Please respond Acer doesn't want anything to with me because the laptop is no longer under warranty.....great customer service Acer, especially after I spent $300 plus on getting them to install a HD monitor. Thieves!

    Acer Aspire laptop model 7551 2747 no power with or without battery.?
    Step 1 ; Plug ac adapter into wall outlet only (not laptop)
    Step 2 ; Green LED indicator is "LIT UP" on ac adapter ( power output reading 19.7 volts)
    Step 3 ; Plug into laptop (with or without Battery in no beeps, lights, NOTHING)
    Step 4 ; Green LED on ac adapter goes off
    Step 5 ; Disconnect from laptop
    Step 6 ; Remove from wall outlet
    Step 7 ; Re-insert into wall outlet
    Step 8 ; Indicator LED on ac adapter "LIGHTS UP" ( not plugged into laptop)
    Step 9 : Intentionally "short" ac adapter plug and green led goes out
    Step 10 : Again, remove from wall outlet, re-insert into wall outlet, Green LED lights up, 19.7 volts
    Checked Fuses on motherboard, all good
    Checked adapter plug at board connection, good
    Removed monitor,HDD,Ram Cards,DVD Drive still no power
    Fan works (removed and tested externally)
    Tried removing Battery,holding POWER Button down for 30 sec, did not work
    Need to know where the Voltage Regulators are on this board JE70-DN MB 09929-1 48.4hp01 (or o1).011 or(o11) Dual Core AMD (p320) Athlon 2.1GHz

    Good day

     

    Acer does not provide motherboard schematics. If the mainboard is dead, you need to either replace the mainboard or consider purchasing a new machine if it will be uneconomical to repair.
