Schematic for acer travelmate 4672 battery

Battery voltage for laptop is to low to charge. I'm not sure what each of the seven leads do. I was hoping to boost it with a power supply. I'm not sure how to check the battery.

Hi I have a problem with my acer travelmate 5730. My laptop is always in plugged coz i use it,but lately when i move the laptop the sound of the dc connection is bipping all the time and i have to play...


Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

Wont Charge, Message critical battery voltage. when I try to switch on Travelmate 4670


First of all, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

I have a travelmate 4060 laptop and I just replaced the battery through best buy with a generic one that was compatible. It is always saying 23% full. How do I charge this battery?thank you


1)Reason:
a.The battery has no voltage.
b.There is problem with charger, as it has no output electric current.
c.Low charging efficiency due to external cause.
2)Solutions:
a.Test whether the charger has voltage and output electric current or not.
b.Check if the charger is well contacted with battery.
c.Activate the battery with voltage and current 1.5 time higher then the highest ones of battery. (Use this method only when the battery can't be charged.)

My Travelmate 290 series is not working...


Try taking the memory out and then put it back in making sure it seated correctly then start using AC power lead it's probably caused by letting the battery get too low before recharging.Use a start up disc to get it going if you have to. Good luck

New 6600 mAh battery won't charge


Is the AC adapter the original that came with the laptop or is it a replacement?
Check the label on the laptop (on the bottom of the laptop) for the voltage and current requirements.
Check voltage output of the adapter with a multimeter, this voltage should be slightly higher that the voltage than what is shown on the adapter's label because there is no load on the adapter.
It could be that the current (amps) that the adapter is delivering less power than the laptop's requirements, whilst it can power the laptop it may not be sufficient to charge the battery fully.
Try charging the battery overnight by shutting down the laptop but leaving it connected to the mains. Then boot up the laptop in the morning and check the battery's charge state. If the battery is at or near full capacity, then the problem is a (part) faulty adapter.

Battery problem


I'm fairly sure that means it is trickle charging as my laptop does. Don't worry too much about it. It actually helps the battery have a longer life span. Another thing it may be however is that there could be an issue with the AC adapter possibly not giving off enough voltage but still enough to keep everything going. (so within 0.05volts)
