Laptop won't boot (Logo screen),can't boot from USB/DVD or access BIOS

Hello, found this

Ok mate sorry late reply usually there is a cover on the underside of the machine unless it is a late version one and all you need to do is to unscrew the fixing screw usually a small cross head one and lift off the cover.
The same goes for the RAM if you ever need to upgrade it.

The late version models I spoke of are different insomuch that one has to remove the whole bottom plate from the machine and in some that is easy some are real pigs to get off. A pic of the bottom would be good to see.

PS Make sure you have the adaptor and battery removed before you attempt any of that.

Ok have found this and I think it may be very similar to the machine you have


If you go ahead just a tip place the machine on a large preferably white bath towel (taped the table top) - this stops the small screws from bouncing off any hard surface and onto the floor where you will invariably have great difficulty in finding them.

Ok mate see my pic I snipped one from that video and the battery is the long (about 250mm) object at the rear of the unit. There is a small latch you need to depress and slide the battery out - usually it is two locking latches but I can only see the video maker actuating one.

Now it is worth a try removing the drive mate as we have to cover all options.

PS If I am a long time getting back it is because my net connection is pretty pathetic where I am right now

Actually I guessed that is what you meant and if that is the pic of your machine I cannot see the BIOS battery only the hard drive (in aluminium caddy) and possibly the spare slot for more RAM.

So if you have seen the round battery in your travels yes it is the BIOS one and removing it and leaving it out for a few minutes will clear the BIOS settings to default when you replace it.

The drive I think what the others meant was try accessing the BIOS with it out - worth a try in any case will ot do any harm.

I can only say it again: Thank you so much for your patience and your explanations.

I have taken a screenshot from a video I've seen (min 7:35): https://www.youtube.com/watch?v=IbwY96pPDyE
I am not sure wheter I got, what the BIOS battery is. Could you please verify it?
According to the video it's super complecated to get to the BIOS battery (assuming I am right) in this model.
Anyway, it is being late here in Germany, I'll go for the BIOS battery during the next days.
Of course, I will try the boot without hard drive thing first - once again: thanks for your clarification here.

I'll keep you updated - and will probably come up with tons of new questions.

No problems mate that is what we are here for. The battery that is in your pic looks to be the BIOS battery it should be silver coloured (usually) the size of a medium coin and have something like CR2032 on it. See my pic/s the RTC means the CMOS/BIOS battery
