Hi there, my acer extensa 5630ez won’t turn on.
Only by removing the battery, power supply and cmos battery it turns on with only the power supply.
However when it is on state and add the cmos battery, turning off by power button it stays off, only when the cmos battery is removed it starts directly when the power supply are plugged.
Can you give a location of R138?
Is it on the easy side? E.q. the side of the motherboard wich is accessible by removing the bottom plate? I see Q24, located close to CPU. If possible, post a picture of R138, with some components visible.

great.. thank you guys. its working
Hello all Extensa 5630EZ owners with intermittent power on probs! I have just completed this repair and it has also been successful for me. Basic steps taken to repair:
1: remove ALL power/battery and ALL peripherals
2: remove bottom DIMM cover
3: Remove middle cover (this is the long plastic cover over the speakers, the power switch is part of the assembly). Remove power switch connector at the power switch end. Put middle cover to one side.
4: Remove Keyboard by removing 2 screws at top and gently prying the 4 tabs loose, then remove ribbon cable from MB (this connector requires you to slide the brown tab forward to release the ribbon cable)
5: Remove LCD screen (you don't have to physically disconnect the WLAN antenna cables. I couldn't see how to from the top so I left them connecting the screen and body and just manipulated the screen

6: disconnect the ribbon cables for the quick launch buttons connector, mouse buttons and trackpad connectors and then the normal speaker connector.
6: Flip laptop over and remove 14 or so screws from bottom side, then flip back upright and pry off the top cover carefully (in case you've forgotten to disconnect any switches!).
7: Desolder R138.
8: Reassembly is a reversal of disassembly.
9: Switch laptop on and enjoy!
Thanks to the OP, great fix for an otherwise decent laptop.
Hi there ! Lots of thanks for your info ! Laptop works fine,now.b0b
This also worked for a laptop I had in from a client. Left the resistor of. How you found this solution without having the circuit diagram for the motherboard is a mystery to me. Well done!

Just like to say a very big THANK YOU to mrxx74!!! Been having this problem for weeks. Tried all sorts of other fixes to no avail. I then saw this solution, so I removed the R138 resistor and hey presto, I now have a fully working laptop. Pure genius!!!
yo man i wanna know if it works and if its safe.....its not like I dont belive you xD....what i dont wanna screw up
Many thanks this solution. It's great, it's good!!!! I removed the R138, and my notebook always power ON!! Thanks..

You would need to replace the cmos battery first to make sure it's not a cmos battery issue. I dont care if you think it's brand new just go get another one. Its been known that Acer notebooks are picky with certain cmos batteries or atleast half dead ones and will not turn on if they are.
Also make sure your ram is poperly seated because that may me another reason why the notebook will not power on with what it needs to work with.

woow
the remove of the 138 resistor was awesome .
:)
Worked 100%
Thanx
The removal of the r138 resistor worked a treat :-) I didn't use a soldering iron i just took a very small craft screwdriver, placed it under the resistor and prised it off.
Many thanks.
Thank you mrxx74, I have just removed the R138 from my extensa 5630ez and now it turns on fantastically and brilliantly, thank you again so much.

Thanks a lot mrxx74, your solution worked perfectly.
But how on earth did you find that R138 was guilty ? It's amazing !
I found many explanations to access the motherboard here :

Thanks again for having saved my laptop's life.

Hi i've tried mr.xx74 solution and in the first few days it went well, it turned on with no problems, the only thing ive noticied is that the power button LED didn't turn on green, but for me it was no problem. But suddenly it stopped, it won't turn on again and i don't know why, above is mentioned problems with the CMOS battery...can it be the problem?
Many thanks in advance

I cant find the R138... Plz help

If it were the RAM I would expect three quick beeps...
since I didn't hear anything at all I would suspect the CPU didn't come up at all....
Then again the battery doesn't normally unhook the CPU.....

Thanks a lot for the details.....fixed my laptop also.
Cheers.....

Hi there,
I just want to give credit to mrxx74 for finding and sharing the brilliant solution of this problem which worked for me too for an Extensa 5230E
Great job! Thank you
Hi, I removed the R138 on 5320e but still the laptop wont boot. the RAM is OK.

Thanks for the suggestions.
The old cmos battery was 3.04 volts; however I have tried a new one who gives the same result.
Memory module is properly seated and also tried another one.
Personally I think it?s some mobo problem, because by volt measuring of the power switch it?s reacts deep in the circuit of the motherboard.
Also, when I try several attempts to power it up, sometimes it starts up.
Another finding is that when the notebook is in sleep mode it starts up by the on button, only by shut down it failed.
Solved,
Remove at the bottom of the mobo R138 (1K near Q11, near the fan) and see if it start normal.
If so change R138 to 4K7
Hi. For an image, see... http://img526.imageshack.us/img526/105/a...
Remove the r138 and see if its start, if so leaves it away, (in my case that was the best solution).
There are always other possible situations which the notebook refused to go such as.
1. The memory module.
2. Cmos bug (reset it by removing the Cmos battery).
3. Battery pack is defective.
Of course there are other possibilities such as a button that sticks.
Examples are the sleep mode button, on / off button and / or lid switch.
The solution I have given applies only to the symptom.
Only by Removing the battery, power supply and cmos battery, it turns on with only the power supply.
If that does not work, then there is something else going on.
Try it without the above, but so also without hdd etc.
Good luck.
