Re: system unstable

This could be a couple of things, the shutdown will probably be because of the overheating, check for blockage around fan extraction area. The other could be that there is a virus or spyware running, taking over the processors work and causing a shut down or overheat error, check for both. The other could be a driver conflict, try doing a system restore to before the problem started.

My hp compaq g62 suddenly run slow when power cord is removed and it runs slow too on battery after some time

The processor is designed to gear down when you switch to battery mode to conserve power, this way the rechargeable battery last another 30% longer at least.

Acer 8920 G restarts after 3 min and again shuts down

First make sure your fan is operating on your processor it takes about 3 mins for it to over heat and stop and shut itself down for safety to prevent burning up the processor.if its not this read on.
Also when you boot into safe mode then do a system restore to a date before the problem started. But first in safe mode run your antivirus scan to find something that is missed while being hid behind the operating system while functioning.

Slow shutdown HP Pavilion dv7

There are a number of reasons that may causing your HP computer running slow to shut down or start up, but generally two factors: outdated hardware or poor system maintenance. For hardware part: you can get more RAM, higher CPU etc. For system part: there might be a lot of junk files, caches, errors etc out there, about 80% slow HP issues are caused by this reason, in this case you can rely on to free detect and fix related issues.

When I plug in my Dell Inspiron 1521 laptop, I get an error message saying it does not recognize my charger, will not charge and will likely slow down my computer's speed/performance. Everything...

Same topic on Dell official community, may it will help.

There is high possibility that your adapter is stuffed. Dell have built in a recognition circuitry into the 65w adapters and when that goes, the system will no longer recognize it as a 65w adapter even though it is still putting out 65w. The system then shuts off the battery recharge circuit and to make matters worse it won't even charge the battery when the computer is off. It also speedsteps the processor down to half its speed so everything runs slower. Only option is to stick with a slow computer that can't be used on batteries or buy another ac adapter.

If you do not want to pay $80 for a original adapter directly from dell, there is an alternative choice to get an 3rd party charger, check this link below:

Hello, i have a Acer Aspire 5100 Laptop which i bought in 2007. Recently i have started having problems with HD-Ready videos (720p). before when i use-to play 720p videos on my laptop it use to run...

As you say the laptop handles the video well in the beginning, then when it runs for a few minutes it has trouble rendering the video in sync with the audio.
The reason for this problem is that 720p videos need the Graphics card in the laptop to work hard, this process generates heat and this heat needs to be removed from the laptop or the whole system does what's known as throttle down.

It slows down to reduce the heat it produces, thus preventing damage to the system.

The solution to this problem is to clean as much dust out of the laptop computer as possible, use a vacuum cleaner. Turn the laptop off and remove the battery. Clean the vents, it is a good idea to raise the back underside of the laptop with a pencil or the like. Some-thing that will raise the laptop off the work surface without obstructing the vents on the underside of the laptop. By raising the laptop it will allow for greater airflow through the laptop, therefore reducing the operating temperature of the laptop therefore making it more efficient and responsive.

Your laptop shuts itself down, this confirms that it is overheating. It does this so it does not damage itself.
If it still overheats then you will need to contact a computer technician to give it a good through cleaning. To clean the dust between the heatsink fins. Possibly increase the fan speed or replace the fan.

Take care!

Acer 3050 battery doesn't charge and causes CPU to run at 90%

I contacted Acer about the problem and their solution was to buy a new battery since the computer was not longer under warranty and they really didn't know what was going on! In talking with friends, and checking on-line, the consensus is that laptop batteries don't last more than two years. You can keep them charged, let them run down, recharge them frequently: they still will only last about two years.
I just find it hard to believe that Acer has never heard of this problem, especially when I'm reading similar posts on this site.

Anyway, as deviant00 suggested, I got a new battery on for $56. They offered $30 off if I signed up for their credit card. The final cost was $26. The battery came today and the computer works like a charm. I also followed jell587's advice and scanned the computer with the Malware he suggested:no viruses.

The solution for me was buy another battery; expect it to last for a couple of years.

Thanks for all the help.

Acer Aspire 9300-3655: Shuts Downs When Idle

does it just shut down randomly? and then when you turn it back on it shuts down nearly straight away? if so then it sounds like the processor is overheating and as a saftey mechanism it shuts down. which could be a big problem.

or you just need a new battery. because you are supposed to only charge it when it is dead. if you keep it on charge and plug it into the mains randomly,then the battery will eventually lose it capacitence (basically how much charge it can hold) and then it wont last long atall. you want to hope its the battery.

hope this helps.
