Re: Need bios Acer Aspire 5740

Good afternoon. I need a BIOS on a laptop Acer 5740/5340 model MS2286 JV50-CP MB 09285-1M 48 4GD01 01M.CIP B082 HM55 without video on board. The laptop turns on the duty officer has 3.3 and 5 volts on the throttles after the shim. Nothing appears on the screen no further start. Possible damage to Bios. If anyone can help solve this problem.
