Re: Acer Travelmate 2700 Bios update failure
Try holding Fn+Esc instead of Fn+B. You can also use a USB flash drive instead of a diskette, it will have to be prepared with DOS system files beforehand though. If you need a guide i can link to it, i'm just too tired right now to search.

Re: Lenovo V570 (V560 series) KBC flash
Just a follow-up: I ended up buying a replacement fan from ebay, which solved all my thermal worries. The original fan was a bit wobbly and didn't rev up to the maximum speed. Still have the laptop, posting from it right now. Working great. :) And it's actually a V560, dunno why i was under the impr...

Re: Lenovo V570 (V560 series) KBC flash
Thanks. Yes there is a serial number on the back. I've googled a bit more and the serial number thing has to do with the main BIOS. There is a BIOS update available. However, i'm unable to flash the BIOS with either Windows or DOS utilities, it reports "unsupported ROM". Ahh well, i might just flash...

Re: Lenovo V570 (V560 series) KBC flash
I got the RAM. Report: SUCCESS!!! :mrgreen: There are a few oddities reported by the BIOS such as the wrong model number and the invalid serial number. I think these are the proofs of a previous bad/incomplete BIOS flash. The guy who sold me the laptop said he sold it as working and it came back 2 d...

Re: Lenovo V570 (V560 series) KBC flash
A bad solder joint can be ruled out. When i first read the chip it was all gibberish compared to the bin that was supposed to be in it, any sequence longer than 3 bytes didn't match between the two. Soldering looks good in general. There were other more sensitive parts than the SOIC-8 flash that wou...

Re: Lenovo V570 (V560 series) KBC flash
So far i have managed to confirm that the flash chip is indeed flaky. After getting accustomed to the Bus Pirate and flashrom, and reading/wiping/rewriting other chips successfully, i pulled the PMC Pm25LD010 from the Lenovo. I had to hack the flashrom sources to support it, as the Pm25LD010 appeare...

Lenovo V570 (V560 series) KBC flash
Bought this notebook a couple days ago to fix and keep for myself, or maybe resell, we'll see. Trouble: No power absolutely. No LEDs no nothing. Not even battery charging LED. I have confirmed the presence of 3.3v and 5v standby, there is 3.3v on the power button as well, but when pressing power not...

Re: Microcode for PIII-S 1.4GHz please?
Can't believe it's been 3 years. I tend to forget about anything that doesn't email notifications to me... My dual Tualatin still runs, i found a Hipro PSU that i fixed, and it's been a perfect match since. *Still* haven't gotten that HD4670 AGP i've wanted to get to max that rig out tho. I've built...

Need to get Acer Aspire One to boot from SDHC
To make a long story short, i have an Aspire One ZG5 that someone ripped the SSD ribbon out of, along with the better part of the connectors. It cannot be fixed even with a hot air rework station as the connectors melt, they probably used infrared or wave soldering on it. I also have a 16GB SDHC car...

Re: Microcode for PIII-S 1.4GHz please?
just for starters: find out what PFC is for and what it has to do with efficiency. sum up the wattage of the different voltage rails (assuming they are independend of each other) and compare it with 420W. What PFC does is keep current and voltage in phase, lowering the stress on the power grid. I d...

Re: Gigabyte GA-8SR533P motherboard dead...
Mixed RAM shouldn't cause any major trouble (except maybe the loss of dual channel), however that doesn't mean that one of the sticks isn't bad. Power up the computer with one stick at a time, and try flashing the BIOS on each. With a bit of luck, it'll get going.

Re: Microcode for PIII-S 1.4GHz please?
Xilence 420W Xilence is a low cost and low quality brand. you should really get something better. if you don't want to spend too much money, i'd recommend the cheaper 80PLUS PSUs from Seasonic or BeQuiet. the brand really doesn't matter. make sure it has a 80PLUS logo (or better). And what about th...

Re: Motherboard ruined??
I just wondered how much damage I have caused. Is it possible to ruin the motherboard in general, or how likely is it that only the BIOS is ruined but the rest of the system is fine ? It isn't possible to damage the motherboard as far as i know. When the right BIOS will be reinstalled the board wil...
