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.

Where can we buy a battery of acer laptop aspire 4736/4736z/4336 series?How to take care of the battery of the laptop especially acer brand?


You should get it at your local computer store.

The replacement doesn't have to be an Acer. I have seen after market replacements, that work better than the original battery.

When you buy a new battery, you should consider looking at the number of mAh. It is written on the battery. This number indicates the time before complete discharge.

I have seen original Acer batteries that were 2200mAh, while replacements were 4400mAh.
So if the 2200mAh gives you 3 hours of working time before recharging, the 4400 could give you twice as much, so nearly 6 hours.

I have used the new Forza brand replacement batteries on a Acer Aspire One, and I am very glad with the results. I am not sure if they have the model you are looking for. if they have it, you should get one.

Hopefully this helps you

Acer travelmate 4100 works fine with no battery


Try to use another OS, like Ubuntu Live, and see if the mouse and KB will freeze. If they wont freeze, It is better to reinstall the OS.

If they will freeze again with Ubuntu, then I am sorry to tell you that the battery life has finished.

The only thing to do is to replace it for another one new.


Thanks for rating!!

Acer extensa 5620 laptop will not boot uo


Then you can check 2 things to see if the machine will boot. If not, then you'll need to get it repaired. FYI, I repair Acers.

Step 1 - remove the battery and the A/C adapter from the back of the computer for about 2 minutes. Replace the battery and the adapter and try to start the machine. If that doesn't work, go to step 2.

Step 2 - Check that the A/C adapter is getting power and the LED for battery charging on the front of the computer lights. You can check the voltage from the power supply with a volt meter, if you have one -- it should read around 18-19 volts. If either of these steps don't work, you'll need to get it looked at.

Problems could be with the power supply, motherboard, power switch, CPU or something else that only time and expertise could properly track down.

Ive replaced my laptop battery.......it does not recognise...or c


since putting back the old ones charges the battery, then the charger unit is good. its best to replace the old battery pack with the same rating. the charger might be having some difficulty due to a higher rating of the new one.
