please measure the output for your charger,normally they have 19.5 vdc exactly, if they do not measure the adapter is faulty, repair or replace.If the output is o.k the battery can be faulty. Use the software diagnostic coming with the computer, restart the computer HOLD the key f2 or esc depending of your computer model, and make the diagnostic.try again and see what is the result, if the battery is o.k or faulty.God bless you
You need to get the DC Power Jack Either Repaired or replaced...this is the "female" port where your AC Power cord plugs into.. To Repair the current DC Jack...First you'll need to look closely at the Positive posts to see that they are not broken.. If visibally ok.. then you can look at the Solder Connections.. they will need to first be Desoldered.. Cleaned, then Resoldered back in place.
I fix these laptops as a side business and sell refurbished ones on ebay...I've seen the problem you describe but I'd need to know more about how fast they are blinking, etc. When all the lights flash about 2-3 times per second, I've found it to be a motherboard issue normally caused by a faulty power jack. That can be fixed but it means disassembling the complete laptop down to the motherboard and either re-soldering or replacing the jack. If you have access to a charged battery, disconnect the AC adapter and try to get it to boot cleanly from the battery. This will tell you if the problem is at the jack or someplace else. Post your results and we'll go from here.
Hi, if the Notebook is still under Warranty it is not recommended to remove and solder the Notebook with a Female DC Input socket of the Notebook. Although the DC input socket is available in any near by Electronic repair shop, please repair only if the Notebook Warranty is expired.
It might be an issue with the adapter, the battery or the AC jack on the motherboard. First up see if your AC adapter's power LED comes on when plugged into a power source. If it does, then check if the Lights at the front of the laptop indicate that the adpater is plugged in. If they light up then it means that the laptop's battery is faulty and needs to be replaced. If the lights dont light up then it means that the AC adapter jack on the laptop has bad solder joints and/or damaged. It is located at the underside of the motherboard where the AC adapter is plugged in. You will need to take the laptop apart and re-solder/replace the jack.
You can find the broken piece on line to purchase,This can be repalced by soldering it to the motherboard.You will need to find someone to replace this probably a tv repair technician who is good at soldering small circiut boards.You can also purchase the motherboard and replace it
I had problems getting an Acer Extensa 4420 to boot or to enter bios. It would never complete the post. After taking it apart, changing the CMOS battery and making several other adjustments I read that a faulty DVD would cause the problem. I removed the DVD and it went right into Windows VISTA. So I put the DVD back in and had the same problems over again. The issue is a faulty DVD and has nothing to do with the motherboard, or the CMOS battery, or any of those other complex issues. It is simply a faulty DVD that refused to allow POST to proceed.
You are correct about the DC plug on the 1100, they are well known for the problem you posted. It could be one of two things, the solder points where the DC jack is soldered to the motherboard could have "cold solder joints" and re flowing the solder will fix it. Or the DC jack itself is faulty (the more common issue with these Inspirons) in which case almost all PC service shops will insist that the Mother Board has to be replaced (Not worth replacing), but you can obtain the jack for a reasonable fee and either replace it yourself (if you are very good at desodering and soldering, It's surface mounted, and not through hole which through hole is a lot easier to do), or open the laptop remove the Mother Board and take it in to a reputable electronics shop and have them use their state of the art equipment to replace the faulty jack for a reasonable fee. Good luck.
