THIS IS THE SECOND POST OF THIS TOPIC. FIRST ONE VANISHED AFTER I EDITED IT. Poofed from the Message Board, Poofed from my own History page, gone.
In Short > noticed that my M7510 was sluggish at boot, and all around compared to my Latitude e6230. Opening the same web pages, same files, same documents was faster on the 2012 12" notebook.
No Boot, No Post, No Error Codes, No Beeps. Just a black screen (display backlight non functional too)
It Will not Detect the Recovery image on (usb)CD, on USB, or from internal SATA disk.
In Feb, there was a BIOS update 1.15.4 that states that it "Updated the handling of 3rd Party Options ROM loading". I had not installed this version, and WAS/AM on Previous 1.14.4 Version String.
I've Searched the heck out of this, and found similar postings here for other dell laptops, but no one ever has a fix. Is this laptop now a very expensive brick?
Replaced Main Board, Issue Resolved.
That said, I find this silly for Three reasons :
1. This board appears to have traces for Dual Bios Chips, but is not Dual Bios Equiped, there is no reason a minor corruption should take out the entire laptop?
2. There is ample space to use socketed user replacible bios chips, it was at one time a staple on machines ( my Dell XT2 semi rugged tablet had a socketed chip 10 years ago) If it ever fried you just undo a spring clip, take the chip out, and you can reflash it easily on a eeprom flash board. OR buy a preflashed chip : these things are like 50cents or less to make (and buy)
3. That 50c chip is soldered to the motherboard, thats then made more expensive due to non-socketed CPU...had this issue occured outside of the service period, it would have cost nearly as much to fix as to just buy a new FASTER computer...
If any engineer stumbles on this Please take note and think about it in the future...to have servicible parts.
