Hi Guys
I have a Lenovo Ideapad 305 laptop here
Long story short - it was brought to me by another alleged repair company. It would not switch on but it would charge the baterry - I fixed this by repairing the flexi ribbon cable from the on/off switch which had a hole in it almost certainly caused by someone putting a case screw through it that was too long
After fixing that, it powers on for a couple seconds then powers off again. Pressing the start button repeats the process. I get no picture, just the fans spin and I hear the HDD spin up. I tried unfreezing the SIO and resetting the BIOS, no difference. Tried with our without HDD, with PSU/Battery and both no difference. Tried with just one DIMM in either slot, no difference.
I can see I have 3.3V and 5V but 1.7V, 1.1V, 1.35V come on for a couple seconds then go off again.
After that I noticed someone has previously desoldered the BIOS and I have no idea what file it has been programmed with
I read the BIOS contents (attached). The Eprom is a GD25B64BSIG and identifies/reads OK
Can anyone give me a known good BIOS file or compare the one I posted with a known good one and tell me if it is OK or not?
Thanks
Richard
