The Dell Inspiron 3480 I own (the all in one, not the laptop) is not wanting to turn on at all. It goes right to a dell logo, but it stays there forever with no other information on the screen. Holding the automatic Bios repair key combo (ctrl+esc) that should let it read a recovery file off a USB drive gets stuck on a black screen and does nothing. No amount of resetting anything so far has worked, and Dell's own support downloads have not really helped. Ive tried another BIN file I found online using my CH341A, and this got me slightly more, that time it displayed a loading bar that never moved... -
Hi,
I have a Dell XPS 9300 that's working perfectly fine with an external display plugged, from windows the internal display isn't detected. At boot I can see the Dell logo then when it should display the boot/bios or whatever the screen goes black (no backlight, no image using a flashlight). I tried unplugging everything on the motherboard except the eDP cable but it didn't helped (so it's not the lid sensor). LCDVDD/backlight power are powered down when this happen, PANEL_BKEN_EC and ENVDD_PCH are also down to 0v. It's weird, it almost feels like the motherboard is shutting down the display...Yesterday, 01:44 PM -
My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?
Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?
My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
I have tried multiple different Dell power adapters. My Dell... -
good morning all,
i purchased a used dell e6540 laptop used 10 months ago from a vendor on ebay. intel i-7 processor, 16 gb ddr3 memory, 256 gb ssd., mobo la-9413p (rev 1.0 dated 2014-08-04). i've inflicted no damage on it since purchase but its past is unknown. starting 2 weeks ago it began to fail to boot (initially 9 of 10 boot attempts failed, now 10 of 10 fail). there was no new hardware or software added (i was using as a kodi video server). the post process doesn't complete and booting no longer displays the dell logo screen - screen remains black with no backlight. some other... -
Hi All,
UPDATE: post was moved to new thread, so editing it ^^'
I'm a totally new to electronic repair, I do play a bit with arduinos, 3d printers, esp32 ... but I'm generally more on the coding/software side for hobby ^^" my electronic skills do not go much further for now ^^'
I decided to start doing some repair, just to avoid throwing things to trash ...
Since I have a broken lcd monitor, I decided to try to get this thing to work for a start ^^"
I have a dell P2412Hb, which seems to be similar setup than the one on this thread https:...09-04-2023, 07:22 AM
