Following a replacement hard disk being fitted at factory in October, a fault developed - initially a blue error screen which said '' hardward installation error, reinstall or ..'' - then sceen flashed off and notebook performed as normal. Now the sreen is weird - part of the blue screen is visible and then below it is white with lines. I have 3 year extended warranty but having had it collected for repair, they now say not covered and will cost 322 pounds. Is this likely to result from their earlier repair? as I cannot install hardware and therefore cannot have created the error

1. Turn OFF the main power switch and turn it ON again,
and conduct the following setting. [Service Mode] ->
[System 1] -> [Initialization] -> [Data Clear].
I.11.14.8 Initialization-Clear All Data
2 Format hard disk - -
3 Replace the hard disk. - -
4 Replace MFPB

Hello Sir, Hi, the blue screen is commonly caused by a bad memory module. you may need to buy replacement memory modules, ask a computer shop if they have a module for your Mini, and have them replace the it. If the problem still persist, reinstall your Operating System. thats it.

HP 4015 NVRAM & hardrive initialization

Solution
A hard disk initialization will erase and reformat the printer's hard disk. Perform hard disk initialization only if an error code displays on the control panel indicating a disk error. Always try initializing the hard disk before replacing it.

1. Turn the printer on. 
2. As the printer performs its power-on sequence, press and hold the Menu button until all three lights on the control panel are lit. 
3. Press the back arrow . The message INITIALIZE DISK displays on the control panel. 
4. Press OK. The printer initializes the hard disk and continues the power-on sequence.


CAUTION: Initializing NVRAM resets the serial number, the model number, the event log, the page counts, and the EIO card. Use the SERVICE menu to restore the serial number and page counts. You also need to reconfigure any computers that print to this printer to recognize the printer. Initialize NVRAM only when absolutely necessary. In most situations, use a cold reset to return printer to factory defaults but still retain the needed values in the SERVICE menu. 

 NVRAM initialization
Before initializing NVRAM, print a configuration page and a supplies status page to gather the service menu values

1. Turn the printer on and watch the control panel display. 
2. When the display shows the memory count, press and hold the down arrow until all three lights on the control panel are lit
3. Press the up arrow . 
4. Press Menu . The message SKIP DISK LOAD displays on the control panel. 
5. Press the up arrow until NVRAM INIT is highlighted, and then press OK. The printer initializes NVRAM and then continues its power-on sequence.

daca aceasta procedura nu reuseste, atunci va trebui sa inlocuiesti formatter-ul. daca nu exista hard disk

Good luck

check the ram n hard disk

Generally changing the cylinder (blade and developer) and adjust normaly TD sensor and ID sensor, usually it is solved. If it is not thus it proves the following thing: press point and numeral (enter) simultaneously for more than 10 seconds until this is extinguished clarifies the service call. If the problem persists can be the hard disk, change.

What was the error on the blue screen? need the error and the error number. I would check the cable connecting the hard drive to the motherboard and replace it. also try plugging it into a different plug if its sata

Unfortunately this error occurs with a fault hard drive. You will need to replace the hard drive and then reinstall the OS.
