Think it keeps overheating


This could be one of many possibilities. Check all your fans, too make sure they are running, especially if your CPU has its own fan, and you have good open ventilation around the cabinet. If someone has tweaked (overclocked) the CPU you could boot into the BIOS and use the factory default settings to undo any tweaks. You could also re-seat the CPU heat sink (rarely needed), which requires a tube of CPU heat sink goop and careful cleaning to get the old goop off. If you have open vent space, you could add another fan to the cabinet, close to the CPU area. Good luck.

Overheating amilo


Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

While plugged in to power laptop tfreezes and turns off and on during startup....on charged battery starts ok..battery goes flat , plug power in laptop shuts down


Maybe your laptop is overheating. Does it power back on immediately when you were using the power cord or do you have to wait and let it sit a while to cool off before it powers back on?

Do you hear the fans running when you power on the laptop?

Laptops overheat because of:
1) Dust around the vents, CPU and Heat Sink. Dust inside the laptop.
2) A Fan that is not working
3) The Thermal Paste around the CPU and Heat Sink has dried up or is too thin to keep the laptop cool.

How do you replace the fan on a Fujitsu s2210 laptop?


How to Replace a Fujitsu LifeBook S2210 Fan
1. Follow your laptop owner's manual and assembly guide carefully as you disassemble the laptop. Touch something metal periodically to remove static charge, and work on a large table with a bright light source.
2. Turn off the laptop and unplug it. Remove the main battery, DVD drive , Ac adapter and the hard drive. The hard drive is usually located in a slot on one side of the laptop. Remove the screw that holds the cover in place, then pull out the hard drive, screen sled.
3. Turn the laptop over and remove the screws on the bottom that hold the keyboard in place. Flip the laptop over, open it, then lift the keyboard up and out. Unplug the flexible ribbon cable that connects the keyboard to the motherboard.
4. Remove the screws that hold the laptop keyboard bezel and palm rest in place. Carefully pry loose any plastic snaps on the sides, then lift the bezel and palm rest up and out.
5. Unplug the Fujitsu LifeBook S2210 CPU Cooling Fan. Remove the screws that hold the heat sink and fan in place, then remove the entire unit from the laptop. Remove any thermal compound residue from the bottom of the heat sink and the CPU.
6. Apply a thin layer of thermal compound on the CPU, then replace the heat sink and cpu cooling fan. Replace the screws, plug the Fujitsu LifeBook S2210 Fan back in, then reassemble the laptop.
7. Plug the laptop in and turn it on. After you use it for a few minutes, you should hear the new Fujitsu cpu cooling fan running and feel warm air blowing from the vent on the side of the laptop. A Fujitsu LifeBook S2210 Fan does not run continuously, so don't be concerned if the Fujitsu LifeBook S2210 Fan shuts off periodically.

My Advent 5712 closed down whilst I was on line and will not restart. The green light indicating fully charged battery comes on when replugged into the mailns then goes off when I press the on switch and...


Remove battery and try on mains only first, if it runs ok, the issue is with the battery
Then replace battery and run on battery only, no mains.If this works and does not cut off instantly, the battery is probably ok.

There could be an issue with the charging circuit, however, from what you describe, the problem is more likely to be with overheating. Give the laptop time to cool down and remove the battery, then the large inspection hatch over the CPU and fan and with a small paintbrush, remove any dust or fluff that has built up. If it is truly clogged, seek help to remove the CPU and fan (uness you feel confident enough) and clean thoroughly. Regrease the CPU with thermal paste and re-assemble. If the laptop now boots, thjis was the problem, if not, then it is possible that overheating has damaged the chip / graphics chip.

If when you inspected the fan there was no build up of dust, overheating is unlikely and the fault is on the motherboard

Cannot get command promp screen activated on siemens fujitsu amilo li1705 for restore?


Hi there.
I thinks the recovery is on a partition on the hard drive, restart the machine and hit F8 as the PC is booting up, I'm sure the Fujitsu recovery is in that sub menu.


Good luck and thanks for using FixYa!!
