Question about Acer Aspire 1800 Notebook

1 Answer

DC socket is loose

I have a intermitant power connection.
removed battery to confirm problem was the laptop and it switches off
two charger do the same thing
Center pin of laptop DC connector moves slightly

Can you tell me where i can get information to take the unit apart. (Free) I have not been able to locate the assemble information and the one the I purchased is nothing more than a parts list to buy items.
There are two screws located in the middle of the unit that are recessed and refuse to move.
There are four screws under the Display edge. It appears that the screen must be removed to access them.

3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.

Battery Icon reads. Plugged in but not charging. What's the fix?


Confirm that the charger is plugged into the electrical wall socket and the light on the charging unit is on. Ensura all connections are secure and not loose.
  1. If all is in order and the laptop is still not charging, the battery OR the charger may be defective.
  2. Shut off the computer.
  3. Remove the battery for 10 seconds
  4. Reinstall it.
  5. Try charging it with the charger again. If that works, good. If not, call customer support.

Adapter from power cord gets power, but is not charging samsung rv511 laptop


Step 1:
b> If your laptop charger seems broken, it's most likely because the battery will not charge. You plug in the cord, the lights come on, but the charging light doesn't change or blinks repeatedly. When you remove the power cord, the laptop shuts off instantly due to the depleted battery. There's more than one cause for this, and it's not always a broken charger.

Check the connection between the charger and the laptop. It should fit firmly in the DC jack without wiggling. If it is loose, use electrical tape to hold it in place so the charger can receive power. This is a temporary fix, however, because a faulty connection can create sparks and cause a fire or injury. A loose connection will just get worse over time, so have it sent to a DC jack specialist as soon as possible. Turn off the laptop and flip it upside down. Locate the latch that secures the battery and slide open. The battery should pop out; give it a tug if it doesn't. Apply a small amount of rubbing alcohol (Methylated Spirits)to the tip of a cotton swab and use it to clean the battery's connectors. Dirt can build up and interfere with the connection, giving the appearance of a broken charger. Let the alcohol dry completely and re-insert the battery. Slide the latch to secure it and plug in the power cord to test it. See if the laptop powers on with the charger only and battery removed. If it does, the battery is the likely culprit and should be replaced. If the charger is truly broken, the only thing to do is to replace it or the power cord attached to it. Look on the bottom and write down the part number. Call the laptop manufacturer for a replacement charger or search for the part number on eBay. If you purchase from anyone other than the original manufacturer, ask for genuine parts to reduce the possibility of problems. Troubleshoot Mag Safe adaptors

Lose charging port


When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first. http://www.fixya.com/support/r4799950-laptop_battery_power_supply_problems

My laptop powers up for just a few seconds and then powers off before anything comes up on the display screen. This happens even when its plugged into an outlet.


You don't mention if you get any lights on the laptop as it tries to boot up..
Firstly, remove battery, unplug from mains and hold power button down for 30 seconds.
Reconnect to mains and try to boot, if it works ok, replace battery and try again.

If no luck, test the dc voltage at the charger pin, it should be 19 volts ( connect one probe of a multimeter to the inner connection (red probe) and the other ( black probe) to the outer part of the jack.

If this is not outputting 19 volts, try using another charger

Is the DC jack socket loose? If so this will cause it to shut down and the jack socket will need replacing

Check also that the power button is not sticking and (if fitted) the small rubber pin usually near the screen base on the top cover is not sticking in
Remove ram modules, replace one and test it, then the other one to eliminate ram problems

After that, there is a problem with the motherboard

Gateway kav60 not charging. i have to wiggle the cord and sometimes it refuses to charge.


I guess you've got a broken laptop power dc jack or power cable.


Symptoms of a broken Laptop DC power jack:


- The laptop only operates when you hold the DC power plug in a certain direction (DC jack is broken or loose).
- The laptop only runs on battery power (no power is getting through the DC jack).
- The laptop gets no power at all.
- The laptop will not charge the battery.
- The laptop switches from AC power to battery power intermittently due to a loose or broken power jack.
- The laptop suddenly shuts off.
- The DC jack may feel loose.
- Sparks come out of the back of the laptop when you insert the power plug into the DC jack.

I have a latitude d620 i purchased used a couple of years ago. recently, my battery charger light has not been lighting unless i giggle the battery charger body. this has worked and the battery icon on...


1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

Hi everyone it seems to me that the DC connector is loose inside your laptops,try wiggling it about gently at the charger to laptop cord nearer to the dc socket to verify this.Only solution is resolder or new dc socket.
