Hi Tminlun,

Please see if the battery is under warranty and get it replaced from Lenovo. I faced the similar problem last week and got the battery replaced and now it works fine.

I have a older toshiba laptop and i think it has a bad battery will this cause poor performance even when plugged in to ac power


The purpose of the battery is to have a backup when there is a power failure. Try unplug the battery and just use only your AC power adapter. If it is working then don't use your battery anymore. It will not affect with the performance of your computer. Good Day.

Hi there, I have just moved house and when I went to plug my HP 510 desktop back in there was no power. When I plug the main cord in the back the green LED flashes on and straight off again. Can anyone...


Are you sure that particular socket has power or is controlled by a wall switch? Sounds silly but I have had quite a few like that with a desktop. Take the battery out of the laptop, remove the AC adapter and push the power button in for 30 seconds to bleed off any residual power. Now plug in the AC adapter only and try to reboot.

I HAVE A LAPTOP ACER AND THE POWER DOES NOT TURN ON


It could be a battery problem. Try switching to AC mode by plugging in to an AC outlet using your Acer power chord (battery charger also). If the charger led don't light, it means it's defective and it can't charge your battery. Please try another power chord or battery charger then. Just remember to take out your battery when using your laptop in AC mode to lengthen your battery life. Regards!

Acer laptop shut of during power outage .


From the Acer website:

Issue
Power Issues or Will not Boot
Solution
If the notebook does not power on:

Make sure the ac adapter is correctly plugged into the notebook and into the power cord.

If everything is plugged in correctly and it still will not power on, follow these steps to complete a ‘power reset' of the notebook.
  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
Also, depending on whether your power went down "clean" (quick and stayed off), or went down and quickly came back on and off many times. Or when it came back on "clean" (came back on quick and stayed on), or it came on then off many times, your power supply may have been damaged from the power surges Are you having any problems with any other appliances?

Might be stuck in hibernation. Pull the battery and ac power for about 1 hour. Replace and try to boot. If fails, pull the battery and try to boot just off ac power.

This isn't a software issue. If your laptop is still under warranty have it serviced. If not, see if the costs involved are even worth it. Something within the hardware sounds like it caused a chain reaction and has affected more than just the battery.

Yesterday my battery ran dry and the notebook shut down. It will not restart now, even with a charger battery and AC power. Do you have any suggestion?

In regards to your notebook not powering up what sounds like is happening is the system got stuck in suppend mode when the system lost power. So what you will need to do is remove the battery from the system and unplug the ac adapter from the system as well. Next hold the power button for about 10 to 15 seconds. The will clear any power the capacitors may have stored. After you have done this plug in the ac adapter only and try to power the system on. The system should boot. After it does power it down again. Next unplug the ac adapter and put the battery back in. Now you should be able to use the system normally again. Note you will need to charge the battery backup.

Let me know if you still have trouble and/or if you have any other questions.

Backup you files and documents to DVD then reload Windows using the restore DVDs or CDs the notebook came with. This will solve your space issue as well as your mass storage controller error.

Also sounds like you may need a new AC adapter and battery, both should be faily easy and inexpensive to purchase on eBay. Just search by you Acer model number and both the AC adapter and battery should show up. I would at least get the AC adapter, sounds like there is a break in your cable. I got one for my wife's Acer for under $30.
