acer aspire e 11 laptop won't start and blinking blue light

Natsu3567

my acer aspire E 11 won't start when i press the power button it won't there is a blinking blue light 
and some times there is a sound cames from battery or speaker idk pls help

JackE

Press and hold power button until all lights are dark. Then remove charger. Then insert paperclip into pinhole on bottom for 30 seconds. Then plug charger back in but wait for the battery charge light to turn from steady orange to steady blue. Then try to turn it on again.

Natsu3567

thank you for your ansver but it did't help . when i use charcer the orange light is steady but blue light is not affected 

JackE

Is the blinking blue light the battery charge LED or the power LED?

Natsu3567

power led i think cause when i use the charger orange light is steady 

JackE

Wait till charger orange light turns to steady blue before you try to turn it on. This may take several hours. Maybe even overnight. If the battery charge LED doesn't turn steady blue  then the battery has probably failed and  needs to be replaced. Usually about $24USD for most e11 models.

i hope it works thank you

JackE

I'll keep my fingers crossed that it works for you.     Jack E/NJ

it didn't work when i use charger charging light is all blue but the other light is still blinking like before there is no light in screen no sound from hard drive or any sign of living D;

JackE

Did this seem to happen suddenly for no apparent reason?

Natsu3567

actually i gave it to my friend and she said she tried to change harddrive to ssd but she had m.2 so she couldn't after that this problem occured idk what is happened i learned  it 5 mins ago 

JackE

Did it happen before or after yoou gave it to your friend?

Natsu3567

after i gave it to her. she said she removed harddrive and put it back

JackE

That probably explains it. Better check to make sure the hard drive's connector is fully inserted to its mainboard socket.

Natsu3567

everything is in its place but there is no sign of living when i press the power button power led is blinking thats it no light from screen no sound i don't want to think it is dead 

JackE

Reseat the HDD connections a few times anyway to help clean its contacts. It might also be a good idea to reseat all the other accessible components like RAM module if so equipped. If she indeed tried to install an m.2 card, you probably should remove the bottom cover for a more thorough examination of other ribbon connectors to the mainboard. Some of them are rather small, easy to miss a disconnection and use a rather flimsy sliding wedge to keep them in place on the mainboard. Also, it is imperative that the battery be disconnected from the mainboard immediately after removing the bottom cover as live circuits are exposed.

Natsu3567

all the cables are intact hard drive is in its place but it doesn't work

JackE

(1) Was the battery disconnected when trying to install the m.2 card?

(2) Was an ESD wrist protector used when trying to install the m.2 card?

Natsu3567

rn i controlled everything and pressed the power button but there is no change 

JackE

What is full ACER E11 model number? For example, E3-111? ES1-132?

Natsu3567
