Ah yes, How am I supposed to add new bios? I won't get any display so no post so how do I flash the new bios?

I’ve had this issue for over a year and it seems to pop up around BIOS updates. A co-worker and I both had it happen last week, and each of us has had it happen once this week. Our solution has been to pop a stick of RAM out, turn on the machine and it recognizes the memory change, and then turn it off to put the stick of RAM back in. This week is odd because there are no BIOS updates listed in Dell Command, and we’re on 1.21.0. Our RAM sticks are under the back cover. We haven’t done anything with the slots under the keyboard. It will be interesting to see if your movement to under the keyboard is a long term solution, or if it’s just a variation of what we’ve been doing where the laptop recognizes a memory configuration change. The new laptops our company has been rolling out are much slower than the 7550, so an occasional 10 minute “RAM swaparoo” isn’t that bad when looking at the alternative.

Hi all, I came in late here, hope to be of some assistance.. My lapsolved' however none of these repair procedures worked at least for my specific model. Here is the issue: rebooted Laptop, keyboard lights, power light functions. No LCD display (blank). While pressing 'D' and power button simultaneously, the LCD screen checks ok flashing red, blue, green etc... LED status: 5 white and 2 amber flashing with interprets to a memory issue (or similar). Here are the steps that resolved my issue (of course remove all static that may be present): Pull or unplug the charger Remove Laptop Battery REMOVE CMOS BATTERY/LEAD from mother board Plug in the charger/AC and power on the laptop for approx. 15 seconds then remove the charger/AC. IMPORTANT: Remove the memory module from slot 'DIMM 1' and re-install to slot 'DIMM 2'. Plug in CMOS battery/lead Re-install the Laptop Battery Plug in the charger Power up the Laptop This worked and allowed me back into the BIOS Hope this helps..

What is the model? The light diagnostic could be different. Typically it looks like a battery failure. you can run the diagnostics by using the F12 button when you first boot the computer to get to the boot menu. Then choose diagnostic It should provide an error message with more details. Edit: I didn’t see the second picture. Does the battery look flat or swollen? I can’t tell from the angle.
