Defect / fault:
Difficulty Or Inability To Turn The Acer Extensa 5630
Details / symptoms:
When you turn off works perfectly but if you sometimes find it hard to go on.
After a simple reboot on power often no signs of life.
Usually this defect occurs suddenly, even if you use just the PC. Then the defect tends to increase up
to when you can not turn on the handset.
Sometimes when you press the power button you notice only the ignition briefly led the reader / writer,
then no other sign of life: pc remains off.
Note: These symptoms are specific and have nothing to do with other ignition problems (video card, overheating, electrical problems) in which there is usually also some other sign of life as the fan that activates Cmq: in these other cases, the procedure will not work. But it cmq worth groped.
- Unplug your laptop battery, disconnect the power supply
- Press and hold the power button for 20 seconds to discharge the capacitors electrostatic
- insert the battery and try the ignition.
If the first solution does not work (90% does not work …), it is necessary to intervene on the motherboard, disassembling the entire unit.
The solution is to remove a resistance called R138 (see figure).
After this removal, 90% will return the PC to work properly.
In case of further failure, you must replace this instead R138 with a resistance of 4K7 (the original is 1K).
It seems incredible … but this model of computer practically stops working for a resistance … although maybe in three years you have it turned on you and not 10 times … Personally I had to remove only the first resistance, and the PC it worked without problems.
