Power cannot be turned on on Aspire R14

GerojeGeroje Posts: 6Member New User
I opened the back cover of Aspire R14 to replace the HD with a SSD. After I installed the new SSD and put the back cover on with all the screws, the laptop could not be turned on, regardless if I used internal battery or power supply plugged in. When the power supply is plugged in, the right LED light in front is ON with solid blue light. When the power supply is unplugged, the light turns off. Regardless of power supply connection, when I push the power button on the side, the left LED light in front blinks in blue color, nothing else happens. If I hold the power button for about 4 sec, the left LED light is turned off. It dose not affect the right LED light. I checked all the connections on the PCB and didn't find any issue. I tried to press the battery reset button for 5 sec or longer on the back. It didn't help.  I also re-installed the original HD. Power still cannot be turned on. How to trouble shoot and fix it? Any help is appreciated. Thanks!

    Can you try to operate the system on a non-conductive surface with the back cover off and original HDD installed? Jack E/NJ

    I tried it and it didn't work. Same symptom.

    Not good. What is your full R14 model number. It's possible the left blinking blue has an error code meaning. Is it a steady blinking blue with no code pattern or is there some pattern to it, like 2 blue blinks followed by a pause, then another 2 blinks? Jack E/NJ

    I believe the full model # is R3-471T-59UL. SNID is 51410664276. The blue light blinking is steady, a flash about every 4 seconds. Before I opened the back cover, the machine worked perfectly without any issue. I just used Samsung migration software to backup the HD to Samsung EVO860 SSD before replacing the HD.

    (1) Unplug charger.
    (2) Unplug mainboard battery connector
    (3) Remove the HDD.
    (4) Remove CMOS coin cell next to the HDD bay.
    (5) Allow system to set this way for about 30 minutes.
    (6) Then re-insert the coin cell and plug battery connector back into the mainboard.
    (7) Leave back cover off and do NOT install the HDD or SSD
    (8) Try to turn the system back on an insulated surface.

    Do you get any BIOS error beep codes or LCD screen activity?

  • First test the tips of @JackE! Then check that the interlock button (black) is pressed down. You will see a bulge in the lower case that presses this button:

    The white button is the one that resets the battery!

    Good point egydiocoelho  That may be the problem. Jack E/NJ

    I followed JackE's instruction. It did not work either. When pressing the power button, still the steady blue light blinking, no change. No CPU response, no screen activity, nothing except for the flashing blue light. The motherboard does not have the interlock button as shown in the egydiocoelho 's picture. 

    I did noticed the two red lines on the battery power connector were pinched by original factory installation. By wiggling the lines, I made CPU fan to run for a few seconds and then stopped. No other responses. Could it be broken power cable to the battery? How to measure? BTW, how do I include picture in the message?

    >>>I tried to press the battery reset button>>>

    Can you try to find where this switch button is located on your particular mainboard? With the charger and battery unplugged, this spring-loaded normally-on switch might not be making good contact in the up position. Try pushing it down with your fingernail and letting it "snap up" a few times to make sure its contacts are closing. Jack E/NJ

    New thing changes a little bit. I disconnected and reconnected the battery several times. The fan now turns on at the same pace as LED flashing. When the blue light is on, the CPU fan turns on for a couple of seconds, then stops. When the blue light is on again, CPU fan is ON again then off until next blue light flash. 

    I tried to push down the battery reset button a lot of times. It didn't make any change.

    The system is either isn't getting enough power from the battery to stay on --- or it's drawing too much power and being tripped in on/off cycles. If you have a multimeter, it'd be good to check the open circuit voltage on the charger output plug between its outer and inner connectors. If the charger label doesn't say otherise, it should be about 19v. Jack E/NJ
  • It would be interesting to inform you the exact model of the notebook! Example v3-571!

    egydiocoelho  It's an R3-471T-59UL   The mainboard doesn't seem to be the same as pictured in the specs with that missing interlock button. Jack E/NJ

    Interesting. I disconnected the battery from MB for 8 hrs and then reconnected. Also, I uninstalled and installed the RAM. Now the laptop is powered on and running like a charm. The SSD works just like original HDD but faster. Maybe RAM connection has some issue during back cover removal. Thanks JackE and 
    egydiocoelho for help!
