I tried to delete password on my Lenovo T460s machine.
Everything was OK (STEP 1 to STEP 7) until I restore original BIOS.
Laptop did not power on, just 5 beeps and 5 beeps again.
Tried to flash the patched BIOS back - laptop power on, but not possible to boot / open BIOS.
Flashed back original file and 5 beeps again..
Should anyone please check what I did wrong?
Both bios included.
Thank you very much....

LG 39ln575s - power ON, backlight ON but no screen
LG 39ln575s - power ON, backlight ON but no screen.
I checked TCon board V390HJ1-CE1 and VCL -8V, VCH 30.2V.
Display is HC390DUN. With both strip is backlight only - nothing on the screen.
If I put 1st strip off, I see 50% black 50% white. If I put 2nd strip off, see some lines vertical/horizontal with pink color (probably color of LG logo) and after that, white on thle left corner.
The IC chip CM501 (probably booster for VCL and VCH is hot - after 1 minute is not possible to put finger for more than half second.. So I think it has got about 70C. Is it normal?...Last edited by bajdik; 12-11-2023, 11:20 AM.

Re: NM-C221 - PU2101 (+1.05VALW) burned
Yes, i know, there are two. But burned was PU2101, PU901 had nice 0.95V. Is normal that the corner of the CPU is hotter? The only way, how to this chip should burn CPU is via G2898KD1U, which take +1.05VALW from SY8286RAC. G2898KD1U provide VCCST and VCCSTG voltage for the CPU. But chipset doesn't looks burned..

Re: NM-C221 - PU2101 (+1.05VALW) burned
72 OHM for 1.05VALW
15 kOh for 3VALW
No caps on the PCH is lower than 72 OHM.....

NM-C221 - PU2101 (+1.05VALW) burned
Hello,
I'm not too much experienced man, so I would like to have some confirm about my board..
On the board is burned SY8286RAC, which provide +1.05VALW mainly for the chipset. After changing IC, on the output is 1.05V, laptop is power on, it takes 20V 0.6A stable. Nothing on the screen. The corner on the CPU gerenerate more heat (about 60C), the rest of the CPU is almost cold. Chipset is not burning hot, about 45C. The only way, how to this chip should burn CPU is via G2898KD1U, which is (with chipset itself) the only one which take +1.05VALW from SY8286RAC. G2898KD1U provide...

Sharp LC-40LE830E white blinking after wallplug is off
Hello, on Sharp LC-40LE830E is everything OK. Working great. If I put the 230 V off and on again, it just blinking white standby LED. I can power on only via VOL- and CH+ and POWER button on TV. After that, I can power off and power on again without problem (by buttons or remote control) until the 230 V is connected. If i put the plug off and on again, just white standby LED blinking. TV needs three button starting again.. On the first look, the backlight looks great, no darker or lighter spots. Any idea what is wrong?

HP 15-dc1020nc OMEN picture only on external USB video card
I bought broken HP 15-dc1020nc OMEN laptop.
Power on without screen.
On the board was damaged one mosfet on the GPU power line.
I change this ic but still the same. I think, that the GPU is damaged.
So I bought for 150 USD new Nvdiia chip. Still no picture.
After that, I fixure out the laptop boot into windows (welcome sound). I put external USB graphics card and the laptop works great. In device list, no GPU is listed. I'm not sure if that laptop has integrated intel gpu disabled or not.
Any idea? On the alisaler.com is bios for board and gpu, but is not...Last edited by Vesko356; 04-28-2023, 07:29 AM. Reason: Merging posts. Added HP 15-dc1020nc to the thread title.
