    Is it the Northbridge?

    I have a Toshiba L500D LA-4971P that was dead except for the power and charge lights. After a bios re-program and a northbridge reflow it will now post. However, it gives a "System Configuration Data Read error" and then wants you to press F1/F2 etc. Changes to BIOS make no difference and the error stays. It won't boot a HDD and gives a "no operating system error". Funny thing is a windows CD sees the drive but the install fails. Several HDD's have been tried. It also won't post if the top Ram slot is occupied.

    Would you say this is a northbridge error, particularly as the reflow managed to get it this far and the dead ram slot is a northbridge symptom too, isn't it?.

          yes , there is problem on south bridge , northbridge as nothing to do with the config data error , this is from IO reading , so give a light reflow on SB , if erro stop , reball or replace

          very common on L500 with grafic module

              so for upper ram slot (version dd3 or ddr2 ) , if ddr3 , replace cpu , if ddr2 , probably bad contact on bad northbridge ,

                      Reflow equipment
                      by tony359
                      Hello all,

                      I am experimenting a bit with reflowing larger components - ideally I'd like to reflow a PS4 APU or a GPU for example.

                      I know it's impossible to reflow such large components with just hot air so I bought a pre-heating plate, T-8280 classic Chinese machine, which seems to be working fine besides it's a little slow, which shouldn't be a big deal.

                      Now, my hot air station is a Aoyue 852A++ and I feel it's a bit weak when used with larger nozzle. I tried reflowing a laptop chipset using one of those large, rectangular, nozzles and I failed miserably,...

                      Concerns before attempting a Reflow of Laptop's GPU
                      by Mr_Nada
                      I saw some posts at one point talking about doing a reflow but I couldn't find them again so I thought that I would post this here.

                      I plan on reflowing the GPU of this old HP DV2500 laptop but I want to go over what I have and the steps I have to take to guarantee it will come out fine.

                      I have a Yihua 8786D 2in1 Rework station, flux (just some paste that I got from an old Radioshack kit), a couple rolls of Kapton tape and a $15 Thermometer +probe (a TM902C from EMR shielding Solutions if its important).
                      • The paper that came with the thermometer states that the probe

                      Google Pixel 5 - Proximity Sensor Issues - Reflow/Replacement procedure tipps wanted
                      by groomit
                      Hi,
                      I just replaced the battery on a Google Pixel 5.
                      After that the proximity sensor isn't functioning properly any more. It is constantly activated. So when playing a voice message on Whatsapp, the Screen instantly turns off.
                      Checking with a sensor app I can verify weird behavior of the sensor. It is triggered when nothing is near and sometimes works correctly when squeezing the phone next to the sensor hole.
                      The rubber seal is on again (as mentioned in various suggestions in other forums).

                      This smells like a cold or broken solder joint. So I'd like to reflow...

                      For BGA reflow experts...
                      by Davi.p
                      I have attempted all sumed very few reflow processes, and i need to make it better, how do you make yours to have sureness that the balls are really fully reflowed? My temptation was always to do "the slight move" touching very gently an angle, but due to some cases, but maybe 100%, where the previously half working device became totally shut off, i finally understood that the damn "move" makes the balls shorted, so what do you suggest?
                      Thanks!.. Muchas gracias.....

                      SEF 551.10 - Error starting the reflow oven.
                      by bpjl
                      Hello,

                      When starting the SEF 551.10 reflow oven, the following problem occurs:





                      It seems to me that this is related to corrupted software. Does anyone have files that can fix this device? Or maybe someone uses such an oven and is able to make a sector copy of the memory card located in the computer controlling this oven?

                      PS.: Of course, appropriate emails for help have been sent to the manufacturer and distributor in my country. No response yet, but I don't expect much. It's a fairly old device and from what I know, it's no longer...
