| SYMPTOM
1: |
Laptop shows
no signs of life, no lights appear when power
supply is plugged in with the main battery removed. |
|
| DIAGNOSIS: |
Either the internal
or external power supply is faulty - check the
obvious: a)fuse b)if you have a Volt meter -
check the voltage output of any external PSU
is correct & constant. If you find the ac
working then you have an internal PSB (Power
Supply Board) fault. |
| REPAIR: |
Should we find
the fault to be your external PSU then approximate
repair cost will be £50 + VAT. If the fault
is internal then you will be liable to our fixed
price repair fee. 99% of this type of repair
do not need extra parts unless the damage is
severe - we have almost 100% success in repairing
these faults. |

| SYMPTOM
2: |
Laptop doesn't
power on when the power button/switch is switched
on - power led light lights up and not much else
happens - screen does not light up. |
|
| DIAGNOSIS: |
Remove all removable
devices such as: additional memory, battery,
hard disk & try powering the system again
- should you still be unable to make the laptop
work then you have a motherboard or processor
fault. |
| REPAIR: |
Generally this
would be a motherboard fault and requires component
level repair - there is also a possibility of
the fault being a processor fault which would
raise the cost of repair. Approx cost of repair
will be fixed price repair + parts £0-200
usuallly. |
|
| SYMPTOM
3: |
Laptop works
off the mains but will not run from a charged
battery or wont charge batteries. |
|
| DIAGNOSIS: |
Make sure you
have used a new battery - should you find this
battery is not chaging or appears to be charging
but system does not run from it them you have
a motherboard fault. |
| REPAIR: |
Generally this
would be a motherboard fault and requires component
level repair - these repairs may need ICS and
the cost of these may vary - usually no more
than £50 - generally 90% success rate on
these repairs |
|
| SYMPTOM
4: |
Screen appears
very dimm - can vagely make out the image or
cannot see anything on the screen as the system
is switched on - the HDD Led light appears to
be flashing as the system is powered on. |
|
| DIAGNOSIS: |
Press firmly
along the edge of the screen squeezing the plastic
along the edge together - watch carefully for
any changes on the screen - should there be no
changes then it is most likely that you have
an invertor board or a backlight fault if it
was a cabling fault then you will see the screen
appear normal for a short period of time when
pressing aroud screen edge. It is worth pluging
an external monitor into your laptop and using
a combination of the FN + one of the F1 - F12
Keys to output the signal (refer to your manufacturers
users guide) |
| REPAIR: |
Normally component
repair to backlight invertor board sometimes
screen ribbon & sometimes this could be a
faulty light tube. Care though if the screen
is completely black and the laptop has travelled
recently - could also be broken display. - extra
costs don't normally exceed £100. |
