Acer Aspire 4935G Random Shutdowns, Not Charging when turned on

I don't how can i describe this problem detailed enough, But my acer aspire 4935G has been turning off randomly. this laptop has been with me for about 5years now and i suspect that because of the 'age', problems will occur.
I still hope that you guys can help me repair this on my own.

Windows vista, core2duo, 3gb RAM, 512mb video

Here are the problems (mainly about shutting off randomly)

-i will be using my laptop for the whole night and while using, with no heavy applications running, it will just shut off.

-the processor fan is running. (i shared this info because i suspect that its due to overheating.) but will still shut off.

-i already dismantled my laptop just to clean the fan. I removed the dirt. trust me, i really cleaned the fan and where the air is coming out. clean. still shutting off randomly.

-i tried putting a desktop fan under the laptop, not just a usb laptop cooler, but really an electric fan to remove overheating, But still shuts off.

-now here's the weird part, i play NBA 2k13, which we know is a very heavy game in terms of processing and video, and RAM, etc,. If i play NBA 2k13, it doesnt shut off! Ever! but if i do an alt+tab, to go to my desktop, after a few mins, it will shut off. weird, thinking that shutting off will mostly occur while playing games. But no, it doesnt shut off while playing NBA 2k13. (this is the only PC game i play)

-if i go to ctrl panel>power options> "Acer ePower Management", and if i adjust my CPU Speed to "High" and "Maximum", laptop will shut off in few seconds. So right now, my laptop is always running in "Low".

- for example ill be using my laptop for the whole night, in the morning, if i plug in the laptop, its charging, BUT if i pressed the ON Button, the charging STOPS. so imagine, if i dont have a battery inserted in the laptop, it WONT TURN ON, because its not charging.

-now if i put the battery, and i turn on the laptop, it will continue to boot, BUT for as many as 10 tries or more, it wont reach my desktop because the laptop keeps shutting off. AND ITS STILL NOT CHARGING. Hope you guys can imagine.

-now my battery is like dead. it doesnt last for an hour. i think this is a common problem for 5year old laptop batteries. so imagine the problem if my laptop wont charge even with the battery connected. i cant turn on my laptop. i just wish that the battery could hold enough power to complete the boot to windows.

-charging of the laptop or electricity flow will resume in the laptop, after a few mins, only if i make it to windows. I don’t know what triggers the charging. But my laptop will just Start charging RANDOMLY.
So this is like the best condition of my laptop, WHEN ITS CHARGING and NO SHUTTING OFF Occurs.

-everything just starts randomly in my laptop, SHUTDOWNS AND CHARGING. and I cant really find what triggers the SHUTDOWNS and THE CHARGING.

-if i remove the charger, laptop will turn off. battery cant hold the power.

so those are the problems. I rEALLY HOPE THAT SOMEONE READ this. and Help me repair this on my own.
Im not afraid to dismantle my laptop.

what could be the problem? is it the battery? the fan? the charger?
im planning to reformat my laptop, factory defaults or setting. install windows7. but will this help? is this a software problem?
Please help. I know this is still a good laptop.

P.S. While making this post, my laptop shut down TWICE! I have to save this to a word file. Pls Help.

  1. It's not really that easy to say the main reason, it could be the power adapter has a damaged connector or the laptop itself has a damaged connector for the adapater, it could be rthe hard drive is faltering or it's nearly full of data.

    How much free space is on the latop?

    Don't format the hdd, the laptop is specific to Vista only, there are no drivers for Wuindows 7.
  2. Drive C 29.1 GB free of 226GB / Drive D 54.1gb free of 222GB

    wow, didnt know that. about the specifics of this laptop. but i went to acer's website, and found the drivers of this laptop, i can download all of them and i can choose if its for vista or for windows 7. so i figured, this laptop can have a windows 7 OS, with windows 7 vista.

    please enlighten me. thank you for the reply!
  3. I actually dfidn't check for the OS status hehehe ...but at least you know now whether you can actually upgrade to Windows 7.

    29gb free space is less than 15% free of the volume, if you use hibernation or sleep mode, you should consider disabling the auto timer options, disabling hibernation will free up about 10% of the volume. If need to use sleep mode, just do it manually by going to Start (Menu) > Sleep..

    Regardless of the game play, you need a replacement battery.
  4. i bought a new battery, and the problem is still there.

    there's no problem with the charger. we checked it.

    if i put the new battery. without plugging the laptop, the laptop wont turn on. its like the battery cant handle the power needed by the laptop.

    if i plug the laptop with the battery, it will charge. BUT if i turn it on, the charging will Stop. and the laptop will boot. but before reaching my desktop, it will shut down. it will just power off.
    I THINK, the shutdowns happens if the laptop starts loading Windows, because if i just leave the laptop in BIOS Mode (pressing F2) or in DOS (pressing F8 if you like to boot in SAFE MODE), that laptop wont shut off.

    any help please?
  5. Is the output of the charger identical to the label text as stated underneath the laptop?
    For example 19v 4.64a

    Using a Travel Adapter or an adapter not designed for that laptop will cause the capacitors to eventually burst resulting in issues similar to what you are experienceing, you may need to take it to t aservice center for them to assess properly.
  6. yes its the same charger o its the right charger
  7. Is the battery already charged? You can't charge a charged battery.

    Check the options for the battery, there might be an option to disable charging or some other option or other in the battery options dialog.
  8. thats happening to me right now with the same laptop pls help
    but my laptops battery is somewhat like broken cause if i charge it the on button starts to blink then it says not charging then suddenly the laptop dies on the other hand why dosent it work without battery i connect the charger it says "no battery detected " but its still charging then i start to play minecraft and talk to my friends in skype after like 25-30 min im still talking and suddenly it offs like hell that pisses me of

    my question is why dosent the laptop work it has power connected to it ?
    and i tried to buy a laptop cooling fan but it still dosnt work pls reply PLS PLS PLS !!! :ouch::??:
  9. Considering the age of the laptop, it might be past it's "use by" date meaning that it's not up to the tasks that you intend. Try not doing multiple tasks like Minecraft as wel as Skyping, just one or the other. Also, turn off Auto Updates so that the system is not actively searching for updates using the background services. You should only use updates from the Acer site and not the Windows Update services, anyhow.

    Consider whether you are using usb ports fr other devices like charging the phone or something, it's not considered good power management to excessively use the usb ports for things that could be charged with an adapter.

    Dismantling a laptop is not an easy task, I'd avoid that option and leave it for an experienced service person to do.

    What other programs do you have instaled, are they "Vista" compatible or much more akin to XP or Windows 7? Some other OS preferred programs, games, and apps can bog down or use drivers that can degrade the system however, I'm more in line to thinking that you my have mixed drivers rather than totally Vista preferred, you may need to uninstall some drivers and do an update, check the Device Manager for any exclamations or greyed icons.
