BIOS Flash failure, Doesnt power on

Hi,

I have Dell xps L501x and i flashed my bios. During flashing i got a blue screen which is windows error screen on windows8. Since it froze, i removed my battery and reinserted. From then on the laptop in not powering on. No sound or fan powering up. If i connect charger, the charging light on laptop is not turning on. Completely dead. What might have happened and how do i fix it? Can the bios chip be replaced or entire motherboard?

Hi,

When you say you removed the battery, did you mean the main battery or the coin cell battery on the motherboard?

Here is a link to the service manual for your laptop.

http://downloads.dell.com/manuals/all-pr...

On p.37 it details how to remove the coin cell battery. Removing / replacing this battery will reset BIOS, CMOS and NVRAM and hopefully by doing this you might get it going again, (no guarantees but at this stage if it doesn't work, all that you've lost is some time).

Here is the procedure:

1. Disconnect the system from external power source, remove the main battery.

2. Use the service manual to locate and remove the coin cell battery. Take note of its orientation so that you know which way to re-insert it. If necessary, take a picture of it before you remove it, so you know which side is up.

3. Press the power button for at least 10 seconds to drain all residual power from the system.

4. Re-insert the coin cell battery. See step 2 regarding battery orientation

5. Assemble the unit and verify functionality

Hopefully when the system is powered on, it will warn that the date and time is not set, indicating a successful reset
