Problem with Dell Studio 1745

Hello

Hopefully some one can help me out ... I recently received a this dell laptop to repair a botched screen replacement all was well after repairing the screen.. booted up the machine and suddenly it wanted a "HDD password" which i thought was weird.. we tried at length and considerable cost to us to find out who had instated this ridiculous "HDD password" with no success, so i figured it must be some form of annoying dell tamper system that was triggered by the previous repairer as I just went straight to repairing the screen * the client was in a hurry * a concept dell obviously cannot fathom.. so my first thought was to reset the bios by removing the battery which obviously does not work.

Any way I started to research the problem and look for solutions the first being Ringing DELL .. which we have done 3 times now and every time We are greeted by a Indian call center tech support, whom are hard to understand and do not seem to have a bloody clue what they are doing, again at considerable cost in phone calls to my client.. THANKS DELL!  and all the passwords provided DID NOT WORK... all the parts are original and nothing has been changed since it was manufactured.. the cheek of dell was to suggest that we buy a new moving parts hard drive for £59 + VAT! when the supplied passwords did not work ... which I also now know would not have worked replacing the hdd will not help.. THANKS AGAIN DELL!  and thank god I told the client to decline and we would look into getting it a Solid State Drive. So I test another drive from a different laptop.. guess what totally clean unlocked drive "ENTER HDD PASSWORD" .. what on gods green earth are you doing dell!

So at this point both me and the client are very annoyed ... and client is obviously very upset she is going to loose her laptop and DATA.. not only are you costing them money in phones calls for wild goose chases to find the password but you are costing them money in phones call to yourselves and then costing them even more money in my hourly rate and robbing them of the precious moments and personal belonging in the form of holiday Pictures, Itunes etc .. Need I go on 

So I try and flash the bios it was on A01 so I try to flash it to A03 hoping it might be a solution and can not again you make this absolute hassle and pain in the rear end because you presume every one has a working 64 bit windows installation *how bloody stupidly presumptuous* then your peace of junk phlash64 tool will not flash with out the battery and AC charger error code -144 presented GRRR.. so lucky for us mere consumers and indy techs you have provided a msdos version  PHLASH16 and can flash from ms-dos but then still this does not help with the HDD password REMEMBER its a HDD password I know you people at dell have some problems remembering how to count to 3 let alone what type of password the bios is asking for ...

So I Further my research and eventually finding a open source code generator and try it on the SERVICE TAG which is not a recognized service tag so I try to generate the code with appending -595B  ... guess what the code generator starts giving me some of the same codes that dell gave me already OK fantastically JUNK! so I get hold of the official "Dell Bios Reset.iso"  which seems to be frankly out of date but this one can work off the HDD SN or Service TAG or Express service code supposedly, but No it will not work or generate a code for my "service tag" even by appending the -595B or 2A7B  prefix.. but does generate against the hdd SN or Express service Code how ever again none of those codes work and guess what they are they are the same codes dell tried to provide previously....

I found out dells state secret flashing method that needs the bios HDR file its the only thing I have not tried yet because I need to Now use LINUX or a HEX editor to extract the HDR file as they fail to provide the Studio 1745 bios installer command line switches to create the HDR under windows/dos once again .. this is simply just not convenient even for a engineer 

SORT IT OUT DELL you can just go round bricking peoples laptops and then trying to rip them off by selling them a  hard drive that will not of solved the problem ... simply because my clients screen needed replacing and because its out of warranty and your monkeys in  India do not have a clue what peace of information actually generated the code in the first place 

I think it might be too new for Paper clip thing .. I can not find the KS2402C chip to try .. if i could i certainly would then have to dell with dell ..

I expect a viable solution to this or I will advise the client take dell to small claims court for the cost of the laptop, phone calls to dell, my time incurred and pain and sufferance from loosing her computer and data and never recommend dell laptops to any clients of mine ever.

Thank you very much in advance any advise or help will be very much appreciated.
