about 1,200 charges. Nothing can be done to extend the life it just needs to be replaced. The type of battery is displayed on the battery. Hope this helps.

    that's some good info to know..I never would of thunk it..Seems like Dell should put something on there support section of their website. That would save a lot of people a lot of money, but then again I get they are making a killing on new batteries :)...

Dell m5110 laptop won't charge new battery and ac adapter is not recognized in bios

Try another AC cord/charger with the EXACT same specs as original. Is the battery a genuine Dell battery, if not return it? Some aftermarket laptop batteries don't play well with your computer, the pin-out connections aren't correct and MAY be a fire hazard.

I have a Dell Inspirion 1525. I have a fairly new after market replacement battery which I have only had now for 4 months. I am using Vista. As soon as I unplug, computer shuts down. I go to power settings...

The adapter is working correctly. The battery is either slow to charge or in need of replacement.

It's possible your battery isn't charging at all so to test this boot into bios -> battery status and watch it run overnight.

I have no led light on my e1705 when i press it and nothing comes on

Things to check:
1. AC adapter cord, esp close to the brick. Does the green light come on the brick? If not, replace the adapter.
2. Reseat battery. Check the battery charge by depressing the battery indicator button on the battery. Does it have a good charge? If so, then it could be the connection to the mother board causing the issue. If not, then replace the battery.
3. If both the battery is good and the AC adapter is good then you are looking at a mother board issue.

Dell E1705 will not charge aftermarket battery. Is there any work around. AC adapter is ok.

Hi there!

Try to check a few things first.

Go to the BIOS set up, which you can access by pressing f2 when you start up the computer,
Then go to the option that says battery info,
Check if the ac adapter is detected,
And check if the battery is detected,

If any of this things is not detected
Then try this things,
If in the ac adapter it says unknown,
boot to your windows normally
then make sure you still have at least
12% on the battery charge.
Then download the latest flash BIOS
update your BIOS then after you update it,
it should fix your not charging issue and fix the unknown ac adapter if ever that's the case,
But after you do that and the same thing happens,
You'll need to replace the motherboard of that computer.

Hope this helps!

Dell Inspiron e1705 no longer recognizes AC Adapter and battery won't charge. Tried updating BIOS, but exe file won't open becuase the Flash app won't run. What can I do?

If the system doesn't recognize a the AC adapter, a BIOS flash will not run as system needs to ID the battery any AC to run the flash.

  1. Try a different AC adapter if one is available. The system IDs the adapter by the pin in the center of the DC connection to the system. If the pin is bent or missing, then the system cannot ID the AC adapter and the Battery Charger is disabled.
  2. If issue occurs with a new or known good DELL Branded AC adapter (Any Dell D Series adapter should work on system) then the motherboard is bad.
AC adapters run about $25

Motherboards around $150

I am having the same problem

The bios can only be flashed if you have more than 10% battery charge. check if you have any other AC adapter. is the battery does not charge with another adapter then it could be a battery or motherboard fault. Try another good known battery, If even a good known battery fails to charge then its a motherboard issue. Call technical support and get the motherboard replaced.

My battery won't charge in my Dell E1705

The current bios version is A09. The bios version on your system can be found under the Dell splash screen when you first turn on your computer or by going into the bios itself. If your version is older (A08, A07, etc), you can go to and at the bottom click Drivers and Downloads. Get the 7-digit alphanumeric Service Tag form the bottom of the laptop and enter it when prompted. It will take you to the Download page specific to your computer where you can then download the current bios.

While some battery issues have been taken care of with a bios update, in my experience the issue is usually the battery itself not being able to hold the charge. On average batteries develop problems about a year to 2 years after purchasing the laptop, just in time for the warranty to run out. This means a new battery will need to be purchased. I have also run into the power adapter not charging the batter properly due to the the adapter failing or a break in the cord coming from the wall outlet or from the brick to the laptop. Verify that the power adapter is working properly.

Dell Inspiron 9400 will not charge - AC adaptor not recognised

Does the laptop power up just no charge the battery? If the laptop does not power on then you may have a bad power supply in the unit. If it does power up than you most likely have a bad battery connector of blown fuse on the motherboard. The flashing of the BIOS is done with a bootable cd or floppy but this will not keep the new battery from charging. The reason Dell states that you need at least 10% battery to flash a BIOS is because if your AC power goes out while you are doing a BIOS upgrade and you don't have battery power the BIOS will be incomplete and your laptop will not boot again without replacing the motherboard.
