Windows 7: Help - not good with computers. Troublesome battery on laptop?

Help - not good with computers. Troublesome battery on laptop?

Hi there,

First off let me apologise. I am RUBBISH with computers.

I have an acer aspire 5535. Its about 2 years old. I installed windows 7 about a year ago. I have noticed a couple of problems just recently.

First off, I noticed my laptop was not holding its charge for very long when unplugged. (I must admit I used to keep it plugged in over night which maybe why it is so worn out now).

I then began getting notifications telling me I should consider replacing my battery.

I now have to keep it plugged in when I want to use it. When I unplug the charger the battery life lasts for 5 minutes - literally.

The battery symbol at the bottom right has a red cross in it and when I hover it tells me to replace my battery.

Also I find that it overheats quite quickly now and it gets quite scarily hot so I tend to turn it off now and again to let it cool down.

Is this just a simple case of getting a new battery? Does anybody know where I can get one from? I don't want to buy a random one of the internet because I really don't want my laptop to break.

Also

Earlier today I was looking on the internet trying to solve the problem myself. I noticed on a website somebody having a similar problem and somebody had replied telling them to run command prompt. I followed the instructions for an "energy report". On command prompt it told me energy efficiency problems were found. 4 errors, 8 warnings and 15 informational. I then opened the .html. and this is what it told me:

jodie7777,
Welcome to SF. Two years is a short period of time to be needing a new battery but not so crazy as it being your only real option. Check with Acer and see if there are any recall issues or problems being reported on your series of laptop. The heat concerns me as the cells are not taking a good charge and just creating heat. If Acer has no discounted/warranty recommendations then you will need to replace it or leave it out while running on AC power.

Don't know if this will be of any interest to you, but I came across it when googling for an unrelated problem -

Two years of battery life does not seem like such an unreasonably short time to me at all. I purchased a 12 cell (supposedly "long life") battery for my HP Pavillion dv5t, and it only lasted about a year and a half.

So, if it turns out that after your research, you find that the battery is just dying, the question then turns to how you're going to replace it. If you don't wish to pay the full price and purchase the replacement from the manufacturer, there are cheaper alternatives, but be careful! I purchased a new battery on EBay, that was supposed to be the exact HP battery (with the same part number - but at about half the price) that I needed, but apparently it was a knock-off because the darn thing didn't fit in my laptop properly. The short version of a very long frustrating story was that, having purchased it from an Asian seller (I'm in the US), the shipping costs and red tape for the replacement battery became so expensive and cumbersome to deal with, that I ended up keeping the darn thing and just taping into my laptop with duct tape. I've had it taped into my laptop that way for about a year now and it's still working --- but very ugly to look at.

I'd honestly get a new battery. But just for desperation's sake, I'd also try any of the following. It's about battery recalibration:

(I)
1. Disconnect the AC adapter from the laptop.
2. Remove the battery.
3. Press and hold the power button for about 30 seconds then release it. (You will not see anything happen)
4. Connect the AC Adapter to the laptop. Make sure the AC Adapter is plugged in.
5. Turn the computer on as normal.
6. Once Windows loads, insert the battery.

(II) Note: Do not use the PC during the calibration cycle.
1. Shut down the notebook PC.
2. Connect the AC Adapter and charge the notebook PC until the battery charge light is green, indicating that the battery is completely charged.
3. Turn on the notebook PC.
4. Press F8 several times when the Acer logo appears.
5. When the Windows Advanced Boot Options menus displays, use the Up and Down arrow keys to select Safe Mode and then press Enter .
6. When the Windows Advanced Startup Menu displays, select the Startup in Safe Mode option.
7. Disconnect the AC power adapter from the notebook PC.
8. Allow the battery to discharge completely until the notebook PC shuts down.
The battery is now calibrated, and the battery level reading on the power meter should be accurate.

(III) Note: Calibrate the battery while PC is in use.
1. Connect the AC adapter and allow the battery to charge to 99% - 100% of capacity.
2. Disconnect the AC adapter from the notebook PC.
3. Click Start and type Power Options in the Search field and press Enter .
4. Select Create a power plan from the left sidebar.
5. Click in the Plan name field and type Calibrator . Then, press Enter .
6. Select Never for all topics in the On battery column.
7. Click Create to accept the values and force the battery to consistently discharge.
8. Allow the battery to discharge completely until the notebook PC shuts down.
NOTE: The battery power meter is now calibrated, and the battery level readings should be accurate.
9. Connect the AC adapter and restart the notebook PC.
10. After calibration, return to the Power Options dialog box (Step 3) and select your default power plan setting.

I would replace the battery and also blow the dirt out of the box (with compressed air). When you have the battery constantly attached while on main power, 2 years is the lifespan you should expect.
