Sir, my laptop CompaqEvo610C can not charging i check my battary on other same model of Compaq it is working and good condition and give backup more then 1hour. when i put the battary in my laptop again...

Since you tried your battery on another pc, then try a different charge power supply on yours. You may have a bad power supply adapter or your battery terminals on your pc may be dirty and need to be cleaned with rubbing alcohol and a cotton swab.

When I switch on the laptop it will not run on mains power ,only battery power, however when i shut down the laptop the battery is being charged correctly,

The power options have been changed,when it's on hover over the battary icon down next to the clock,it should say plugged in & charging if not right click on the icon & select power options & then select an option from the menu on the right,go through them all & change them to suit you or create a power plan of your own.
if this doesn't work then it's because the enpowering tech is controling the system so press the green "e" symbol at the top of your keyboard or on your desktop & select the battary icon the settings will be in their or in the settings tab,just have a look around you'll find it.

Start taking your laptop apart piece by piece and test it after each removed component:
1. Remove the hard drive and test the laptop.
2. Remove the DVD drive and test the laptop.
3. Remove the wireless card and test the laptop.
4. Unplug the display panel from the motherboard/video card and test the laptop.
Continue taking it apart until you have only three major components connected: motherboard (with video card), processor, and memory. If you still experience the same problem, most likely it's bad motherboard.
By the way, before you start, try reconnecting the memory module. If you have two modules installed, try removing them one by one and test the laptop with each one separately

C700 laptop's display problem

I have the same issue. 

Problem appears only while working with power adapter.

When I turn off power adapter (so notebook is working with battary) everything is OK.

It is somehow connected with shutting down. If disconnect power adapter durring shutting down - next time you will have problems with grey screen.

Don't know how to fix it.
Usually solve by making several reboots and to turning on/off power adapter.

Notebook fan

Yes most likely as otherwise you would not have been advised to shut down. The processor get red hot is not cooled continuously by the cooler fan. And heat of all sorts is bad for the health of the processor and other components. What I would suggest is to use a Cooling PAD available on Ebay. This is nothing but a tray that has three USB powered fans that keep dissipating the heat with these three fans all the time the laptop is running. Very helpful. Although you spend some money on it, but in the long run it works wonders.

I should have added that the extra plastic insert thing that comes with the CD holder is used when you want to print on the smaller 8cm disks.

My Acer Lappy turns off automatically!

This could be a heat issue. Make sure that nothing ( eg dust) is blocking the air vents.
