Hello everyone,
I have a T470 type 20HE that does not start: only the green led of the "on/off" button flashes 3 times when you plug the charger and that's all, even the fan does not turn.
Do you think it comes from the BIOS and, if so, is it possible to fix it?
Thank you for your help and cordially...Leave a comment:

T470s / Error 0288 / Black screen / External monitor working [ATTACH]n3241490[/ATTACH]
Hello everyone and thank you for this forum (and in advance sorry if my post does not correspond to its rules)!
My T470s worked well until I changed the screen (with a not compatible?). After that, a series of beeps rang at startup (code 0288 with Lenovo PC Diagnostics) and the screen remains black... I put back the original screen, changed the cable connecting the screen to the motherboard without any improvement. Today, I can still use the T470s but with an external display...

Re: Need bios dump for Lenovo Thinkpad X240
Hello,
I've trouble with a X240 : when I plug it, I see the green power led blinking four times (not three). When I try to boot it, I only see the keyboard leds lighting one time, then the green power led blinking four times once again and nothing else.
I've flash the bios with a "generic" bios found on the net : the laptop start (after a long time because of ME Region I suppose). Then I've tried to change date on the bios but it was impossible because of a supervisor password (and impossible to enter the bios and...Leave a comment:

Re: Lenovo x270 bios+ec
Hello,
To make my bios flushes I use a clip with the programmer CH341A and also with Flashrom.
My X270 comes with the eeprom 25Q128JVSQ and I have problems to have it recognized by these "software": can you tell me which versions to use with both CH341A and Flashrom?
Do you have any download links?
Thank you in advanceLeave a comment:

Re: Lenovo x270 bios+ec
Hello XIBASE,
That’s the exact location. However, the eeprom being very close to the other components, I advise you to file both sides of the clip to guarantee a correct contact and therefore a correct bios dump...Leave a comment:

Re: HP EliteBook 820 G1 Bios
Yes, of course. But I want to know if, for unlocking a bios password, I must make dump(s) of only the eeprom or eeprom AND EC ? And about making the bios dump, must I desoldier it (never do it before) or can I use a clip + ch341A + flashrom or ch341a software or another programmer software (which one in this case) ?

Re: HP EliteBook 820 G1 Bios
Hi everyone,
Thank you first for all the informations and services offered on the site.
I have to unlock a HP 820 G1 (bios locked). It would seem, to make a correct bios dump, that it is necessary, on this model, either desolder the eeprom, or solder wires to it (and dump for only the eeprom, not eeprom + EC). Am I right ? I do not know these technics: would you have a solution that would only require a simple clip? Do you need to use any particular software and, if so, which one ?
Thanks for rour reply and best regards.Leave a comment:

Thinkpad X250 ME region
Hi,
I don't find a thread about this subject for X250, so this is a new one : hope I wasn't wrong...
I've trouble with my X250 (after unlocking supervisor password) : too slow to boot, too slow to enter bios setup... I tried to clean the ME region with Intel Easy clean Me (from ME version 10.0.60.3000 to suitable MEs 10.0.25.1048 according to this tool) as I've did it successfully before with other ThinkPads.
May you help me and tell me what's going wrong this time ?
Thanks by advance !...Leave a comment:
