This is not something that I believe the average joe can do aYoiu need to have it serviced. the fix is below and i amn sure you wil then understand why I said get a tech.
Cause #1
1. Red status LED, self-diagnosis error 44, check for open F9A06 on the
Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self
diagnosis error 34. Check for 5-volts DC at J-9 connector pin 1 and 2
on the Engine Driver PCB if missing replace the Power PCB part #
930B921002 3. LED stops blinking after 70 seconds of plug in but will
not power on. This model is equipped with a keyboard lock feature, this
can be mistaken as a no power condition. To unlock the keyboard press
and hold the "menu" button on the front panel for 10 seconds 4. LED
stops blinking after 70 seconds of plug in but will not power on. Check
for 3.2 volts DC at connector LE pin 3 and 4 on the Control PCB, if low
suspect problems with the switches/buttons on the Control PCB part #
935D776001 5. LED stops blinking after 70 seconds of plug in but will
not power on. Keyboard is not locked and key inputs at connector LE pin
3 and 4 check good. Suspect the E2P PCB part # 934C121001 6. (LED does
not stop blinking after plug in) Disconnect the USB connector from the
card reader to the front from the Chassis, if the LED stops blinking
after 70 seconds replace the Card Reader part # 299P271010. 7. (LED
does not stop blinking after plug in) Disconnecting the USB connector
from the Card Reader did not help. Remove connector FC from the FMT PCB
and plug the unit in, if the LED stops blinking after 70 seconds with
FC removed suspect a problem on the FMT PCB (part # 930B924002), if the
LED keeps blinking with connector FC removed suspect a problem on the
DM PCB (part # 934C116002). 8. (LED does not stop blinking after plug
in) On the DM PCB (part # 934C116002) check C81A2, C81A3, C81B3 and
C81B4 (1000 UFD, 16V, 105C), if any are bad, replace all of them with
part # 181P734030 (680 uFD, 16V, 105C). See Service Tip VS-78A 9. (LED
does not stop blinking after plug in) On the FMT PCB (part #
930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 UFD 105C),
if any are bad, replace all of them with part # 181P734030 (680 uFD,
16V, 105C).
Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:
