i'm using an armada m700 laptop, i noticed that its getting hot whenever i am using it and it is also hanging. I also noticed that the fan is not functioning thus it hangs when it is used for 30 minutes or more. I disassembled the laptop and put thermal paste on the heatsink, but still i got the same results....just the three lights on the panel (capslock,numlock...etc) the hard disk and power LED is also blinking....Need some help pls......Thanks.

Brief expert follow-up tied to the thread: has already tried a cooling fix and recommended professional service. When a laptop will not complete POST after basic swaps, the fault commonly lies with power delivery or the logic board rather than a single replaceable fan. The steps below focus on isolating the problem so the owner or a technician can decide whether repair or replacement is appropriate.

A practical diagnostic sequence: remove all nonessential peripherals (HDD, optical drive, PC card/WiFi, PCMCIA) and attempt a minimal POST with only the battery/AC, one known-good RAM module, and the power button; try an external monitor to rule out the internal LCD. Reset CMOS by removing the coin cell for several minutes or using the BIOS reset method. Visually inspect the motherboard for bulging capacitors, burnt components, cold solder joints, or discoloration. With care or by a technician, check standby and main power rails at the DC-in and board test points (typical checks: presence of 3.3V standby and main 5V/3.3V rails) and listen for POST beeps/LED codes and compare them to the service manual. If no standby voltages appear or rails are shorted, the power regulator area or MOSFETs are suspect; if voltages are present but no POST, the southbridge/northbridge or CPU may be damaged.

If damage is confirmed, weigh repair cost against laptop age. Data recovery can be done by removing the drive and connecting it to another PC. For safety and to avoid further damage, ESD precautions and professional diagnostic tools are recommended before any board-level soldering or power-rail probing.

If the fan isn't working, then a new coat of heat sink gel won't do diddly squat.
You need a new fan. Fairly quickly.

Make that very quickly.

thanks for the reply. I was able to replace the cpu fan but got the same results. I still have the three LED's on upon switching the power and HDD LED is still blinking..... still no display on the LCD. Hard disk is not runing either,

Then I'd suggest taking it along to your service tech. The HD has probably been damaged from overheating, and you will want to get the other components checked too.

So your laptop isn't working at all now?

yup, it isn't working at all. I also tried other working HDD's but still no go. i was able to go to the compaq opening screen once then it suddenly turned off while doing memory check. Do you think there's something wrong on my connections? tnx.

Your connections aren't the issue. Your mobo components have probably been damaged by excessive use without the cooling fan. You need to get each component checked, which is something which cannot be done through a forum thread.
