When it crashes, does it happen at the same spot? Does it get into the OS or are you looking at a hardware monitor in the BIOS to get your temp. Was the heatsink replaced because it was doing the same thing before? I'm not sure overheating is the cause since 158F is only 70C and that's not hot enough to cause a shutdown. T-Max on the almost all CPUs is 100C.

SOURCE: it crashed and now it automatically shutdown after a minute about

The fan may be cluttered with dust. Clean it. Then turn the unit on and watch to see if the fan does indeeed work. If it does not, shut the unit down till you get a replacement fan. The fact that the unit shuts down is a saftey feature to keep your Proceesor from being damaged.
If cleaning it works, your processor should be ok.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

SOURCE: Hello.

It could be that there is a build up of dirt blocking the flow of air on the cpu fan. This would require you to take apart the laptop and physically take out the big clump of dirt.

That would be the next step and if that was already done and the laptop is still overheating then the motherboard is going bad on it.

SOURCE: laptop not booting

Putting it in the freezer is NOT a good a idea. Thats a good way to kill the lcd screen. That will cool off much faster than the internal parts and as soon as it gets too cold, poof its gone.To actually get the cpu and board stuff cold would take a few hours as the enclosure is actually going to insulate the internal parts.

If the laptop is overheating then the air at the exhaust will be just warm or more. You may feel a hot spot about where the cpu is on the bottom. It takes very little dust to cause overheating. Unless it has already damaged the cpu then it should take several minutes to heat up enough to show symptoms.

It is possible the ram modules are either loose or failing. Thats easy to eliminate as well. Take them out and put only one back in. If it works then it was either a loose or poor connection or it is the module itself. If you have more than one take the first out and check the second to be sure. If it is ram the problem should be in the #1 module as that is what it will boot on. It won;t see the second one until you begin to use the laptop.

Ok 2 things are likely your the heatsink (the copper part of your computer that gets hot that you can see trough the grill) is blocked with dust try and clean it out with a vacuum or use a thin piece of plastic to poke it out, or your fan is broken.

can you see or hear the fan spinning? if it is then it is dust, CLEAN IT WOMAN!!!

Cooling fan speeds then cpu shuts down


That would indicate overheating ... do the usual checks = blocked vents, dust clogging the CPU heatsink etc ..

Then the less likley, such as a loose fan cable, loose CPU (or other) heatsink etc. (you might want to reseat the CPU heatsink ...)

Still no luuck ? Well, it's time to start unplugging things .. reduce your system to the minimium, maybe some plug-in card is upsetting things ..

If 'none of the above', then it's possible the power-supply is sending incorrect voltages or the motherboard has failed in some way (eg the temprature sensor under the CPU chip)...

PSU's are cheap, so replace that before replacing the motherboard

My lapi hp G62 turns off sudenly ..while on the main power power the white light still stay indicating that the lapi is still on...i dont know why is this happening?


The CPU may be shutting down because it is over heating.
If you are notusing your laptop on a flat surface, it may be obstructing the cooling vents onthe bottom of the laptop. Your laptop fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust. A laptop fanassisted cooling pad may solve your problem

Hp 2730p fan noise


Laptop Fan noise:

This seems to be a common problem with laptops over a couple of years old. Dust gets trapped in the copper fins and the fan of the CPU heatsink and reduces the efficiency of the cooling, which results in regular power off's by the laptop as it gets over it's upper temperature setting. The fix is relatively easy, just remove the heatsink unit, blow it clean with compressed air, clean the old CPU heatsink paste off with isopropyl alcohol (IPA) and spray a thin film of heatsink paste on the CPU.


If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Jo

What will be the possible cause when my laptop compaq presario C700 is automatically turning off?


If the laptop shuts down and won't boot up until it has cooled down, then the CPU is overheating and goes into thermal shutdown. This is caused by either a faulty fan or the fan and heatsink assembly is clogged with dust.
If this is not fixed then eventually the CPU will fail completely.
Check the fan to see if it spins freely if not then replace the fan.
If the fan and heatsink is clogged with dust then remove the dust from the fan and heatsink fins.

The check engine light on a 2001 beetle read code PO118 engine coolant temperature circuit high input. what do i do?


16502/P0118/000280 From Ross-Tech Wiki Jump to: navigation, search Contents [hide] if (window.showTocToggle) { var tocShowText = "show"; var tocHideText = "hide"; showTocToggle(); } 16502/P0118/000280 - Engine Coolant Temperature Sensor (G62): Signal too High Possible Symptoms
  • Difficulties with starting a cold engine.
  • Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
  • RPM at idle is irregular.
  • With all engine temperatures idle rpm will often vary between 900 - 1000 rpm.
  • With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.
  • Bad acceleration during warm-up.
  • Diesel Engines: Glow plug indicator may be on for a longer than normal time or at ambient temperatures where it shouldn't come on at all.
Possible Causes
  • The electrical signal coming from G62 is too low
  • Wiring and/or connections faulty (short circuit?)
  • Engine Coolant Temperature Sensor (G62) faulty
Possible Solutions
  • Check wiring and connections
  • Check / Replace Engine Coolant Temperature Sensor (G62)
Special Notes
  • In many cars between MY 1995-2002 the G2/G62 had a bad reputation for failing often. The original G2/G62 sensor is black and the improved replacements are green.

How to replace CPU on HP 6735s


Most likely from the back (the underside) where the fan/s are located. You will need to remove the fan/heatsink to get to the CPU. The CPU is locked in place with a zero insertion socket, you need the turn the locking screw 90 degrees to release the CPU.
Be careful when you insert the new CPU, there is a notch that indicates the orientation of the CPU to the socket.
After installing the CPU don't forget to put some heatsink compound on the CPU before installing the fan/heatsink.

Presario 2200 CPU fan appears to be dodgy


Not really, since the fan is controlled ny a thermal sensor on the Motherboard. You may want to start by having the fan and heatsink assembly replaced.
