early problem this laptop is short 19v...after replace short capacitor (PC6005), this laptop does running okay...but the problem is battery percentage not increase...charging orange light is normal when insert adapter...
i have try replace 2pcs new battery but also same result...on status it saying "charging" but percentage not increase...this laptop also running okay with only battery (got 27% left)....

Hi everyone,
Someone come to me after his lenovo has made a BIOS update and after never posting.
Board is:
NM-C511 rev 1.0
ideapad_s145-15api (Type 81UT)
S/N: PF1WZ2L8
After full removing AC and battery and cmos battery and pressing power button for 30sec the laptop turns on and every LED and power rail comes fine,
CPU is very mildly warming up but reaction to buttons and no display.
Tryed to reflash bios suggested on this forum but nothing changed.
Tryed to reprogram the EC with vertyanov programmer but the following happens....05-02-2025, 01:06 PM -

Hi
I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.
1. FR950 - blown fusible resistor - 0.2 Ohm 1W
2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
3. R835 - Blown Resistor - 20KOhm SMD resistor
4. D930 - Shorted Schottkey Diode...Yesterday, 10:51 PM -
[B]Dear forum participants,[/B]
once again I have a problem with a possibly damaged bios.
Please upload the file if you could be so kind and check if it is broken or ok?
It suddenly stopped booting after a bios update from version 208 to 212.
[B]Model:[/B] Asus T200TA-CP001H
[B]further number[/B] on the type plate: ECN0CJ128712152C
in the same row as the number above it is still far away: CN:2480
Perhaps someone who is familiar with this can please check the file and possibly go back to 208 to flash with ch341 or ch347.

Hello,
I have a problem with Acer Nitro 5 AN517-52-56A5 (motherboard: GH51M LA-K862P Rev: 1A). I was playing TLoU2, which is a rather demanding game, for a few hours, unless the notebook turned off (my guess is that the battery drained to 0%). Now, when I connect the AC adapter, the LEDs are not coming on and the laptop doesn't charge.
It also shorts the AC adapter - I've checked two of them from different manufacturers. Though the AC adapter gives 19,5V as expected, the voltage drops to 0V when I connect it and disconnect from laptop - it comes back to 19,5V when I reset...05-02-2025, 06:48 AM -
Reply to Lenovo yoga 9-14ITL5 BIOSHi all,
I've Been repairing laptop for a couple of year and this my first attempt at replacing a cpu.
I use a lenovo yoga 9 14itl5, the cpu is tested and working before it being transferred to a different yoga 9 14itl5.
I've clean the Me but nothing else, wondering what Bios modifications need to be made.
Right now The board is definitely on because I got -PLTRST but it doesn't boot to bios

Hi friends
I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board...Today, 02:43 AM -

I found another post on this site the other day which has been very helpful in troubleshooting this issue I am having with my tv. The left half of the screen is dark, and the other half is VERY slow to generate it’s image - and it only generates part of its image at that.
Based on this yt video, I have narrowed it down to an issue (short?) on the left side of the display, somewhere in the system of ribbon cables.
when I remove the bezel and the rear cover, I can get the image to display correctly by manipulating the ribbon cables on the left side which connects the left lower display...Yesterday, 12:19 PM -
I bought a case of them the battery cells are made in China the charge curve looks decent for 1 amp charging rate there is also a BMS protection board which here is the website link to them

Here are more of the same but the difference is that they do not have the BMS protection boards but have the tabbing on them

Hi everyone, I have this gaming laptop that during the usage suddenly shutted down. I disassemble it and take some mesurments. I have a lab supplier and a thermocam. I tryed injected voltage at the DCIN connector and I see this little chip went up to 85 deg (at 19V) this chip should control the battery charge. Next i mesure the resistence at the big coils on top of it and the value is 0,4ohm so dead short.. Those 4 phases are the power supply of the Nvidia GPU?
I tried to inject 1V at that coil and i get 1.35A dwawn but nothing heat up...02-27-2025, 02:56 PM -
