Question about Dell Inspiron 5160 Notebook

1 Answer

Power on immediately powers off

Not sure what the heat sink is and that might be my problem. Because when I took out the fan assembly, the CPU came with it. I didn't try to separate the two. I assume they shouldn't be one unit. Should they come apart easily?

Power supply was shuting down after a while and now it will only power up for a few seconds. If i unplug the power cord for about 5-10 minutes system will come on for about 5-10 seconds.


This may be a bad power supply or an overheating problem. be sure the cpu cooling fan is spinning and you don't get, possibly, a siren tone from the computer (usual warning of over heating) Make sure the heat sink cooling fins aren't clogged with dust and that the heat sink is attached to the CPU correctly. sometimes a clip breaks and the sink loses contact with the chip. if this happens, the chip will overheat almost immediately.
good luck

My laptop powers on and right back off


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.

Computer shuts down by itself


There can be many reasons of unexpected shut down of your system.Below are some remedies to solve it

1
Run an anti-spy ware and anti-virus utility to make sure that the shutdowns aren't being caused by a malicious program. If the shutdowns are infrequent, install a CPU temperature monitor utility to keep track of the CPU's temperature. If the CPU is overheating, or the shutdowns are frequent, then you will need to troubleshoot your computer's internal components.

2
Check any recently installed internal components to ensure that they are properly connected to the computer's motherboard. Make sure any new expansion cards or memory modules are securely seated in their slots, and ensure that the power and data cables are properly connected to any new drives.

3
Check for large dust buildups on your CPU fan. If the fan isn't effectively cooling your CPU, the overheating CPU will cause your computer to power off. Carefully pick away large pieces of dust with your fingers, and then spray the CPU fan with a can of compressed air to remove the rest of the dust.

4
Reapply the heat sink compound between the CPU and heat sink if the computer continues to turn off unexpectedly. Heat sink compound is a pasty substance that fills the space between the heat sink and processor, which increases the heat sink's ability to absorb heat from the CPU. But worn heat sink compound won't properly redirect heat away from the CPU. Power down your computer, disconnect its power cables and open the case. Unplug the CPU fan's power cable from the motherboard, remove the heat sink and fan combination from the CPU, and then apply the heat sink compound to the CPU--refer to your product manuals for details on reapplying heat sink compound.

Thanks .
Have a great day.

Pentium D problem


Hi oilian,
Be glad it did shut down. If it didn't, your new CPU could haveover heated. There are a few reasons for a CPU to over heat.
1.) There is no thermal grease or too little on the heat-sink assembly.
2.) The old thermal grease was not removed or the old thermal tape was not removed.
3.) The heat-sink assembly was not cleaned completely with alcohol before applying new thermal grease.
4.) The CPU fan is running too slowly.
5.) The heat-sink fins are possibly filled with dust build-up & the CPU fan can not cool the heat-sink assembly. Boot to the bios & go to Hardware Monitor. There you can check voltage, CPU fan speed, CPU temp & other bios monitored settings.

Good luck oilian!

Wont start up


my wife has a presario that had a similar problem - it would boot up, then immediately shut down. I took off the side plate and blew off some of the dust inside. that worked for a couple of days then the symptoms returned. I took it apart again but this time I removed the cpu fan and the cpu heat sink. I cleaned all the **** off the fan and the heat sink and replaced it. this time it stayed on. I checked out the power supply. compaq installed a very cheap power supply - only 250 watts. a replacement power supply for the same machine but with an output of 300 watts is available. as soon as I can scrape up the change, I'm gonna change the PS
