Hi all

I have just been given a friends old laptop that stopped working for him a few weeks ago and would like to fix it if possible.

Laptop is a Hi-grade ultinote m6400.

Spec:

Processor type Intel Pentium 4
Processor speed 1800 MHz
RAM installed 512 MB
Dimensions (WxDxH) 31.3 x 26.3 x 3.8 cm
System weight 3.35 kg
Travel weight (with AC adapter and external peripherals) 3.95 kg
Display size 14.1 in.
Graphics chipset ATI Mobility M6-M
Internal spinning media drives HDD, DVD/CD-RW combo
Hard disk capacity 40 GB
Hard disk rotation speed 4200 rpm
LAN connection Realtek RTL8139 Family PCI Fast Ethernet NIC
Battery rating 6,000 mAh

Prior to it not working at all it would work one day then not the next, this is how it is:
When I switch it on all I get is the backlight in the screen, no power up what so ever, no lights no fan nothing.
When I plug in the power supply i do see the 3 lights light up for 1 second.
My question is this:

Could this just be a faulty (dead) battery, or does the mains supply not work through the battery?
I have tried it with the battery removed and mains plugged in and I still get the rear screen light.

Any Ideas Anyone???
Any Ideas much appreciated

Thanks all.
