Hi,
I have a Dv7 3101sa with a blank screen upon start up. All the lights come on, with the cap lock/ number lock flashing. The number of flash's is 2 than a 3-4 second pause. it does this for about 2-3 mins than the laptop shuts itself down, than restarts by itself this time with a continuous flashing of the caps/numb lock. It will do this for a further 3-5mins before finally shutting down.
I’ve tried doing a hard reset a few times but no joy. I've reseated the HDD and memory modules and also the comms battery. Still no joy.
I’ve read up on the flashing error code and the 2 flashes when i first power on the unit seem to be a bios corruption. I have no idea what the continuing flashing means when the laptop shuts itself down and restarts. Maybe a faulty cpu?
How do i fix the bios on a blank screen? Tried the win+b buttons on start up and i get nothing, just the same blank screen.
When the laptop was working i did notice that the laptop would get quite hot under normal usage and the fan seemed to always be working hard. The battery was dead so i could only power the laptop with the ac charger plugged in. I've recently broght a new battery after the laptop died.
Had the laptop for about 3-4 years and would really like to fix it, rather than getting a new unit. If anyone can help with this problem it'll be most appreciated.
Thanks.
