Lg laptop not power on only blinking 16 times then stop green led indicator light on when i press the power bottom it will not turn on and green light indicator goes out.?


Did you try a hard stop? Hold the power button down for five to ten secs until all functioning stops, wait five secs then try to power it back up? I'm no laptop expert, but that has helped me a few times here and there.

What is the center pin used for on the HP 3710b business notebook?I am using a IGO aftermarket power adapter that has the three pin connector tip with center pin like the one DELL uses.Checked with volt...


so what is the full service tag data?
3710b or 6710b, you posted both , and is not complete at all those numbers, (vast submodels exist)
the former number dont fly..

if the PC run ok, on AC pack (HP spec, pack) no battery installed then it (pack) and the PC are ok (no bad jacks)

leaving 2 things, battery (that love to fail) or the charging chip you can not unsolder, ever and replace.

the center pin, seen on the schematic
https://elektrotanya.com/hp_compaq_6510b_6710b_inventec_dd1.0_dosxx_dunkel_1.0_rev_a02_sch.pdf/download.html


or is the AC line loss early warning. (tells PC to go to battery early)
this signal ends up on the charge chip
called Charge Control line.

the schematic is free.
have no battery pack schematic that drives this pin
but its tells the PC to go to (battery early, as power fails AC)
the changer over is not instant
so they this pin tells the PC early, the power is failing
my guess, it can detect power loss, in the pack, in 2 milliseconds flat. (power loss early warning)

Remove the battery and try to power it. if this fail, them change the memory and then the processor if this also fail then one of the power chips on board is bad (also check the power connector if is not soldered properly.

No power


there are six screws in the base and two in the back of the unit. After taking off the top I saw a red button on the front that was a little pushed out - I pushed it in and I got the led lights back :)

Will not turn on, no lights at all


Try to remove the battery, and plug it into the wall. If it then boots, your battery has failed. This happens frequently. If it still wont boot you will need to take to someone to see if the board has died or other issues. Hope this helps
