Question about Dell Inspiron E1705 Notebook

Laptop does not work with AC adaptor, does not charge. Mother board issue

When I tried to fix my AC adaptor, I think I connected the two wire in opposite way and damaged the mother board. Now the laptop works with a charged battery. Deos not work with AC adaptor. Battery does not charge.

Sent it to Dell. Dell said the mother board needs to be repalced and they charges $500. Did not ask them to fix since with $500 I can buy another new laptop.

Since the laptop works with a battery, I'm thinking connecting a AC adaptor directly to the battery connector (connector on the laptop which connects to the battery) or Or open the battery box, replace the battery cells with a
AC adaptor (At least it can be used as a desktop).

I saw an article about how to open the box and replace battery cells.

I just wondering if there are other better solutions?

Thank you.

    Thank you for your response. The battery is 11.1 volt, the original AC adaptor is 19 volt. What I'm planning is to get a 12v adaptor and connect it to the battery box and remove the cells.

You may be able to get a battery charger but its rare.

If you do wish to use the AC adapter, take care with positive and negative. Also the voltage of the battery is actually lower than the AC adapter in order to get charged. I don't know what is going to happen if you do choose to use AC adapter as battery. 75% chance that it will work.

Good luck!

    That should be OK.
    When you buy the AC power adapter, you should also consider the the Current (Amps). You would want something between 1-2 Amps.

Power on problem



hello my friend,
Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.

1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.

hope it will help you today.

My acer 5920 wont charge or wont work on ac adaptor but the ac adaptor works fine on my friends laptop


Either the AC port on the back of your laptop has a lose connection - if operation without battery is an issue, or if battery charge only is issue - then battery may have to be reseated or it is at end of life. Test by removing battery and running AC alone. if connection port is bad, laptop will power off immediately/unexpectedly. Good luck! btw - batteries for this unit are around $40 on ebay

DELL 1525 laptop boot issue. When switching ON it shows only blank screen. Grateful if you could help resolve this issue


Have you got an external screen you can plug in to prove the video? Try this check list:

Dead Laptop.

Try firstly removing the laptop's battery as it may be at a critical voltage and the system will not start because of it. Plug in your ac adaptor and monitor what happens. Does the power light illuminate? If it does it should then boot up, if it doesn't, try a known good ac adaptor before going any further.
If the adaptor is fine then you have a mother board fault and should contact a dealer/repairer for further advice.
Hope this helps.

My Acer Aspire 9805 battery was replaced. For


It could be an AC adaptor issue.

It should boot when connected directly to the power outlet through the laptop adaptor. If it is not boot, then the adaptor might not be supplying the needed power to boot it up.

If it is possible, try to isolate the issue. Charge your new battery using another laptop. Then plug it in your laptop to see if it works. If it will work, then it is the AC adaptor of your laptop that is defective. If the charged battery still won't make the laptop boot, then there is something wrong with your laptop hardware. If could be a motherboard issue of your laptop.

Our Laptop just keeps going off. Replaced the AC Adaptor, and still having the came problem.


Need more info, but if it powers and shows it is charging, then it is probably a heat issue. I would try taking a can of compressed air to the fans and air slots. try to get any dust out.

Otherwise, if it is not charging properly it may be the dc input, meaning either a dc input cable (about 20$) or a new mother board (a few hundred);

Laptop not charging


Double check and make sure that the AC power cord is ok and that it's firmly connected to the laptop. Also check and make sure the cord or part that goes into the AC adapter converter is plugged all the way in. Finally, most laptops will have some sort of a "Plugged in" indicator or LED light on the laptop indicating that it's plugged into 120V AC. If you seen nothing like this, then it is most likely the power cord. If your battery is bad or was going bad, the laptop should still work when plugged in. Finally, make sure that your battery is firmly seated into the laptop. Some laptops will not function when there is no battery, even when plugged in. If you determine that either the battery or plug is defective, of course, you can order a replacement online or from the manufacturer. You can also try EBAY for better prices.

Good luck!

A.c.adapter and mother board


its a problem with the dc jack in the laptop, thats where the charger plugs into.

The solder joints are loose to the jack and need to be resoldered. It will tighten the connection of the jack to the motherboard so that way you can plug in the ac adaptor and not have to hold it in.

An electronics shop can do this or if you have some soldering experience you can do it.

Compaq evo n610c battery not charging


Hello All;
I used to have these same problems. I replace my BIOS battery, which I know was dead, because all settings get reset when I unplug the power and remove main battery. You might not have to replace it if its still good. Back to the main battery problem, You have a good change of solving this by going into BIOS, and under Tools there is a Battery Calibration option. Do the calibration for the main battery and-or other optional batteries attach and it will most likely solve the problems. This calibration process will take a long time; 1-charge, 2-discharge, 3-recharge, so leave it over night or however.

There was a mention of updating BIOS. This could solve the problem too, because BIOS controls the charging unit. Also, make sure you have Compaq Power Management install on your OS, (download at hp.com).

One note: it will not charge if the battery is about 93% or higher. 93 is not exact, but close to 90%. so test by discharging to below 90% and it will start charging again.

If anyone tries this, leave a post of your success or failure.
