what about get contacts for fix serbuis's brick trouble? PB if it rly, plz =)

Yep. Battery is ok. Chip was soldered proper. I'm sure! )))))) Just I'm remember: in 1st time, then unsolder chip, previously I made a ​dump - i'm pay attention on visual differences of 2 dumps (software shows HEX two versions before flash). Strange, what software bios versions (A11), chip models, .rom file sizes - it was identical. Apart a strange result in fact - mine chip dont work, after reflash on official release... How show mine humble experience, what big difference with same troubles will not to be . But I can be wrong - because dumps was made of two difference notebooks - part and serial numbers, release dates, hardware parts setup and etc. Is all are it logical? I'm not sure. Or I skip some details. Maybe upload to here a .rom file what I'm used in 1st time? And why after official reflash, without errors, warnings, bugs - BIOS work fail and power turned off on external ports? Why, after hardware chip reflash - motherboard send power on external ports, but after again reflash with official tool - no get power again? WTF? Heh, so many questions)))) Will be fine, if I can find binary dump from 7720-3384, created with programming device or without it, damn. (( Maybe, it give chance to help in my trouble resolve . Don't know... Any case, IMHO, problem need solve here - for experience and excluded such failures in future. Regards.

Now in BF3 (835mhz) with thermal paste replace\no external cooling - i get not more ~75-80c, but need to load bios from USB anytime Change MB @ warranty not good idea for me, i think More 5 times i was get\insert rom chip from MB, but i will try after russian's holydays. And, I if can't resolve my "little" problem in next 3 weeks.

attach binary from 7720-6174 readed from chip with programming device. maybe can help someone 7720-6174-A11.zip P.S. Is binary was readed from new NB, but flash it on A11 ver. (from Dell's official site with standart method)

I get a brick, when flash at 970. nb is 7720-3884 What i do: 1. Flash @ A11 from Dell's off site 2. Flash @ AES vMod 835mhz 3. One day later buy Arctic Silver Ceramique and get NB for "turbo mode" xD 4. Try to flash @ 970 mzh - failed on start. When i think what need back on "clean" A11 and do it... 5. But when flash is ok - NB reboot and ... i got brick.. x_X - not read usb with "crysis mode" =( no power on external ports (sata, usb, fans, etc - work only kb backlight and matrix test). For recover I get rom chip from other NB (7720-6174) and create dump with prog device. Then this binary I'm uploaded on my chip and moutherboard can send power and read ROM from USB. But NB not started normally - black screen, fan speed is 0. What now: - reflash with factory flasher A11 - brick. - reflash @ any mod from here - brick. - system can load if rename "boot.rom" to "boot.cap" from 835mod and only from USB (this is ROM i flash before in step 2) - Windows loaded nornally, if after boot ROM from flash enter to BIOS (F2) and exit with save (F10) Any ideas? Work any time load BIOS from flash not fine, I think P.S. I can create binary from my chip, if it can help resolve problem P.P.S. Sorry for bad English ;D
