Question about HP G70-460US Notebook

2 Answers

I've been keeping the vent clean for my laptop cpu fan, but it seems to be heating more rapidly than usual. I believe I need to check out and possibly replace the cpu fan. I have an HP G70-460US. I tried removing all the back's screws, but wasn't able to get the back off. Can anybody help me through doing that?

You have to take all the screws out from the buttom first, then start your way with taking the front lid off where the power button is. There are few screws there too then the keyboard, then it will all come apart. Make sure you save all those screws in separate section because you will lose the positions where they go and have extra screws left over when you're done. HPs are known for overheating, check HPs website if they have been recalled you might get it replaced. Good luck

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.

Fan not running , cpu very hot.Will that cause the fan not to run and laptop proline m548s switching off?


Oh nooooo !! If your fan never turns on, then get the problem fixed, but please don't continue trying to use the poor computer.
A CPU can get hot in less than a second, and if used without suitable cooling will eventually kill itself. Your computer turning itself off is a built in safety feature, but this usually only happens when the CPU is already dangerously overheating (when I say dangerous I dont mean it will explode or go on fire, I only mean it will damage the CPU beyond repair inside).
Some fans only start spinning when needed to save power/electricity/battery so those types have to wait until a certain temperature has been reached in the CPU before it will start to spin, which can make it appear that the fan is broken.
The first thing to check before replacing a fan is see if its blocked with dust/fluff - for towers or laptops, but laptops tend to be far worse for collecting fluff.
Make sure all fluff is removed from the heatsink area of the fan assembly, it should be completely clean all over - the fluff will collect in the heatsink fins.
If that's all ok (and this should always be done anyway), check that you have some kind of heatsink compound between your heatsinks base and the CPU - this is essential on most computers - the compound helps take heat from the CPU onto the heatsink to spread the heat away - and the fan helps keep the heatsink cooler.
Another thing is, as its a laptop, make sure that wherever you use it, you don't have any air vents being blocked up. Many many users have them on a lap, or cushion etc. and don't know that the air vents underneath are then blocked, causing massive overheating problems soon.
One of my most common jobs is to clear all the fluff from air vents on laptops, so that's what I would check first though. I get many that have a solid wall of fluff insde, some as much as 1cm thick. Some even have damaged CPU's from the heat as the owner has kept turning it on again and again, but actual damage is very rare :-)

When i have it plugged in it will turn on and work for 5 minutes or so and then it will turn off and same thing with when it's unplugged. what the problem?


It sounds like your CPU is overheating. You've not mentioned whether a laptop or desktop PC.

Desktop - disconnect everything, take it outside if not raining and clean out all the dust and rubbish you can, I ( VERY CAREFULLY) use a dry paint brush. Pay particular attention to the CPU fan and heat dispersal block. More or less in the middle of the mother board, try and clean out the metal vanes. Also clean around the PSU fan assembly. Check all cables are good and home. Re-assemble and try again.

If it keeps on, its probably best to talk to someone who knows a bit more, or, as above, remove the CPU fan assembly and heat dispersal plate, clean CPU but leave it in the mother board, also clean the heat dispersal plate, (The goo is heat dispersal grease to ensure good contact between CPU and plate) Replace the grease and re-assemble.

A tip is to connect the power supply just before putting the case cover back on, powering up and checking that the CPU fan is working OK.

You can get loads of tips and videos from You tube.

If a laptop, the clear out the dust in the vents on the side and underneath, if that doesn't work, it means dismantling your laptop to clean it out. Your still trying to achieve what I've described above.

Hi.

If the laptop is getting very hot and shutting down then you no doubt need to clean the CPU fan and the air vents of any build up of dust that may have collected over the 3 years you've had it.

Get a can of compressed air and give short blasts through the air vents and the CPU fan grill. You should see dust shoot out of the vents when you depress the button of the can.

The CPU fan is located underneath that laptop and the air vents can be located at the sides or the back of the laptop.

If it still gets hot and shuts down after doing this then I suggest that you take the laptop to a reutable PC repair store and have them clean the inside of the laptop for you and have it serviced at the same time.


Hope this helps!!!

Gaming (and graphics application) consumes more CPU/ Processor resources and due to the heavy processing the PC (CPU & GPU) heatup. Excessive heatup beyond usual is alarming and PC shuts down by itself when the processor/ GPU temperature exceeds the safe temperature limit. There are mainly two reasons for heatup.
Laptop heating issue generally occurs due to fan failure, which may damage the system, if not checked properly. Another most likely cause of overheating is the dust present inside the laptop, which clogs the fan and heatsink.
1. Make sure the fan is running. (if not it needs replacement)
2. Clean the fan and heat sink (thermal module). Click here for GENERAL Acer Laptop disassembly instructions and refer to
Removing the System Fan/Thermal Module after removing the outer cover. Take out the fan and heat sink. clean them with the help of tooth brush and put it back. Also, repair manual can be searched online or downloaded for referrence.
The procedure is very simple, but if you are not comfortable with working inside electronics, I suggest that you should get you laptop checked by a professional for servicing (if required). I believe immediate action is required to prevent any damage to your machine and data.

Hope it Helps! Let me know if i could be of any further assistance.

The Fan on your laptop is automatic. It starts when your laptop gets warm and turns off when the temperature is lowered. I dont think it needs fixing of any sort.

Laptop won't boot turns on then off after about


Hello,

Your Laptop seems to be full of dust - Maybe your CPU Heat sink FAN cannot turn because if this THUS causing your laptop to heat up and shut down again to prevent your CPU from receiving damage due to high temperature.

Close your laptop lid, then put the unit on its backlcd. Make sure you disconnect the Battery and the A/C Power chord. With the emty battery slot is facing you, take note of the screw that is facing you to the right on the bottom cover. There might be others like this in the same area. The cover that you need to remove is of rectangular shape, and the largest cover.

When you have removed it you should see the CPU Heat sink and a FAN. This is the part where you blow the unit out at that spot with compressed air so that the dirt will no longer block the heat from venting away from the laptop mainboard/cpu.Please check if the CPU FAN is still turning licenly. If it doesn't turn or very difficult - replace .

[ADVANCED]
Then, remove the 3 screws from the CPU heat sink and thereby remove the HEAT sink completely. Remove the CPU Heat sink FAN and clean it as nessesary. Use a small flat to switch the CPU from closed to open and remove it. Then clean it with a cloth and ethanol - make sure you remove all dirt and old heat sink paste on top if it. make sure you do not touch the bottom of the CPU and handle the pins carefully.

When you are done, place the CPU back and reaaply a eyedrop of fresh heatsink paste onto the CPU, lock the CPU switch again. Then clean the backside of the CPU heat sink where it rests on the CPU. When you are done with that, place the CPU heat sink back onto the CPU then screw the 3 screws back onto the CPU heat sink and onto the mainboard. Keep the sequence in mind. Reconnect the CPU Heat sink FAN to power on the mainboard with the cable then place the cover back onto it. Tighten all screws again and reconnect battery and A/C Power chord.

Today i started up my Asus N50V Laptop up and the fan is running continually now, I rebooted it and still no change. It never has done this before?


Hi,

It is normal for the fan to kick in to cool the processor, but it sounds to me like the CPU fan and the air vents need a good cleaning.

Noisy fans and them running for a length of time means that its having to be on more to keep the processor cool.
Other causes of the fan being loud and on constantly is gaming and heavy programs. The more the processor has to work the hotter it will get, thus the fan being on all the time.

Have a look at your air vents and the CPU fan for dust. If you see any dust then you will need a can of compressed air to blast through the vents and CPU fan blades free of dust.

Removing the dust from the machine usually quietens them down.

Hi,
Fans are usually noisy due to a build up of dust that's collected on the fan blades.
The best way to clean them is to get a can of compressed air and give short blasts through the air vents, also turn the laptop upside down and give a couple of blasts the CPU fan grill.
Alternatively you can get a clean, stiff paintbrush to clean the fan blades and blow through the air vents to remove any dust.
The laptop won't get as hot or noisy if you clean the air vents and CPU fan blades regularly.
