Question about Dell Inspiron 710m Notebook

Wont Power up

The AC plug into my laptop was having issues, where I kind of had to hold it in place for it to charge battery/ power up the laptop. I left it on over night I take it had a bad connection battery completely drained, and now when I try to power up nothing happens. I don't see any lights on the laptop at all. I am wondering if the AC adapter connection on the laptop got unsoldered or broken and if the mother board needs a new connector installed. anyone else have had problem with the AC input ??

    I already checked using multiple adapter, I am almost positive the Jack is either broken off or soldering came off. I haven't opened up a laptop before so I am little hesitant. I have worked on plenty of PC's. I am just not sure how delicate inside of laptop of is, I don't mean electrically, but more from handling it right

    Thanks for the helpful comments, I think I am going to take it to a local shop to get the connector replaced just to be safe

DC Jacks are commonly failed on all laptops period. Its a port where the Consumer is applying pressure to the board and a cord is constanltly getting pulled. Dells are a pain at times because the jacks are sensitive and the layout is not in My opinion a good design. IE: Inductors, Caps, Data issues..And Other components cracking from normal use. These are also not a cheap jack by industry standards and weve repaired a ton of them..

Try an adapter first but I am doubtful it will solve as you stated the connection was bad prior..
If you need more help yell..

    If its a familiar Model Dell You will have a 19V Feed .A 3.3V Data. And a Negative..All at the jack and do not short while testing voltages.. You will open a transistor and maybe kill the BIOS chip doing so. (Weve seen these before)... Look to see if its the Round Sony looking adapter cord end... (Its the Easiest way to tell)....If it is contact back prior to checking...

    It can be tedious and this is not a recommended model for an at home experiment. Weve seen too many repairs where the 19V Feed gets shorted to the 3.3V data circuit killing up to 3 components downline including in some cases the BIOS chip. Too much room to fail here is all I'm saying and if you havent done jack replacement on a simpler machine like an older Compq/HP job it out as you can easily create a bigger problem.

    Just some food for thought..

It goes dark, shuts off constantly. Battery meter isn't showing charging.


Unplug the battery and plug in the AC power plug into the laptop;

Does the laptop start up and stay on?

If yes,

Then put the battery in WHILE IT IS ON; See if it starts charging.

If it does not; You have a bad battery and need to replace it.

If it does start charging here's what happend;

Some laptop batteries if they are fully depleted on charge will not let you power up the laptop EVEN IF the power cable is plugged in. In some cases the PC won't turn on at all.

The reason for this is because the battery must have a certain % of charge in order for you to start the PC even IF the power cable is plugged in.

By removing the battery we eliminated the battery as being a cause for this issue; Once the PC is up and running in windows.. LET THE BATTERY CHARGE! You'll want at least 10% charge minimum for the PC to start up.

If however the battery replaced still doesn't hold a charge it's going to be the AC Adapter power cable that's causing the issue.

Best advice start off with the power cable replacement first; This is the cheapest to fix; Otherwise the battery can cost in excess of $50-$150 or more. But universal AC power adapters can be cheap $70 or less which varies depending on laptop.

My laptop battery willnot charge


For this kind of issue, you may try the following troubleshooting steps:
Take your laptop battery out, plug in the charger and see if the laptop works.
If it works, the battery may be the problem.

Check the AC Adapter

Check to make sure the adapter is plugged securely into the wall outlet, connected firmly to the adapter box and to the back of your laptop.

Most AC adapters have a little light in them on that rectangular box in the middle of the cord that lights up when it's getting electricity.

If that light isn't on, try a different outlet.

Check your fuse or circuit breaker box and plug a different device into that outlet to make sure there is power to it.

If it still does not light up, your adapter could need replacing.
Also check the adapter box for signs of warmth, as it will generate heat when it's plugged in. No heat means no power.Remove the Battery Sometimes it's as simple as a seated battery.

Remove the battery entirely and clean out any dust, lint or hair that may be clogging the connectors and preventing a proper connection.

Reseat the battery securely and make sure the little locking pins that hold your battery in place are securely fastened and there is no movement.
hope this helps

Toshiba A205-S5809 Wont power on


Try another cord/charger with the EXACT same power specs. If you have a multimeter, verify DC voltage at the AC jack plug. If the AC jack, in the laptop, has been pulled, damaged, it's may have a loose connection. You didn' say if ANY LED's, battery charge, work? If the battery is charged and it doesn't start on battery only, then you have other issues. It may need a ride to a Qualified Computer Tech.

hello

shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

It just wont turn on i have checked the power lead and its ok its an acer aspire 5050 laptop


Hi. I would suggest you double check the ac adapter if the powercord is properly attach to it ot also you might want to try powerdraining or powercycling your computer. To do this you must turn off your laptop then remove the battery and unplug the ac adapter then press and hold the power button for 20 seconds while the battery and ac adapter is out, after that place back the battery and plugin the ac adapter and try turning on your laptop, if this doesnt work then try power draining it again and just use the ac adapter or just plug it in without the battery then try again turning it on. If it still has the power issue then try a known good ac adapter so that you could double check that it is not an ac adapter issue or a battery issue. If all that trouble shooting step doesnt work then you could also try calling acer tech support to help you on your issue if your machine or laptop is still under warranty they would help you fix it by sending that laptop to there depot without any charge. Hope this Helps

Dell 620 Battery Issues


Chances are pretty good that your battery just needs to be replaced. Over time all rechargeable batteries loose their ability to hold a charge. It's also possible, but less likely, that there could be an issue with your AC power adapter or the charging circuitry inside the laptop.

Best bet would be to find a similar laptop with a battery that does charge and switch. If the problem follows the battery then you need a new one.
