HI guis ! I've and old HP PRESARIO CQ60-202EL with Vista O.S. I tried to update it to WIN 7 ultimate but when i try to install, it show to me this message: "Windows cannot be installed on a battery-powered computer. If battery power runs out during installation, some data may be lost. To continue the installation, connect the power supply." Infact, battery level 67% signs that is running without beeing charging. But the power supply led is white and cable gives 17,34 ouput DC Voltage. When i try to enter BIOS with F10 key, F10 key not works ! Only F9 key works (change hdd, dvd or usb boot). So, i tried to update BIOS and download sp45070.exe . When i try wflash.exe the system give a backup of old BIOS (bios.bak - 1063 kb) but is unable to flash the new BIOS (360AF54.WPH - 1063 kB). At this point the system gives to me this message: "PHOENIX WinPlash: BIOS update failed ! Failed to flash BIOS image: WINFLASH can not run in Battery Mode. Plug in AC and try again. BIOS is not flashable. Errore code: -144". Please HELP ME !! Thank you !! Luis

Re: old HP PRESARIO CQ60-202EL with Vista O.S.
No. Without battery it doesn't run !!! It makes only two white led flashes (one of 3 led in front) when you push the power button.Comment

Re: old HP PRESARIO CQ60-202EL with Vista O.S.

Re: old HP PRESARIO CQ60-202EL with Vista O.S.
I think they ran on 18.5 volts. Make sure you have an original or a proven good source, 19 v is ok. This seems like a hardware issue, check the dc in mosfet, first one.Comment

That looks like a two pin universal dc jack ? The middle pin on HP is to detect the charger.Comment

No. It isn't an original ac charger.Comment

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....
